PUB, the national water agency, is embarking on new drainage improvement projects at 36 locations, adding to its on-going drainage projects at 176 locations around Singapore.
These drainage improvement projects are part of a "source-pathway-receptor" strategy to improve flood protection for Singapore, said PUB on Monday.
Besides "pathway" solutions, PUB will also implement a "source" measure - the construction of the Stamford Detention Tank, which is scheduled to start by end of this year.
Sited near the junction of Tyersall Avenue and Tyersall Road, the detention tank will help to reduce the peak flow of stormwater into the public drains and better protect the Stamford Canal catchment against floods during intense storms. With a storage capacity of about 38,000 cubic metres or 15 Olympic-sized pools, the Stamford Detention Tank will be built underground. Occupying a subterranean footprint of about 0.5 hectares, the tank will be sited directly beneath a nursery and a coach bay of the upcoming Singapore Botanic Gardens' Learning Forest extension.
Once completed in 2016, the detention tank will be able to temporarily hold excess stormwater from the drains along Holland Road, which is the upstream area of the Stamford Canal catchment. After the rain subsides, the water will be pumped back into the drains for subsequent discharge into the Marina Reservoir.
Besides the detention tank, PUB will be constructing the Stamford Diversion Canal which will divert stormwater from the upstream section of the Stamford Canal catchment to the Singapore River. The work will be carried out in phases, with two tenders to be called. The first tender will be called in the fourth quarter of 2013 and the other tender will be called in the first quarter of 2014. Work on the entire diversion canal is expected to be completed by 2017.
Under the long-term drainage upgrading of Sungei Pandan Kechil, PUB will be carrying out the detailed design in 2014, followed by the widening and deepening of the canal in 2015. In the interim, PUB has enlarged the inlet and outlet points of the culvert crossing at AYE 9.6km to improve the flow of water. The agency will also be calling a tender for the construction of a tidal gate in November this year.
Other drainage upgrading works at Alexandra Canal Subsidiary Drain "F" (between Tiong Bahru Road to Havelock Road) and Siglap Canal (between ECP to the sea) will also start in the second and third quarter of 2014 respectively.
Drainage improvement projects at 176 locations are also on-going across the island. These include works at major canals or outlet drains like Bukit Timah 1st Diversion Canal, Rochor Canal, Alexandra Canal, and Sin Ming Outlet drain / Marymount Rd Culvert.
In the last two years, PUB has completed drainage improvement projects at 90 locations. Some of these completed projects include works at Geylang River from Guillemard to Dunman Road, Bukit Timah Canal from Maple Avenue to Kampong Chantek, and upgrading of roadside drains across the island such as at Meyer Rd and Sunset Drive/Way.

Counter-turbine of Hydraulic Turbines Classification
Author: source: date: 2020-06-03 10:01:47
As hydropower generation matures today, the technology of water wheels is also developing and advancing. The main function of a water turbine is to convert water energy into mechanical energy. According to the different ways in which the runner converts the energy of the water, the turbines can be divided into two categories: impact turbines and impact turbines. However, under the two major categories, there are specific categories of turbines. Today we will introduce the classification of counter-turbine.
The water flow in the runner area of the counter-turbine is always a pressure flow that continuously fills the entire runner when it passes through the runner blade flow path. Direction, which produces a reaction force on the runner blades, driving the runner to rotate. After the water flows through the turbine, most of its kinetic energy and potential energy are converted into rotating mechanical energy of the runner.
Francis turbineThe water flow enters the runner in the radial direction from around, and then flows out of the runner approximately in the axial direction. Francis turbine has a wide range of application heads, about 20-700m, simple structure, stable operation and high efficiency. It is the most widely used modern turbine.
Francis turbineAlso known as Francis turbine, it is a type of impact turbine. It was invented by American engineer Francis in 1849. It is also known as Francis turbine, or radial axial turbine. The water flows into the runner radially from the surroundings, and then flows out of the runner approximately axially. The runner is composed of an upper crown, a lower ring and blades. The development trends in recent years are high head, large capacity, high specific speed and high efficiency.
Axial turbineThe water flow changes from radial flow to axial flow between the guide vane and the runner, and the water flow maintains the axial flow in the runner area. The application head of the axial flow turbine is about 3 ~ 80m. Axial-flow turbines are widely used in low-head and high-flow hydropower stations. According to whether the runner blade can rotate during operation, it can be divided into two types: axial flow fixed paddle type and axial flow rotary paddle type turbine. The runner blades of an axial-flow fixed-paddle turbine are fixed, so the structure is simple and the cost is low, but its efficiency will drop sharply when it deviates from the design conditions. Therefore, this type of turbine is generally used for low head, Hydropower stations with small output and small head changes. The runner blades of the axial flow paddle turbine can rotate according to changes in operating conditions, thereby expanding the range of the high efficiency area and improving the stability of operation. However, this type of hydraulic turbine requires a mechanism to operate the blade rotation, so the structure is more complicated and the cost is higher. It is generally used in large and medium-sized hydropower stations with large changes in the head and output.
Diagonal flow turbineThe water flow flows in the direction of an angle with the main axis in the runner area. The runner blades of diagonal flow turbines are mostly made in a rotatable form, with a wide high efficiency area, suitable for the water head between axial flow and Francis turbines, about 40 ~ 200m. It is a new model based on the improvement of the axial flow turbine in the early 1950s to improve the head of the axial flow turbine. Its structural form and performance characteristics are similar to the axial flow turbine, but due to its tilt The structure of the blade operating mechanism is particularly complex, and the processing technology requirements and cost are relatively high, so it is generally only used in large and medium-sized hydropower stations. At present, the application of this type of turbine is not common.
Tubular turbineTubular turbine is a horizontal shaft turbine with a flow path approximately straight. It does not have a water diversion volute, and the blades can be made into two types, fixed and rotatable. According to the different types of generators, it is divided into two types: full-flow and semi-flow.
The generator rotor of a full-flow turbine is directly mounted on the outer edge of the runner blade. Its advantage is that the flow channel is straight, the flow is large, and the efficiency is high. However, due to the high linear velocity and long circumference of the outer edge of the runner blade, rotary sealing is difficult. At present, this model has been rarely used.
Semi-turbine turbines have shaft extension, shaft type and light bulb type devices. Among them, shaft extension and shaft type are simple in structure and easy to maintain, but their efficiency is low, and they are generally only used for small hydropower stations. At present, the bulb tubular turbine is widely used. Its compact structure, good stability and high efficiency. Its generator is arranged in the steel bulb body surrounded by water. The turbine and the generator can be directly connected or can be increased. Speed device connection.The applicable head of the tubular turbine is 1-25m, which is suitable for low-head and large-flow hydropower stations. Due to its horizontal shaft arrangement and simple flow channel form, it has less civil engineering and simple construction, and is therefore widely used in the development of hydraulic resources such as rivers and tides in coastal areas. At present, the largest bulb tubular turbine with a diameter of 5.5m and a single output of 15MW has been independently developed in my country.
These are the specific classifications of impact turbines, which are turbomachinery in fluid machinery. It is very different from the impact turbine, for example, in terms of flow channel, the pressure of the water flow in the counterattack turbine is different and not equal to the atmospheric pressure, so a closed channel is required. However, in impulse turbines, there is no need to provide a closed channel.

Flooding prompts Missouri River traffic shutdown
OMAHA, Neb. (AP) — The Latest on a powerful storm system moving through the Midwest (all times local):
The U.S. Coast Guard says all traffic on the Missouri River from about 50 miles south of Omaha, Nebraska, downstream to St. Joseph, Missouri, has been shut down due to the river’s high water levels.
The order came Friday. The Coast Guard and U.S. Army Corps of Engineers also requested all river vessel operators create as little wake as possible between St. Joseph downstream to Kansas City to minimize levee damage.
Officials say the restrictions will be lifted as soon as flooding conditions improve.
The restrictions come as the river reached moderate flood stage at nearly 32 feet on Friday at Omaha, where it’s expected to crest at nearly 34 feet on Monday, according to the National Weather Service. The river is expected to crest at St. Joseph on Tuesday at just over 30 feet. Major flood stage at St. Joseph is 27 feet.

Kathmandu: Upper Tamakoshi Hydropower Project, the national pride project, is all set to produce power from Monday. Of the total 456 megawatt, the first unit of the project will generate 76 megawatt electricity, the project officials said.
Spokesperson of the Project, Dr Ganesh Neupane, said that Prime Minister KP Sharma Oli is scheduled to inaugurate the project at 4:00 pm on Monday amid a programme to be organised virtually.
The project on Sunday supplied electricity in the 220 KV transmission line from its powerhouse to Khimti meant for charging the power grid.
The power generated in the project will be supplied to Dhalkebar through New Khimti Substation and then it will be linked to the national system, Spokesperson Dr Neupane said.
With the completion of the project, a decade-long dream of Nepalis has come true.
Likewise, the second unit of the project is also expected to generate power by mid-July. There are altogether six units in the project.
In the initial days, the total cost of the project was estimated to be Rs 35 billion but the total expenditure of the project has reached almost Rs 80 billion due to fluctuation in the exchange rate of the US Dollar, interest rate, natural disasters and many other reasons.


The Rogun Hydropower Plant is being constructed on the upper reaches of the Vakhsh River in the Pamir mountain ranges, Republic of Tajikistan. The project is being developed by OJSC Rogun Hydropower Plant (HPP) on behalf of the Government of Tajikistan.
The 3,600MW power plant will have an output capacity of 13.1bn kWh, accounting for half of the country’s electrical installed capacity.
Part of the electrical output from the project will be sold to neighbouring countries, especially Pakistan, conveyed using the Central Asia-South Asia power project (CASA-1000) transmission line.
The 13.3km² reservoir created by the dam will further serve the purpose of irrigating 300,000ha of arid land and reduce sedimentation on the existing Nurek Dam, which is located 70km downstream of Rogun.
The project is estimated to require an investment of $3.9bn, and the dam is designed for an operational life of 115 years.
History of the Rogun hydropower plant
The project was conceptualised in the 1950s and 1960s by the Soviet Union, construction started in 1980 but was halted following the independence of Tajikistan. The construction works restarted in 2008 but were limited to the construction of safety-related and associated maintenance facilities.
The techno-economic assessment study (TEAS) and environmental and social impact assessment (ESIA) phase for the project were completed in July 2014 with funds provided by the World Bank.
The above phase was necessitated due to objections from the Republic of Uzbekistan, primarily on the initial design of the dam.
Design of the world’s tallest dam
The hydroelectric dam will have a crest elevation of 1,300m above sea level (masl) and measure 335m high. It will become the world’s tallest dam, breaking the record of the 300m-high Nurek dam.
Rogun will be a rockfill dam with a clay core, with a foundation level of 965masl, crest length of 660m and crest width of 20m.
The hydropower plant will be equipped with six radiaxial hydraulic turbines with a capacity of 600MW each. The powerhouse will be approximately 21m wide, 69m high and 220m long and will be situated in a cavern constructed of sandstone and siltstone.
Construction of Tajikistan’s biggest hydropower plant
The construction works will be performed under four separate contracts. The first contract involves the supply, erection and commissioning of the electromechanical equipment for the first four units, whereas the second contract involves the construction of the main dam for which $1.9bn has been earmarked.
The third contract will involve the construction of the right bank structures, including hydraulic tunnels and spillways, stabilisation works and the installation of hydro-mechanical equipment.
The fourth contract will involve the construction of the left bank structures, including the completion of underground structures such as headraces, powerhouse and tailrace, and installation of hydro-mechanical equipment.
The second contract is further subdivided into four stages and involves the construction of the pre-cofferdam, the cofferdam, the stage 1 dam and the full-height dam.
The pre-cofferdam is required for the diversion of the river and will be constructed of large blocks and random filling material. The cofferdam will be constructed of a bituminous core, while the Stage One dam will be constructed to enable early electricity generation.
Key players involved
Salini Impregilo has signed a framework agreement with OJSC Rogun HPP to serve as the engineering, procurement and construction (EPC) contractor for the project.
Salut Industrial Engineering Group has been contracted to manufacture and supply the specialised equipment, tanks and vessels for the water-turbine lubricating systems.
The TEAS for the project was prepared by a consortium led by Coyne & Bellier and including Electroconsult and Ipa Energy+Water Economics, whereas the ESIA report was prepared by Poyry Energy.

KATHMANDU, The main tunnel of the under-construction 73 Mw Madhya Tamor Hydropower Project on the Tamor River in Taplejung has been completed. The 3.7 km long tunnel of the project being constructed by Sanima Middle Tamor Hydro Power Company, a subsidiary of Sanima Hydro Group, has been completed.
Maniraj Pokharel, the project coordinator, said that the main tunnel was crossed at 11 pm last Friday (June 31). The main and challenging work of the project is the construction of the tunnel. We have finished digging the main tunnel of our project,” he said. “We consider it a great success.” He also said that 67 percent of the construction of the civil project has been completed.
He said that 90 percent of the work in the dam area has been completed. About 70 percent of the civil tarp work has been completed in the power plant. Hydromechanical and electromechanical work is yet to be done. The company said that some of the hydromechanical equipment has been imported and the rest is about to be imported.
The project is expected to be completed in the next 13 months. It is estimated that about 13 billion rupees will be spent to complete the project. 8 banks namely Nepal Investment, Krishi Bikas, Siddarth, and Lakshmi have invested in the project. Commercial banks have invested 9.5 billion rupees. After the construction of the project is completed and operational, the electricity produced will be connected to the national transmission system through the Dhungesanghu substation of the 220 kV Kosi Corridor transmission line.
The promoter company of the project is constructing a 9 km long transmission line up to Dhungesanghu. 24 towers will be built under the transmission line. Pokharel informed that the foundations of all the towers to be built along the route of the transmission line have been dug. He said that 3 towers have also been erected. With the investment of Sanima Group, the 28.1 megawatts lower Likhu and 14.3-megawatt upper Mailing projects are also under construction. 95 percent of which has been completed. Projects including 22 Mw Sanima Mai, 7 Mw Mai Cascade, and 2.6 Mw Sunkosi Sana have been completed and are in operation.


THE Zambezi River Authority has said water levels at the Kariba Dam will soon improve because of increased inflows from Mwinilunga and the Barotse plains.
The Authority’s chief executive director, Munyaradzi Munodawafa said water levels at the dam will improve in two months because of the increasing inflows.
“As a matter of fact, the water inflow from the Barotse plains has increased, making it possible to produce sufficient water to gain high levels at the power plant,” he said.
Mr Munodawafa in an interview expressed confidence on the progress with the water inflows from upstream in Mwinilunga and the Baroste plains, which was expected to be absorbed in the Kariba Dam in two months.
He said the increased inflows would generate enough water to earn the expected high levels in the power plant.
In addition, Mr Munodawafa said, two upstream reservoirs, the Devil’s Gorge and the Batoka Basin, would be constructed to stretch the water inflows to Kariba Dam for later use.
He said that as at present, power generation is at 500 megawatts, which was still okay for power production, although power was generated at 1,050 megawatts at full capacity when the water levels were normal.
At the moment, power generation was at 12 per cent as compared to 65 per cent of water current when water levels were high.
Mr Munodawafa said the Kariba Dam needed at least two seasons for it to attain its normal levels.
He said the insufficient rains had prevented the levels of water at the Kariba Dam from increasing, which in turn had led to low electricity power generation.
Meanwhile, Siavonga District Commissioner Lovemore Kanyama said it was unfortunate that some people were using social media to publish false information about the water levels at the dam.
He was reacting to information that was circulating on social media, which indicated that the dam had reached the normal height to end power cuts and that Government was merely being ineffective to allow continued load shedding.
“While people are saying this on social media, a view of dam at present clearly indicates the reality of the water levels at the dam.
“One can see some of the anti-vortex beams which are currently exposed due to low water levels in the lake,” Mr Kanyama said.
He said it was important to relay correct information to the public and not communicate falsehoods.

Summary High-viscosity liquid two‐phase upward vertical flow in wells and risers presents a new challenge for predicting pressure gradient and liquid holdup due to the poor understanding and prediction of flow pattern. The objective of this study is to investigate the effect of liquid viscosity on two‐phase flow pattern in vertical pipe flow. Further objective is to develop new/improve existing mechanistic flow‐pattern transition models for high-viscosity liquid two-phase-flow vertical pipes. High-viscosity liquid flow pattern two‐phase flow data were collected from open literature, against which existing flow‐pattern transition models were evaluated to identify discrepancies and potential improvements. The evaluation revealed that existing flow transition models do not capture the effect of liquid viscosity, resulting in poor prediction. Therefore, two bubble flow (BL)/dispersed bubble flow (DB) pattern transitions are proposed in this study for two different ranges of liquid viscosity. The first proposed transition model modifies Brodkey's critical bubble diameter (Brodkey 1967) by including liquid viscosity, which is applicable for liquid viscosity up to 100 mPa·s. The second model, which is applicable for liquid viscosities above 100 mPa·s, proposes a new critical bubble diameter on the basis of Galileo's dimensionless number. Furthermore, the existing bubbly/intermittent flow (INT) transition model on the basis of a critical gas void fraction of 0.25 (Taitel et al. 1980) is modified to account for liquid viscosity. For the INT/annular flow (AN) transition, the Wallis transition model (Wallis 1969) was evaluated and found to be able to predict the high-viscosity liquid flow pattern data more accurately than the existing models. A validation study of the proposed transition models against the entire high-viscosity liquid experimental data set revealed a significant improvement with an average error of 22.6%. Specifically, the model over‐performed existing models in BL/INT and INT/AN pattern transitions.

Ltd. of China Huaneng group to develop the preliminary design, detailed design, construction, and handover of the CNY 8.9 billion project, which also included consideration of water supply, flood control, and irrigation.
- The Longkaikou Hydropower Station is the first hydropower station in China to employ BIM technology across the entire lifecycle of the project, from project survey through design, construction, and operations.
- The 3D digital design solution shortened design cycle, supported collaboration between construction and design, and improved overall service quality, enabling the project to be completed 10 months ahead of schedule.
- PowerChina Huadong Engineering Corporation’s customization of the Bentley software platform to deliver hydropower plants now sets the Chinese standards for such projects.
A building information modeling (BIM) solution of the entire project was created using Bentley technology. The 3D design solution included geological modeling and analysis, civil engineering, and plant engineering. Longkaikou Hydropower Station is the first hydropower project in China to comprehensively utilize 3D digital design technology in all principal design areas — geology, hub, and plant — all facilitated through tailored Bentley technology. The optimized platform improved product quality and significantly reduced 3D design collision problems and inaccuracies.
Utilizing a Bentley BIM solution saved the company USD 300 million and enabled the project to be completed 10 months ahead of schedule through program optimization, saving up to CNY 1.79 billion. A complex topography and dam foundation with deep groves, rare in hydropower engineering, called for the comparison of design and construction scenarios with 3D modeling. The physical geology conditions were simulated through Bentley Map and Descartes, and optioneering methods were used to determine the optimal location and routing of the dam. Designs of the dam foundation’s excavation surface and deep grooves were conducted through MicroStation and GEOPAK. 3D digital design of the dam’s foundation surface saved CNY 194 million in engineering costs.
OpenBuilding Designer satisfied multiple system designs, including water retaining dam, flood discharge and energy dissipation, plant water inlet, dam crest layout, and more. A cooperative collaborative work platform was based in ProjectWise, streamlining communication and coordination among project disciplines and 3D modeling improved design efficiency by 40 percent. Bentley Navigator was used by the construction team to improve efficiency and minimize rework. Equipment collision rates were lowered by 95 percent and on-site design changes dropped by 80 percent with Bentley software.


The March 1 forecasts indicate the spring snowmelt runoff will be below average. Total April through July runoff in the North Platte River Basin above Glendo Dam is expected to be 693,000 acre-feet (af), which is 82% of the 30-year average.
The total conservation storage capacity of the North Platte Reservoir System is approximately 2,815,800 af. As of February 28, 2021, the combined storage content in the North Platte Reservoirs was 1,754,789 af, which is 116% of the 30-year average.
Reclamation, in coordination with Wyoming Game and Fish, has decided to cancel the spring flush this year due to higher than normal water storage levels in Glendo Reservoir and projected hydrologic conditions in the North Platte River below Gray Reef Dam.

Modeling for Hydraulic Hub Motor Drive System Based on Node Cavity Method 02-14-02-0011
This also appears in
SAE International Journal of Commercial Vehicles-V130-2EJ
A novel modeling method for the hydraulic hub motor drive system (HHMDS) is proposed to overcome the difficulty of using the complex AMESim model in the hardware-in-the-loop (HIL) test. The hydraulic pipeline model of the HHMDS is simplified by the lumped parameter approach. According to the node cavity method, a set of flow pressure differential equations is derived. These equations are used to describe the dynamic model of the HHMDS. To solve the rigidity problem of the model and improve the real-time performance of simulation, the HHMDS model is simplified with the integrated model and order reduction methods. Then, the simplified model is created through MATLAB/Simulink, and the accuracy of the modeling method is verified. In the three typical operating modes of the heavy commercial vehicle with HHMDS, the simulation results of the Simulink model and AMESim model are basically the same. At last, the model established by the Simulink is used in the HIL test. The test results are compared with the actual results to further verify the correctness of the modeling method in this article. The establishment of the new model by MATLAB/Simulink creates an accurate simulation test environment, and is convenient for the HIL test. The novel modeling method for the HHMDS is important for the study of the hydraulic hub motor drive vehicle (HHMDV).

Structure of IS ISR End Suction Pump
IS ISR End Suction Pump is mainly composed of pump body, pump cover, impeller, shaft, sealing ring, packing ring and suspension bearing components. The pump body and pump cover of the IS ISR End Suction Pump are split from the back of the impeller, which is the so-called back door structure. The advantage is that the maintenance is convenient, the pump body, the suction pipeline and the discharge pipeline are not moved during maintenance, and the rotor parts can be withdrawn for maintenance.
The casing of the IS ISR End Suction Pump (ie the pump body and the pump cover) constitutes the working chamber of the pump. The impeller, shaft and rolling bearing are the rotors of the pump. The suspension bearing part supports the rotor part of the pump, and the rolling bearing bears the radial force and residual axial force of the pump. In order to balance the axial force of the pump, most pumps are provided with sealing rings at the front and rear cover plates of the impeller, and a balance hole is provided on the rear cover plate of the impeller.
Due to the small axial force of some IS ISR End Suction Pumps, there are no seal rings and balance holes on the back cover of the impeller. The seal of the pump is composed of packing gland, shaft sleeve and packing, etc., or adopts the form of mechanical seal to prevent air intake or a large amount of water leakage. In order to avoid shaft wear, a shaft sleeve is installed to protect the shaft passing through the packing cavity. An O-ring is installed between the shaft sleeve and the shaft to prevent air intake or water leakage along the mating surface. The transmission mode of the pump is connected with the motor through the coupling. The direction of rotation of the pump, viewed from the drive end, is clockwise. The IS ISR End Suction Pump is improved on the basis of the IS type pump. There is a cooling chamber in the pump cover, and the filling part is cooled by normal pressure cold water, so that the temperature of the conveying medium can reach 120℃. In addition, this pump can also be used to transport clean water at room temperature. At this time, it is not necessary to supply water to the cooling chamber, realizing one machine with multiple functions.


The Hebgen Dam release gate is open and outflows to the Madison River were restored just before midnight on Wednesday, Dec. 1. Follow-up work is still required, but water in the river has reached normal levels.
A full fishing closure that was implemented in the upper Madison River will be lifted on Friday now that a gate at Hebgen Dam has been repaired and river flows are returning to normal.
A full fishing closure is in effect for the upper Madison River from Ennis Lake upstream to Hebgen Dam.
A malfunction at Hebgen Dam caused flows on the Madison River to drop Tuesday, stranding fish on riffles and concentrating fish in deep water. NorthWestern Energy is working to fix the dam.

Drava River: Precautionary Measures Have Made an Impact
Refilling of the Drava has begun. Bottom outlet opening in the Margaritzen storage area allowed for a sufficient retention capacity in the night time hours in the Mölltal valley.
Due to the predicted decrease in precipitation, VERBUND is beginning to refill the reservoirs of the Drau power plant chain. The power plants continue to be staffed.
In the Mölltal valley, sufficient retention capacity during night-time hours was created already yesterday afternoon, through the opening of the scour outlet at the foot of the dam in the Margaritzen reservoir. At the opening of the scour outlet, the effectiveness of the continuously redistributed sediment to Kaprun since 2011 could be felt, as the run-off water in the Möll was clean.
20,000 litres of water per second have been and continue to be pumped into the reservoir storage of Mooserboden on the north side of the Hohen Tauern in Kaprun (Salzburg). Thanks to these measures, the water level in the storage facility in Margaritze could be considerably decreased and its retention capacity until the night-time hours maintained.


Raina, Rajeev (2003-05). Development of a cell-based stream flow routing model. Master's Thesis.
This study presents the development of a cell-based routing model. The model developed is a two parameter hydrological routing model that uses a coarse resolution stream network to route runoff from each cell in the watershed to the outlet. The watershed is divided into a number of equal cells, which are approximated as cascade of linear reservoirs or tanks. Water is routed from a cell downstream, depending on the flow direction of the cell, using the cascade of tanks. The routing model consists of two phases, first is the overland flow routing, which is followed by the channel flow routing. In this study, the cell-to-cell stream flow routing model is applied to the Brazos River Basin to demonstrate the impact of the cascade of tanks on the flow over a simple linear reservoir method. This watershed was tested with a uniform runoff depth in absence of observed runoff data. A case study on Waller Creek in Austin, Texas with observed runoff depths and stream flow is used to demonstrate the calibration and validation of model parameters.

Falls Lake Water-Quality Study; Hydraulic Laboratory Investigation.
Final rept. Mar-Jul 74,
ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MISS
Pagination or Media Count:
A mathematical model was used to simulate the thermal and dissolved oxygen D.O. content of the proposed Falls Lake project and to evaluate the adequacy of the proposed multilevel intake structure for satisfying downstream temperature and D.O. objectives. The study indicated that proper operation of the proposed impoundment would result in satisfying the temperature objective. Low D.O. content values are predicted, reflecting the quality of water available for release through the intake structure and outlet works. However, reaeration of flow released through the multilevel outlet works should be sufficient to increase the D.O. content of the downstream release up to or above the desired minimum level of 5 mgliter.
