Callide Dam Gates ProjectCallide Dam, Biloela, Queensland
This maintenance project has been set up to investigate, repair and restore Callide Dam’s gates to address intermittent occurrences of vibration during their operation. This project will ensure ongoing dam safety and long-term water security.
Safety and emergency management
In June 2021, Sunwater issued a Section 399B notice to the Dam Safety Regulator. This notice means that Callide Dam is now operating at a reduced full supply level (FSL) to enable work to be completed as part of the Callide Dam Gates Project.
The top of the concrete spillway crest became the maximum height of the dam (100 per cent) and the temporary FSL, and the project’s operational level was set at 69 per cent.
Prior to issuing the notice, the top of the concrete spillway crest represented 41 per cent of the dam’s capacity, however, throughout the project Sunwater will refer to the top of the concrete spillway as the dam’s FSL of 100 per cent.
In the instance of extreme weather events, the water level reaching 100 per cent signals a forthcoming spill.
As investigations and some of the work to resolve the gate vibrations are now complete, the dam’s operating level has been increased from 69 (38,160ML) to 94.1 per cent (52,098 ML) of the temporary full supply level.
The increased operational level will allow for approximately 14,000 more megalitres to be stored in Callide Dam, should it receive further inflows this wet season.
In instance of inflows and the storage reaching higher than 94.1 per cent, slow releases will be required to return the storage to the project operational level as soon as possible. If a weather event occurs where it is expected that water will reach the fixed spillway crest, the gates will be manually and safely raised above the water level.
This change will not impact the Callide Dam Emergency Action Plan and based on ‘fill and spill’ scenario mapping of historical Callide Dam data, between the months of December 2021 and May 2022, the probability of Callide Dam spilling remains low. We expect the temporary FSL will have little impact.

Development and evaluation of a reservoir model for the Chain of Lakes in Illinois
Forecasts of flows entering and leaving the Chain of Lakes reservoir on the Fox River in northeastern Illinois are critical information to water-resource managers who determine the optimal operation of the dam at McHenry, Illinois, to help minimize damages to property and loss of life because of flooding on the Fox River. In 2014, the U.S. Geological Survey; the Illinois Department of Natural Resources, Office of Water Resources; and National Weather Service, North Central River Forecast Center began a cooperative study to develop a system to enable engineers and planners to simulate and communicate flows and to prepare proactively for precipitation events in near real time in the upper Fox River watershed. The purpose of this report is to document the development and evaluation of the Chain of Lakes reservoir model developed in this study.
The reservoir model for the Chain of Lakes was developed using the Hydrologic Engineering Center–Reservoir System Simulation program. Because of the complex relation between the dam headwater and reservoir pool elevations, the reservoir model uses a linear regression model that relates dam headwater elevation to reservoir pool elevation. The linear regression model was developed using 17 U.S. Geological Survey streamflow measurements, along with the gage height in the reservoir pool and the gage height at the dam headwater. The Nash-Sutcliffe model efficiency coefficients for all three linear regression model variables ranged from 0.90 to 0.98.
The reservoir model performance was evaluated by graphically comparing simulated and observed reservoir pool elevation time series during nine periods of high pool elevation. In addition, the peak elevations during these time periods were graphically compared to the closest-in-time observed pool elevation peak. The mean difference in the simulated and observed peak elevations was -0.03 feet, with a standard deviation of 0.19 feet. The Nash-Sutcliffe coefficient for peak prediction was calculated as 0.94. Evaluation of the model based on accuracy of peak prediction and the ability to simulate an elevation time series showed the performance of the model was satisfactory.

Threedimensional inverse design and fluid flow numerical simulation for centrifugal impeller
YANG Wei, WANG Fu-Jun, WANG Hong
(1.College of Water Conservancy and Civil Engineering, China Agricultural University, Beijing 100083, China; 2. Institute of Nuclear and New Energy Technology, Tsinghua University, Beijing 100084, China)
In order to solve the problems of traditional design methods, which are mainly rely on experience of a designer and the design cycle is often too long, a threedimensional (3D) inverse design method was used to design the impeller according to given flow field conditions. The method has a better control ability of design outcomes during the design procedure. Based on the inviscid and potential flow assumption, a 3D velocity field in centrifugal impeller is decomposed into an averaged circumferential flow and a periodic one; subsequently they are solved numerically in the twodimensional meridional plane and the bladetoblade surface to approximately obtain the 3D fluid flow field. 3D geometry of a blade is established according to the slip boundary condition on the surface of the blade, the flow field in the designed impeller is obtainable simultaneously as well. A centrifugal impeller was designed by a 3D inverse design code developed by the authors, also a 3D steady, turbulent fluid flow in the impeller was simulated by using a CFD code to examine the flow field and evaluate the impeller performance. The viscous fluid flow simulated and inviscid one obtained in the design are in qualitative agreement, confirming the validity of the 3D inverse design method. The results indicate that combination of the inverse design method and the turbulent flow simulation technique can shorten design cycle and improve design quality effectively. This design strategy may be applicable to impeller design of the rest type of fluid machine.

Seepage Analysis and Control for Dams. Change 1
CORPS OF ENGINEERS WASHINGTON DC
Pagination or Media Count:
This manual presents the fundamental design principles and guidance concerning seepage considerations for design of new dams and the evaluation of existing projects. All earth and rock-fill dams are subject to seepage through the embankment, foundation, and abutments. Concrete gravity and arch dams are subject to seepage through the foundation and abutments. Seepage control is necessary to prevent excessive uplift pressures, sloughing of the downstream slope, piping through the embankment and foundation, and erosion of material by loss into open joints in the foundation and abutments. The purpose of the project, i.e., long-term storage, flood control, etc., may impose limitations on the allowable quantity of seepage.

Dredge pumps are usually operated at part-load conditions, in which the low-solidity centrifugal impeller could experience large internal energy dissipation, related to flow separation and vortices. In this study, SST k- and SAS-SST turbulence models were used, in steady and unsteady simulations, for a low-head centrifugal pump with a three-bladed impeller. The main focus of the present work was to investigate the internal energy dissipation in rotating an impeller at part-load operating conditions, related to flow separation and stall. The unsteady nature of these operating conditions was investigated. Performance experiments and transient wall pressure measurements were conducted for validation. A methodology for internal energy dissipation analysis has been proposed; and the unsteady pressure fluctuations were analyzed in the rotating impeller. The internal power losses in the volute and the impeller were mostly found in the centrifugal pump. The rotating stall phenomenon occurred with flow separation and detachment at the part-load operating condition, leading to a dissipation of the internal energy in the impeller. The rotating impeller experienced pressure fluctuations with low frequencies, at part-load operating conditions, while in the design operating condition only experienced rotating frequency.

Qatar public works authority Ashghal has commenced excavation of a 10km outfall tunnel, as part of Mesaimeer Pumping Station and Outfall project that started in May 2018, to provide a solution for the discharge of surface and storm water in the country.
Ashghal inaugurated the operation of the tunnel-boring machine (TBM) that will be used for the excavation.
The tunnel will be excavated at a depth of 15m below the seabed and about 3.7m in diameter.
The excavation will be carried out using a TBM that uses Earth Pressure Balance (EPB) technique and is designed to operate in a range of ground conditions in Qatar, and with the variable geology along the tunnel.
The second phase of the project includes a pumping station with 10 pumps and auxiliary facilities. The pumping station will be located at the end of Mesaimeer Tunnel south of Hamad International Airport and will operate at a capacity of 19.7m³ per second.
It is intended to pump water from Mesaimeer Tunnel, which was completed in 2016, to the new outfall tunnel.
The project is intended to decrease the surface water level and reduce pumping costs in construction projects around the country and will also preserve the foundations of buildings, and reduce land subsidence due to rain.
The project has been designed to preserve the marine environment, as the water complies with the environmental assessment standards, and will be discharged 10km off-shore.
Excavation works of the outfall tunnel and the construction of Mesaimeer Pumping Station are scheduled to be completed by the fourth quarter of 2021, at a total cost of about QAR920m ($253m).
A joint venture between Hamad Bin Khalid Contracting and PORR Qatar Construction is implementing the project. Mott Macdonald has been appointed to provide project management services, which will oversee the design, implementation and operation of the project.
The contractor will maintain and operate the project for a period of at least three years.
The tunnel extends below the F-Ring Road for 10km with a depth of about 30m below the ground surface.
The main tunnel is linked to the existing and planned drainage networks in the areas and will collect and discharge surface water from 170km² of catchment area, as it is connected to rain water drainage networks in 43 vehicle tunnels.

Hyderabad: People expected that the water levels of Osman Sagar and Himayath Sagar would rise considerably but enough water was not accumulated in these water bodies. Perhaps it is due to the illegal constructions in the catchment areas of both these lakes. After the protest by NGOs, Govt. issued orders but they were not implemented.
It may be mentioned that the total capacity of Osman Sagar is 1790 ft. It has the capacity to store 3900 TMC of water whereas the water level of Himayath Sagar is 1736.5 ft. It can store 2967 TMC of water. However, during the heavy rains last week, only 50 cm. water level was raised. Till yesterday, water level of Osman Sagar was 1777.9 ft. which went up to 1777.950 ft. In the same manner, the water level of Himayath Sagar is recorded at 1748.75 ft. which rose to 1748.80 ft.


By the end of 2012, the installed capacity of electric power in China reached 1,144,910 MW.[more]
d) In the rockfill dam work with inclined core walls, POWERCHINA has come up with criteria for hydraulic fracturing in core walls, which has been applied widely.
The Nuozhadu rockfill dam, with a maximum dam height of 261.5 m, a total reservoir area of 237*108 m3, an installed capacity of 5,850 MW, and an annual power generation of 23.9T W•h,is scheduled for completion in 2016.
4) Energy dissipation in reservoir discharge
The discharge power of the Er'tan hydroelectric project designed by POWERCHINA is 39 GW, ranking the 1st in high arch dams around the world. The Xiluodu hydroelectric project, with a flow of 52,300 m3/s for a 10,000-year flood and total discharge power of 100 GW, has the highest discharge power for any arch dam projects in the world.

7) POWERCHINA is experienced in application of extra-large-capacity generating units.
In the 1990s, China built the Er'tan Hydropower Station, which has a unit capacity of 550 MW. In this century, it completed the 32 X 700 MW Three Gorges hydropower station . The Longtan hydropower station was built with nine units of 700 MW each; the Laxiwa and Xiaowan hydropower stations, both under construction, will have six units each, 700 MW each unit; the Xiluodu Power Station has 18 units, 800 MW each unit; the Xiangjiaba Hydropower Station has eight generating units, 800 MW each unit; the Baihetan and Wudongde hydropower stations will be installed with approximately 30 generating units, each with a capacity of 750-800 MW.
These large units were partly designed, manufactured and installed by POWERCHINA, with the exception of those for the Three Gorges project. POWERCHINA leads the world in research on adaptability of super-large-capacity generating units to the project sites, the requirements for arrangement of powerhouse and project complex, and the selection of mechanical and electrical equipment.

GUWAHATI: Almost after eight years works has started in the NHPC Limited's 2000 MW Lower Subansiri hydro power project along Assam-Arunachal Pradesh.
Lower Subansari project had snowballed into political issue during the 2014 Lok Sabha election.
Work at the project site came to halt since 2011 following protest of anti-dam groups.
A senior official associated with the project who do not want to be named told ET, “Ceremonial work started on Tuesday. First we have to take up massive repairing works at the site. Contractors for the project are yet to arrive. We are expecting to complete the project in next four years.”
Around 60 percent of the work of the power project is almost completed. Construction at the project site started in 2005 and the project was slated to start operating 2014.
The initial cost of the project was Rs 6,285.33 crore however later it increased three times. NHPC has invested close to Rs 8000 Crore. The revised cost estimate of the project is Rs 17,000 Crore.
The project as envisaged by Brahmaputra flood control commission as back as 1955 was a multi-purpose project primarily for flood control and irrigation. Later on the Brahmaputra board handed over the project to NHPC in May 2000.


LAHORE: Tarbela Dam on the Indus River reaches its lowest point today as the water level was measured at dead level i.e. 1,398 feet, as a result of unusually low inflows during the summer months, exacerbating the water crisis in the lowlands.
A calamity of this nature would further constrict flows downstream, reduce drinking water supplies, and negatively impacting standing crops.
This year, on March 20, 2022, the water storage capacity of the Tarbela Dam dropped to its minimal level, leading to a drastic fall in irrigation supplies and hydroelectric power output amidst extended periods of load-shedding.
The current lower trend in river flows portends disaster for the agriculture sector, which is already struggling under an unprecedented heatwave, which causes abiotic stress in plants. According to the WAPDA report, the river inflows and outflows at Tarbela, Mangla, and Chashma on May 22, 2022, as well as the reservoir levels and barrages, were as follows: Indus inflow at Tarbela, 82,800 cusecs and outflow, 95,000 cusecs; Kabul inflow at Nowshera, 28,700 cusecs and outflow, 28,700 cusecs; Jhelum inflow at Mangla, 36,100 cusecs and outflow, 33,800 cusecs;Chenab inflow at Marala, 31,400 cusecs and outflow, 21,400 cusecs.
In addition, the inflow and outflow conditions at barrages were as follows: Jinnah inflow, 107,100 cusecs and outflow, 99,600 cusecs; Chashma inflow, 120,600 cusecs and outflow, 115,000 cusecs; Taunsa inflow, 113,200 cusecs and outflow, 89,100 cusecs; Panjnad inflow 11,600 cusecs and outflow 0 cusecs, Guddu inflow, 66,900 cusecs and outflow, 62,300 cusecs, Sukkur inflow, 44,400 cusecs and outflow, 16,500 cusecs, Kotri inflow, 7,200 cusecs and outflow, 100 cusecs.
Tarbela minimum working level, 1,398 feet; current level, 1400 feet; current consumable water storage at Tarbela 221,000, water maximum conservation level, 1,550 feet; live storage on Sunday, 0.059 million acre feet (MAF). Mangla minimum working level is 1,050 feet, the current level is 1,085 feet, and the maximum conservation level is 1,242 feet, current consumable water storage at Mangla 118,000.


ATM conducted a comprehensive design and permitting effort in support of the Bimini Inlet Dredging Project. ATM performed an Environmental Impact Assessment for the project to obtain project approval.
Chronic sedimentation of the channel into North Bimini had reduced the navigability of the channel and had a profound impact on the economy of the region. In addition to the design of an improved navigation channel, the inlet-dredging project included determination of the optimum plan for placement of the dredge disposal: sand dredged from the project will be used for the renourishment of North Bimini beach.
A series of four rock groins would also be designed and constructed to retain a minimal beach planform.
ATM is providing construction oversight through constant communication and scheduled site visits with the contractor to monitor progress and address field condition changes. The project is expected to be completed in April 2006.

Open-Channel Flow / Edition 1 by M. Hanif Chaudhry


An interactive system for modelling of multiphase inflow performance of long, highly deviated and horizontal wells is presented. It's prime areas of use are design of well trajectories and completions, and evaluation of wells inflow performance including calculation of well indices for full reservoir simulation. Further, the system provides a basis for improved integration of the reservoir engineering and the well completion design. The reservoir pressure and multiphase flow distribution is modelled accurately using a finite element method combined with automatic local grid refinement around wells. A comprehensive multiphase wellbore flow model is available for accurate flow modelling in the wellbore. A well inflow model including a generalized formula for calculation of well indicies of wells in arbitrary directions is proposed. Examples are given showing improved inflow performance calculations using the new well indices.

The water level inputs to the SIMPDEL model were derived from the South Florida Water Management Model (SFWMM), developed by the South Florida Water Management District and Everglades National Park. SFWMM is a large-scale mathematical model of the present network of canals, structures, levees, and pumps that make up the highly managed water system controlling water levels and flows throughout the area [FNJ+94]. The current water level inputs are averaged weekly data from the period 1966 through 1989, although daily data are also available. The spatial level of resolution is at the 2mi scale, which is too coarse to model individual animal movements. Therefore, spatial data interpolation is used to redistribute water levels at the 2mi scale to the 100m scale, based on expected depths for the vegetation types represented in each 2mi cell. This results in a 100m resolution map that approximates the water level in each vegetation cell. Water levels at the 500m scale are then computed by averaging the levels in the 25 constituent 100m cells.


Sand boil contained
Members of the U.S. Army Corps of Engineers work to contain a sand boil at the base of the Mississippi River Levee at New Madrid Thursday afternoon. Jamie Evans (standing lower right) directs the placement of sandbags by Bryan Putt as Nick Schrup (standing upper left) and Randy Clark (standing upper right) wait with additional bags. The sand boil is due to pressure of the rising water against the river levee. By raising the water level around the sand boil, Evans said, they will slow the seepage of sand from the hole and preventing a weakening of the levee. The river is expected to crest at 43.5 feet on March 3.


For more on the Flint River, see the New Georgia Encyclopedia.
The Flint River originates in southern Fulton County as groundwater, which runs underneath Atlanta’s Hartsfield-Jackson Airport. As more creeks join the flow, the river widens and flows southward through the Piedmont and western part of the Coastal Plain area of Georgia. It empties, along with the Chattahoochee River, into Lake Seminole just across the Georgia/Florida border. From Lake Seminole, the Apalachicola River flows southward into the Gulf of Mexico.

Flow Control Valve: Definition, Types, Components & Working Principle
What is Flow Control Valve?
Flow Control Valve: Definition, Types, Components & Working Principle :- Flow regulating valves are also known as speed control valve. The primary function of the flow control valve is flow control in a pneumatic system and regulates the pressure of flow of fluid. Flow control valves in hydraulics are used for controlling the volume of fluid which is supplied to different parts of the hydraulic system.
The speed of the actuators which is being used in the hydraulic circuits can be controlled by regulating the fluid flow, to carry out this regulation operation we need devices and the device which is providing that regulation operation is flow regulation valves.
Compensation of Temperature Change in Flow Regulating Valves
In addition to the pressure compensation the hydraulic systems are having the temperature problem as well, lot of moving components are there and the friction of the moving components is generating the heat energy. As the temperature is increasing that is affecting the viscosity of the hydraulic fluid, the viscosity will be reduced. As the fluid viscosity is reduced, flow rate is changed. By reducing the area of valve opening, the fluid flow can be reduced and by increasing the area of the valve opening fluid flow can be increased.
Flow Regulating Valve Example in Daily Life ( Tap)
Household tap is a very common example of flow regulating valve. Flow regulating valve in household tap contain flow adjustment screw having a ball. By rotating the flow adjustment screw, orifice area can be varied. If the area is reduced then the flow would be restricted or minimized. As the area of orifice is increased by rotating the flow adjustment screw more amount of fluid will pass through the passage.
Components of Flow Control Valve
1. Valve Body
It is also known as shell. It is used as primary pressure boundary of valve. Everything is being hold together by the framework called valve body. The inlet and the outlet piping is received into it with the help of bolted, welded joints. It is cast into various shapes in which the cylindrical and the spherical is the economical one.
2. Valve Bonnet
It is the cover provided for the opening in the body of valve. The body is split in two parts which is bolted together. Some valve bonnets used as a valve covers only while some of them are used for support valve internal accessories like actuator, stem and disk.
3. Valve Trim
It is referred to the elements which is present in internal of a valve. It consists of stem, sleeves, seat and disk. The performance of the valve can be ascertain by seat and disk interface.
4. Disk and Seat
Disk is a element which allow and restrict the fluid flow. When disk is at closed state then total system pressure is exerted on the disk and the outlet side is depressurized. Seating surface for a disk is provided by the seat.
It is that element which is responsible for the connection of actuator and the disk and keeps the disk in its position. The connection of stem with the disk is done with the help of threaded or welded joints. There are two types of stem non- rising stem and rising stem. In rising stem when valve is open then the stem will rise above actuator. And in case of non rising stem there is not any upward movement of stem.
6. Valve Actuator
It is the element by which stem and disk assembly is being operated. It can be operated manually or by electric motor.
7. Valve Packing
This element is used for packing in valves which in result prevents the leakage between stem and bonnet.


KATHMANDU, Nov 30: Nepal Electricity Authority (NEA) Executive Director Kulman Ghising has instructed the contractor company to complete the construction of the 111 MW Rasuwagadhi, 42.5 MW Sanjen and 14.8 MW Upper Sanjen hydropower projects which are being constructed under the leadership of the Chilime Hydropower Company as soon as possible.
After the projects which have investment from the public under the people’s hydropower program were delayed, NEA has instructed the contractor to complete the work of the projects under its own and subsidiary companies as soon as possible.
Executive Director Ghising has instructed to complete the remaining work as soon as possible after discussing with the project management, construction contractors and consultants while monitoring the construction site. When Ghising was the managing director of Chilime, he had managed all the three projects and moved them forward together. “The construction of the main infrastructure has been completed. The rest of the work should be carried out in parallel and completed within 7/8 months.” Ghising said. “The construction of the project, which also has public investment, should be completed as soon as possible and the investors should be rewarded.”
The construction of the projects has been affected due to various natural disasters such as flood, earthquake and COVID-19 pandemic as well as obstruction at the Indian border, difficulties in transportation of construction materials and equipment, difficult geographical conditions, complexity in contract implementation and poor performance of the contractor.
Similarly, while the overall construction progress of the Upper Sanjen is 91 percent, Sanjen’s overall construction progress is 83 percent. Also, the construction of the main structure of Rasuwagadhi Hydropower Project has reached the final stage. The contractor of civil structure and hydro-mechanical equipment has committed to completing its work within the next four months. The construction of the project has been affected due to electro-mechanical contractors.
The electricity of all the three projects will be connected to the 220 KV Chilime Hub substation under construction. The construction of Chilime and Trishuli 3B hub substations and Chilime-Trishuli 3B hub substation is targeted to be completed by next mid-June and July. The electricity produced by these projects will be connected to the national system through this transmission line.

Preliminary design of drainage structures for photovoltaic plants, wind farms and civil infrastructure.
In addition to the hydrological and hydraulic modelling (water velocity and levels) described in the previous phase of the hydrological survey, we then proceed to define the drainage flow lines according to the slopes of the terrain, the lay-out of structures throughout the plant and the potential discharge points of each project. Once the drainage lay-out has been defined, we then calculate the internal and perimeter channel sections using simple calculation methods such as HCanales software, among others, which use the Manning equation.
In the latter phase of the project, and once the drainage system has been defined and agreed with the client in accordance with the project requirements, the hydraulic engineering team of GMS Internacional then proceeds to build the design of said drainage system using AutoCAD with the purpose of providing the client with the necessary construction plans to execute the work on the ground (see our section on hydraulic engineering).

Preliminary, detailed design and construction engineering
The existing Downie Sanitary Lift Station was aging and under capacity - increasing demand meant it had to be replaced.
The new station was sized to handle the existing peak flow of 137 L/s with 3 x 60 HP pumps and allowed for a future peak flow of 206 L/s by providing capacity for replacement of the pumps with 3 x 85 HP pumps. The pumps were carefully chosen so as to have the same discharge connection for ease of replacement.
A new station building was also constructed as part of the project. Inside the building, stainless steel piping was used for its corrosion resistance. The motor control centre (MCC) room utilised adjustable speed drives to control the wet-well level through fluctuating flows and to prolong the life of the pumps.
A diesel powered generator was also incorporated into the building for emergency back-up power. This Genset was sized to accommodate the current station systems and the future 85 HP pumps. The system uses a PLC based controller to provide monitoring and control of the system.

The HAWB herein defined have been designed to be part of the Hydraulic Power System (HPS). The HAWB stores sufficient energy to guard against short duration supply interrupts and to reduce the pressure ripple generated by the Engine Driven Pump (EDP).
The HAWB has been designed to be used in a type II, 4000 psi hydraulic system.


The pumping station is a floating pontoon with an anchoring system 18 metres long and 14 metres wide. It will be equipped with three 1,000 m3/h D-type rotor pumps and a new 2,500-metre long D600 penstock. It will be powered using NWPC’s integrated switchgear.
A floating pumping station is cheaper to construct than a stationary one and helps to deal with water level fluctuations providing best water intake conditions.
The commissioning is scheduled for the second quarter of 2023.


Our variable level control switch can be used to monitor liquid level conditions in pump tanks and lift stations. This particular float comes with a 20′ cord. Intended for use with a control panel, the variable level control switch can be used to activate pumps or alarms. Some of the more common places the switch is used include pump chambers, dose tanks, sump pump basins, holding tanks, lift stations, and other non-potable water applications.
This variable level control switch is normally open when hanging vertically above the liquid level. The switch is engaged when the rising water level lifts it a few degrees above horizontal. This causes an internal circuit to close which activates a pump or alarm connected through the control panel.
The float is constructed of durable PVC and polypropylene. The materials of construction enable the switch to withstand the harsh wastewater environment.
This particular float can be paired with a wide range of our nonautomatic pump models and our Pivot Series Control Panels.

Themes: (T) Flood risk management and adaptation, (ST) Flooding along in rivers and coasts, Poster pitches
Parallel session: Poster pitches: 15L. Flood Risk - Flooding
Hydrodynamic models are used in flood modelling to estimate flood peaks, duration, flow time series and flooding extent. One of the most important components of a hydrodynamic model is the topography of the study area which is represented by the grid discretization. Sobek tool of Deltares was used to build the hydrodynamic model of the Niger Delta using SRTM DEM grids to replicate floods that had occurred in 1998, 2005, 2006 and 2007. The model was calibrated using frictional values for the channel and floodplain, and verified based on the 2007 Niger River flood map; and results showed flood location and partially the flood extent. With the availability of surveyed river bathymetry the topography was improved in discretization and the model was recalibrated. The model outputs (like flood peaks, flood extent and modelling time) based on different grid cell sizes show the model sensitivity to changes in the source of topography. A comparison of the two (old and new models) results is undertaken and a sensitivity analysis of the Sobek model to frictional and topographical change is presented. The model calibration conditions are also discussed.

The transition towards a new risk approach for the Dutch national safety assessment of primary flood defences has been taken as an opportunity to improve the dealings with uncertainties. The probabilistic models for the new safety assessment (WBI2017) not only deal with the natural variability, but also with so-called epistemological uncertainties. One class of epistemological uncertainties is the model uncertainty in the hydrodynamic models used. According to WBI2017 the model uncertainty related to water levels is included by considering the water level as an additional stochastic variable. The quantification of the water level uncertainty depends on the dominant hydraulic processes in each water system and is chosen to be independent of the return period. However, water level frequency lines derived including model uncertainty sometimes conflict with the physics. The main objective of this thesis is to analyse how model uncertainties affect the water level frequency lines in different fresh water systems in the Netherlands and to provide insights into different methods to deal with model uncertainties for the Dutch national safety assessments. A comparative analysis is carried out to assess the performance of Hydra-NL w.r.t. observations and to analyse if physical processes that play an important role in each fresh water system are represented correctly after the inclusion of model uncertainty with the WBI2017 method. This study shows that the estimated exceedance probability of actual water levels in the tidal river area and lake area are often overestimated by the Hydra-model even without model uncertainty. When model uncertainties are included the overestimations become even larger. Furthermore, the inclusion of model uncertainty sometimes gives an incorrect representation of the underlying physical processes. The effect of the model uncertainty gets larger when the water level frequency line becomes flatter. This is e.g. the case at locations where the water levels are influenced by the closure of the Europoortkering and upstream of the flood channel near Veessen-Wapenveld. It can be argued that water level uncertainties are likely to decrease in these situations, because a reservoir is more predictable than a flowing river and the operation of the flood channel results in an enlarged conveyance that is less sensitive than an average river profile. The hypothesis that the inclusion of model uncertainty according to WBI2017 results in an incorrect representation of the underlying physical processes is further analysed for several case studies in the upper river area and the lake area. According to WBI2017 the peak discharge at Lobith is the only stochastic variable in the upper river area apart from the model uncertainty. The most important sources of model uncertainty in the hydrodynamic model used are the calibration approach, hydraulic roughness and physical processes or morphological changes under extreme conditions. In this study a simplified physical model is set up based on normal flow equations and backwater equations. This model is able to transpose discharge to corresponding water levels for different hydrodynamic systems. Varying river schematisations and two river interventions (flood channel and retention area) are modelled to compare the WBI2017 method with a more physics-based approach. In this physics-based approach the hydraulic roughness of the main channel and/or floodplains is incorporated as additional stochastic variable for the derivation of water level frequency lines. Rivers have a dynamic behaviour where the geometry of the river varies for every branch and even within the branch. It is shown that the water level uncertainty becomes smaller for wide rivers where the water level frequency line becomes flatter. The cases where river interventions are present the water level uncertainty is bounded, because of the environment/geometry that influences the water levels. According to the physics-based method the water level uncertainties are location and discharge dependent, which are both not integrated in the WBI2017 method. The physics-based approach shows potential possibilities to include model uncertainty that represents the physical processes in a better manner. For the lake area the focus is on locations where high water levels are predominantly determined by the wind that is causing a set-up on the lake. Wind transformation, modelling of the drag coefficient and schematisation of the wind fields are for wind-dominated locations the most important model uncertainties in the hydrodynamic model used in the lake area. In this study, a simplified physical model is used that simulates an one-dimensional closed basin in which the wind causes shear stresses at the water surface that result in a water level gradient. By considering an empirical parameter of the "capped Wu" formula as additional stochastic variable the uncertainty of the drag coefficient is modelled for the physics-based method. The quantification is performed pragmatically by matching the 95 % confidence bounds of the water level for the physics-based method and the WBI2017 method. The decimate heights along a lake gets larger for locations that are further away from the center of gravity of the water surface, where the wind set-up is the largest. The physics-based method demonstrates that the water level uncertainty is larger for higher decimate heights and vice versa. It can be concluded that it is not valid to choose one uniform standard deviation of the water level for all wind-dominated locations, as it is done for WBI2017. Including the model uncertainty according to the physics-based method shows potential possibilities to address this problem. The physical models used provided rapid insights into system behaviour, but the findings should be verified by using more sophisticated hydrodynamic models in which the water dynamics are represented in more detail. It is recommended to include the model uncertainty by considering a model parameter in the hydrodynamic model for the upper river area and lake area as additional stochastic variable in the Hydra-models, to model uncertainty in the water level. For the upper river area the hydraulic roughness seems the best candidate and because of computational restrictions the main channel and floodplain roughness could be considered fully dependent. For wind-dominated locations in the lake area it is recommended to use an empirical parameter of the "capped Wu" formula as additional stochastic variable. In other water systems it becomes more complex, because several equally important sources of uncertainty are present. Still, the most important model uncertainty sources could considered stochastically, but computational effort would become the limiting factor.

Nonlinear Downstream Changes in Stream Power on Wisconsin's Blue River
Geography and Geology
Biological, Environmental, and Earth Sciences
Spatial characteristics of stream power are examined along four stream reaches through the 208-km2 Blue River watershed in southwestern Wisconsin. Although prevailing theoretical arguments often use spatially aggregated data and power functions derived from hydraulic geometry to suggest that stream power increases linearly downstream, analysis of stream-power trends along the Blue River's spatially connected stream pathways in southern Wisconsin shows that these pathways exhibit varying degrees of nonlinearity in the downstream distribution of stream power. In three of the four stream pathways, cross-sectional stream power and mean stream power reach maximum values at drainage areas between 10 and 100 km2 before decreasing rapidly downstream. Geomorphic and lithologic controls, which produce unusually steep channel slopes in mid-basin locations, are primarily responsible for the nonlinear downstream trends in stream power. Wide valley bottoms and gentle channel gradients occur in erodible lithologies, while resistant lithologies are associated with narrow valley bottoms and steep channel gradients. Spatial variations in drainage network evolution and past stream flow and sediment conditions also influence modern channel gradients. Downstream variations in cross-sectional stream power along interconnected pathways within the drainage network influence the quantity of post-settlement overbank sediments stored on floodplains. Greater sediment storage occurs in the headwaters and lower valleys where stream power is low, whereas little sediment is stored in mid-basin reaches with high stream power.
