Flood Mitigation Projects
When County Executive Ball took office, there were already several projects underway that will increase the watershed's retention capacity and will improve water conveyance. With the exception of the construction and design of the Lower Main Street open space, these upstream projects already in the pipeline are continuing to move forward as scheduled at this time.
County Executive Calvin Ball selected a plan for flood mitigation that preserves six of the 10 buildings previously scheduled for demolition and takes more potential flood water off of Main Street during severe weather events. This map shows the entirety of the projects that were considered for flood mitigation, including the projects included in the county executive's flood mitigation plan.

This presentation was made at CAASE18, The Conference on Advancing Analysis & Simulation in Engineering. CAASE18 brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, to share experiences, discuss relevant trends, discover common themes, and explore future issues.
A series of four chronic animal studies was performed with Cleveland Clinic’s continuous-flow total artificial heart (CFTAH), without administration of postoperative anticoagulation. Upon explant, the blood flow paths for the pumps were clean except for varying amounts of thrombus attached to the right pump impeller. The current work focuses on using computational fluid dynamics (CFD) to identify an improved right impeller design that could reduce the potential for thrombus formation.
Transient, rotor-stator CFD (CFX, ANSYS Inc., Canonsburg, PA) analyses of the CFTAH were performed. The flow patterns near the left impeller surface, which was thrombus free, were used to gain insight into the desired flow patterns for different right impeller designs. Several right impeller design variations were evaluated including changes to the inlet design, impeller cone angle, and the blade shape. A non-Newtonian blood viscosity was used for the simulations. The key flow-related parameters evaluated included an Eulerian platelet stress accumulation (PSA) model, inward radial flow patterns, impeller shear stress, and flow residence time/local shear stress on surfaces just offset from the impeller were used to compare the different impeller designs.
The CFD results for the right impeller designs modeled revealed similar trends in the flow patterns with flow recirculation commonly occurring on the suction side of the right impeller blades. These recirculation regions corresponded well with the thrombus seen along the suction side of the impeller blades for the explanted pumps. For one explanted pump, a star-shaped thrombus formed around the impellers which was consistent with the areas of increased residence time/local shear stress. Iso-volumes of relative inward radial velocity also revealed regions of flow recirculation near the trailing edges of the impeller blades.
The CFD simulations revealed flow separation off the leading edge of the impeller blades and flow wrapping over the trailing edges of the impeller blades. Both effects causing flow recirculation on the suction side of the impeller blades. These flow separation effects were not seen around the left pump impeller. The right pump impeller flow is constrained by a cylindrical housing and a narrow flow aperture through which the flow passes to reach the right pump outlet. The aperture is used to balance the left/right pump flows and pressures. In comparison, the flow from the left impeller passes directly into the left pump volute and outlet port. We have recently identified a potentially improved design that showed reduced regions of flow recirculation and is undergoing further evaluation.

TWT was awarded the Blue Anchor Dam project in order to bring the substandard Route 30 (White Horse Pike) dam into compliance with NJDEP Dam Safety Regulations. The work was begun in early October of 2010, and construction started in 2015.
The Project involves the proposed construction of a new three-staged, semi-circular, ogee-shaped concrete spillway to replace the existing spillway, as well as to replace the currently undersized discharge culvert through the dam. To accelerate bridge construction, a precast concrete rigid frame structure was utilized. The dam crest elevation will be raised by three feet, and the design will also include a sluice gate for the low-level release of water.
The two biggest challenges will be to replace the spillway and discharge structure while maintaining the creek flow through the project site, all while maintaining two-way traffic during the busy summer months. Construction will be accomplished in two phases to meet this goal.
In order to accommodate an additional 12 feet of roadway widening, the spillway will also be relocated. Super-elevation (the banking of roadway on a curve) and 8-foot wide shoulders will be provided for, as well as stormwater management improvements that will address the increase in pavement surface.
TWT performed H&H analysis, inundation/dam break analysis, and all the necessary land surveying services on the project which included horizontal and vertical control, right-of-way delineation, field locations of structures, field topography and stream sections.

Three Gorges Dam Construction: Schedule from 1992 to 2009
The Three Gorges Dam had been planned for nearly 100 years. As early as in 1918, Sun Yat-sen, the pioneer of China’s revolution in modern times, had put forward a proposal to build a dam on the Yangtze River. In 1992, the Three Gorges Dam construction was officially approved and the preparation work started soon later. In 1994, the construction work on site began, which mainly includes the dam, hydropower station and navigation structures. In 2006, the dam was completed. It was not until 2009 that the whole project was fully completed. The construction was marked by three stages.
Schedule of Three Gorges Dam Project
Stage 3: 2004–2009, The Project Was Fully Completed as All Generating Units Were Installed.
The actual experience of raising the water level to 175 meters (191 yard) was started. Hence, the multiple roles of flood control, electricity generation, navigation and so on would be brought into full play.
The water level in the reservoir was tested to raise to the ideal height of 175 meters, which was the last acceptance check of the 3rd-stage of the Three Gorges Project.
The No.15 hydropower unit on the right bank was put into operation. It is the last set of Three Gorges Dam to generate power. So far, all of the 26 hydropower units had been run for power generation.
Sep 25th, 2007
The dam was impounded after the flood. By then, the water level would reach 145-156 meters (476 -512 feet).
May 20th, 2006
Through the hard work and good cooperation of everyone, the dam of Three Gorges Project was completed.
May 11th, 2006
The first generating unit on the right bank started to be assembled, signifying the beginning of the installation work of the 12 power-generation sets on the right bank.
April 21st–24th, 2006
During these four days, the then Chinese Premier Wen Jiabao made an inspection in Chongqing to discuss the migration problems caused by Three Gorges Dam construction.
March 29th, 2006
The final construction to close the Three Gorges Dam started.
The clearing work of the Three Gorges Dam was carried out.
All the fourteen generating sets on the left bank were put into production, which was one year ahead of schedule.
The electricity route which delivers electric power to Shanghai went into operation in Yidu City in Hubei Province.
No.8 power generation set on the left bank began to generate electricity.
July 26th, 2004
No.11 power generation set on the left bank was put into use to generate power.
July 8th, 2004
Having passed the acceptance standard, the permanent ship lock was formally opened to navigation after the trial navigation period.
Apr. 30th, 2004
No.7 power generation set on the left bank was put into production.

Spillway and Stilling Basin John Day Dam, Columbia River, Oregon and Washington. Hydraulic Model Investigation.
ARMY ENGINEER DIV NORTH PACIFIC BONNEVILLE OREG DIV HYDRAULIC LAB
Pagination or Media Count:
Two sectional models were used to check performance of the proposed spillway for John Day Dam and to develop improvements if necessary. A three-bay section of the 20-bay spillway was studied in a 141.14-scale model. A two-bay section of the 17 low bays to be used during second-step construction was reproduced in a 124-scale model. Modifications of the crest piers to reduce the danger of cavitation during unusually large spillway flows were recommended. Discharge ratings in the three-bay model indicated that capacity of the spillway was slightly greater than computed for the design flow of 2,250,000 cfs. A 185-ft-long stilling basin at elev 114 performed as well as a 210-ft-long basin at elev 118. Three 10-ft-high baffle piers produced desired flow conditions in bay 2 of the stilling basin.

There are two types: contact type, including single flange static pressure/double flange differential pressure level transmitter, floating ball type level transmitter, magnetic level transmitter, input type level transmitter, electric inner floating ball level transmitter, electric float level transmitter, capacitive type level transmitter, magnetostrictive level transmitter, servo level transmitter, etc. The second type is non-contact, which includes ultrasonic liquid level transmitter, radar liquid level transmitter and so on.
Static pressure input level transmitter (level gauge) is suitable for liquid level measurement of various mediums in petrochemical, metallurgical, electric power, pharmaceutical, water supply and drainage, environmental protection systems and industries. The delicate structure, simple adjustment and flexible installation provide convenience for users to use easily. Standard signal output modes such as 4-20mA, 0-5v, 0-10mA are selected by users according to their needs.
Using hydrostatics principle to measure liquid level is an important application of pressure sensor. The special cable with ventilation duct in the middle and special sealing technology are used to ensure the water tightness of the sensor and the connection between the reference pressure chamber and the environmental pressure, thus ensuring the high accuracy and stability of the measurement.


Since 2007, Tractebel Hydroprojekt GmbH has been planning the renewal of the traditional power plant site in Forbach for EnBW. With the preparation of the tender documents for the new lower stage, the planning services are now entering a new phase.
The new lower stage comprises the renewal of the two existing power plants Schwarzenbachwerk and Murgwerk. Both power plants are to be renovated with extensive use of the existing facilities. Both the Schwarzenbach dam and the Kirschbaumwasen reservoir will be integrated into the new plant concept without any structural or operational changes. The new waterways of the two power plants branch off from the existing moated castles and are led via inclined shafts into the new power plant cavern, where the machines of both the new Schwarzenbach and the new Murgwerk will be installed. The new lower stage will replace the existing Schwarzenbach plant with a fully-fledged pumped storage plant. In order to increase the storage volume, a cavern water reservoir with a usable volume of 200,000 m³ is excavated, which is hydraulically connected to the existing equalizing reservoir and forms a common storage volume with it. The cavern storage facility consists of a main gallery and six secondary galleries. The total length of the tunnel system is around 2,700 m.
The new Schwarzenbach plant will be equipped with a reversible pump turbine with a rated output of 50 MW. The combination with electrical full converter technology enables very short changeover times as well as variable-speed operation of the machine and thus the greatest possible flexibility of the new pump storage plant.
The new Murgwerk will be equipped with three Francis turbines with outputs of 13 MW, 5 MW and 0.8 MW (domestic machine) and will make frequent use of plants and equipment from the new Schwarzenbachwerk.
The approval procedure for the new lower stage has already been initiated. During the approval procedure, the necessary construction and assembly services, divided into 12 lots, are to be put out to tender and their placing prepared. The start of construction of the new lower stage is currently scheduled for the beginning of 2021.
Since the beginning of the year, the engineering consortium Forbach, consisting of Tractebel Hydroprojekt GmbH, Tractebel Engineering GmbH and Geoconsult ZT GmbH, under the leadership of Tractebel Hydroprojekt, has been commissioned with the preparation of the necessary tender planning and tender documents for the complex and technically demanding overall project. The engineering consortium will also support EnBW in the preparation of the awarding of the contract.

Optimal Economic Design of Diversion Structures during Construction of a Dam by Particle Swarm Optimization
Dr. Basim H. Khudair, Raghad S. Mahmood, Noor S. Sadeq
Diverting river flow during construction of a main dam involves the construction of cofferdams, and tunnels, channels or other temporary passages. Diversion channels are commonly used in wide valleys where the high flow makes tunnels or culverts uneconomic. The diversion works must form part of the overall project design since it will have a major impact on its cost, as well as on the design, construction program and overall cost of the permanent works. Construction costs contain of excavation, lining of the channel, and construction of upstream and downstream cofferdams. The optimization model was applied to obtain optimal channel cross section, height of upstream cofferdam, and height of downstream cofferdam with minimum construction costs for diversion works which is solved by PSO method using MATLAB. The optimization model was applied to prepare the optimal design graphs. It can be noticed, at any design flowrate, optimal water flow depth, bed width, and height of upstream and downstream cofferdams decrease with increase of the side-slope. Also, it can be observed, at any design flowrate, the construction cost increases with increase of the side-slope.

Pressure Loss of Turbulent Power Law Fluid Flow Between Two Parallel Rough Plates
- Author(s): Shukri, Abdullah Sahal
- Advisor(s): Xu, Guanshui
- et al.
The pressure loss of turbulent power law fluid flow between parallel plates has been theoretically analyzed. Using Prandtl mixing length theory and Van Karman similarity hypotheses for turbulent flow, we have derived a new friction factor formula that resembles previous formula for turbulent power law fluid flow in rough pipes. The new formula is also valid for the transition region between smooth and wholly rough wall turbulence.

The Folsom Dam Joint Federal Project is being undertaken to increase the spillway capacity of Folsom Reservoir in order to meet the demands imposed by an updated assessment of the probable maximum flood. The auxiliary spillway consists of an approach channel from the reservoir, a control structure, and a spillway chute and stilling basin that discharge spillway flows into the American River downstream of the existing spillway. The stability of the rock slopes upstream of the control structure and approach walls were evaluated using kinematic analyses to screen for critical geometry followed by limit equilibrium analyses of the kinematically-feasible cases to design slope reinforcement where necessary. Variability in the joint orientations was accounted for using a probabilistic analysis based on the measured scatter in orientation for each joint set. A fully three-dimensional (3D) analysis of the approach channel sidewalls, taking into account both existing and planned excavation geometry, existing and planned rock slope reinforcement, and the planned reinforced concrete approach walls, was also performed.

The Fairbairn Dam is an earth-filled embankment dam across the Nogoa River, located southwest of Emerald in Central Queensland, Australia. The Fairbairn Dam upgrade is addressing the condition of the original spillway drainage system and ground anchors that have deteriorated and are not functioning efficiently. The completed works aim to ensure improved function, adhering to the latest national engineering standards.
The dam owner and manager (and in this case principal contractor), Sunwater, required construction experts to progress this project to the construction phase.
The Bellwether team is working closely with the Sunwater project team to deliver an efficient construction management plan, staging plans, value engineering and risk management plans. Bellwether is also delivering detailed, probabilistic cost estimate and scheduling for the project to keep everything on track and is managing day-to-day construction activities.
The Bellwether team provided robust cost estimates for the applicable scope of work to allow Sunwater to progress the project to the construction phase of work. This project is ongoing and the Bellwether team is progressing this project well within a highly accelerated timeframe.


The controversial Blue Nile Dam has been opened in Ethiopia. Prime Minister Abiy Ahmed activated one of the thirteen turbines to generate power with the push of a number of buttons. “From now on, there is nothing that can stop Ethiopia,” the prime minister said. When completed, the dam will be the largest hydroelectric power plant in Africa.
The construction of the Grand Ethiopian Renaissance Dam began in 2011. The project is expected to be completed within two and a half to three years. The dam will then be able to provide 6,500 megawatts of power, more than double the current energy production in Ethiopia, a country of more than 110 million people.
Local media reported that the turbine, which is now in operation, will provide 375 megawatts of power. The dam is 145 meters high and is located in Juba, western Ethiopia, close to the border with Sudan. The costs are about 3.7 billion euros.
Tensions between the Nile countries
The project has led to tensions with Sudan and Egypt, through which the Nile also flows, due to repercussions on the water level in the river. Ethiopia uses the waters of the Nile to fill the reservoir in the dam. The lake has a capacity of 74 billion cubic meters of water.

Melamchi Project set to be completed by mid-July
The Ministry of Water Supply (MoWS) has claimed that the much-awaited Melamchi Water Supply Project will be completed by mid-July.
Issuing a white paper on Melamchi Water Supply Project (MWSP) with an aim to clarify the status of the national pride project, Minister for Water Supply Bina Magar informed that the project has achieved 95.12 per cent physical progress as of today and Kathmandu dwellers will get water supplied from the project from mid-July.
The government had released a white paper on Melamchi Water Supply Project to clarify the project’s status after Italy-based Cooperativa Muratori e Cementisti (CMC) di Ravenna abruptly terminated the project in December 2018.
Though the construction of Melamchi Water Supply Project was started more than two decades ago, the project is yet to be completed.
Tiresh Prasad Khatri, executive director of Melamchi Water Supply Development Board, said that the target has been set to bring water from Melamchi River up to Sundarijal reservoir within mid-July. The budget for fiscal year 2019-20 had also announced to complete the Melamchi project within this fiscal year.
As stated in the white paper, the Melamchi Water Supply Project will cost Rs 31.36 billion while Rs 28.13 billion has already been spent for the project so far. “Kathmandu residents have waited for the project for years. However, the project will no longer remain a dream and will be completed within this fiscal,” said Minister Magar.
The fate of the Melamchi project had been uncertain ever since CMC left the project in December 2018
After almost one year since CMC left the water project, the government had brought in a Chinese company called Sinohydro to complete the remaining works of the project in November last year. The Chinese firm has been given a deadline of 12 months to complete the works.
“We are optimistic that the project will be completed within the deadline given to the contractor,” added Magar.
Sinohydro has been assigned the works related to headworks and tunnel finishing, diversion tunnel, lining of audit tunnel and finishing touches of the tunnel. Similarly, the company is also building infrastructure related to the water intake aspect of the project and also work on improving the access road. Furthermore, Sinohydro is also responsible for the design and construction of the coffer dam, repair of the camp site and installation of flushing systems in the project.

On the 9th of march BBT SE CEO Dr. Ing. Raffaele Zurlo has officially handed over the new water conducts and related works, realised within the Brenner Base Tunnel project, to the mayor of Campo di Trens, Dr. Peter Faistnauer.
The new infrastructure consists of a new underground water conduct of approximately 7.500 metres length, in substitution of the preexisting conduct between the spring of Stockerbrunnen and the town of Trens. The works also included the construction of a new deacidification facility and a new water reservoir near the town of Trens. The water conduct, which is mostly made of ductile cast iron, guarantees constant water supply for the entire town, even in case the construction of the Brenner Base Tunnel should negatively affect the springs providing part of the water today. The town of Trens can now satisfy its water needs through the spring at Stockerbrunnen, which cannot be affected by the tunnel construction works due to its location on the far side of the valley. As an additional element to this project, the industrial area of Campo di Trens has been connected to the modernised water network of Trens, hence ensuring the necessary water pressure in case of fire.
The measures, designed by Ingenieurgemeinschaft Pardeller GmbH and realised by Wipptaler Bau, are part of the so called „environmental compensation measures” within the Brenner Base Tunnel project. The cost of this specific measure was approx. 1,098,000 Euros. Examples for further compensation measures, planned or already in work phase in the municipality, are extensive works for noise reduction along the existing railroad, restoring of natural fluvial environments, traffic calming along the main road and the design and construction of a theme trail.

Alstom has been awarded €265 million to supply power generation equipment to the Subansiri Hydro Power Project in India.
Alstom has been selected for a €265 million project with India’s National Hydroelectric Power Corporation (NHPC) for the turnkey supply of power generation equipment to the Subansiri Hydro Power Project, in Assam, India. The project will be the largest hydropower scheme in the country.
Alstom’s scope of supply for the 2000 MW power plant covers electro-mechanical equipment including turbines, generators, balance of plant, plant control and monitoring systems. The main components will be manufactured at Alstom’s newly-expanded factory in Baroda, India.
The plant is due to come into operation in 2010. Once completed, the hydro power station will increase the total power generation capacity of India by 2%.
“Alstom has more than a 30% share of world hydro power generation and we consider India to be one of the most important developing markets,” commented Philippe Joubert, President of Alstom’s Power Turbo Systems and Power Environment Sectors. “We have been investing in our Baroda factory in order to develop it into a world hub for hydro projects.”


The project that started on February 24, 2015 and whose phase one comprises the construction of an 11.8km diameter water diversion tunnel
from Maragua River to Ndakaini Dam, will be complete by March next year with the government hailing the project as one of its kind.For the first time, water will be transported underground without interfering with the general environment.
Hydropower project manager Deng Siwen informed that since the second half of last year, the spillway have been excavated, and the construction of the seepage prevention wall, the diversion tunnel
, the underground powerhouse and the tailwater tunnel have also been excavated, while 30 working faces have been opened.
The Laiban Dam project has been set, and the previous administration even began constructing the diversion tunnel
. Somehow, that project was stopped.
Suarez said if the construction resumes now, the diversion tunnel
will be finished in just one and half years.
Another possible water source is the Sumag River Diversion Tunnel
Project in Quezon province, House Minority Leader Danilo Suarez said as he has sought the completion of the project to help resolve the water crisis in Metro Manila.
The AG said the project management and the ministry reported that 10pc energy loss caused to NJHP by Kishanganga project could be compensated by a diversion tunnel
but it was not convincing justification because Pakistan lost water rights in international arbitration due to delays.
EPM is yet to regain control on the project's hydrology after a month since a land slide at Ituango's hydroelectric project site blocked the Cauca river's main diversion tunnel
causing the water level to rise prematurely in the project's dam.
The 25 percent civil works of the project has been completed as construction of access road/bridge, concrete batching plant, diversion tunnel
and spillway is in process.
The design compares the cost of sizes of diversion tunnel
against damages and delays related to over topping of Coffer Dam during monsoon.
The statistical analysis of the geologic conditions appearing in the excavation shows that the rock mass of the upper reaches of the diversion tunnel
on the right bank is thin and extremely thin-layered marble dolomite, whose length in the #3 diversion tunnel
is approximately 1,009.5 m, accounting for 68.6% of the total length.

Slovenia is well on its way with the project to build five hydro-power station in the final 50km of the river Sava. Three power stations have already been constructed in Boštanj, Blanca and Krško (photo), with works on the forth on Brežice to start today. The final power station that will complete the €250mln project will be constructed in Mokrice about 10km further downstream.
The works on the current power station are expected to be finished on the second half of 2017. The Brežice power plant’s rated capacity will be 45 megawatts, with an annual capacity of 161 gigawatt hours, while the facility will contribution 1% of the electricity produced in Slovenia annually.
Prime Minister, Alenka Bratušek, will inaugurate the launch of the construction.
Construction on the last hydro-power station facility in Mokrice is expected to begin in a year, with an estimated completion date somewhere in 2018 or 2019.


THE US$294 million Kariba Dam rehabilitation project is nearing completion, with commissioning expected next year.
The project involves reshaping the plunge pool at the foot of the six decades-old dam and refurbishment of the spillway.
A visit to the dam this Wednesday witnessed ongoing civil works at the giant dam wall built over 60 years ago.
Zambezi River Authority chief executive officer, Engineer Munyaradzi Munodawafa said the project was still within its timeframes and budget.
Engineer Munodawafa said, ‘‘Completion of the plunge pool is 2024. In terms of percentage, we are now going to 78 per cent, almost 80 actually. The total budget has not changed.’’
The Kariba Dam had a projected lifespan of 140 years, but unforeseen structural weaknesses, including a weak rock formation at its base were detected.
The rock was being eroded every time spillway gates were opened, inching closer to the dam structure and would eventually lead to the collapse of the dam wall with serious challenges for the region.
The rehabilitation works are envisaged to double the lifespan of the dam.


Equipped with electronic pressure control the JSP120 is designed for situations requiring strong constant pressure. These pumps also have stainless steel casings and precision-moulded internals. Loss of prime protection to prevent dry running. Ideal for automatic constant pressure household water supply especially with high suction lift.
