Tyee Lake 60' above year-ago water levels
October 10, 2019
The water level at Tyee Lake was at 1,344.9 feet on Sept. 30, which is roughly 60 feet higher than it was this time last year.
As part of the Southeast Alaska Power Agency, Tyee Lake dedicates its power to Petersburg and Wrangell, while Swan Lake produces power for Ketchikan. While the 1,345 foot water level is lower than the norm for Tyee Lake, it is still higher than the 1,285 foot water level in September 2018, said Petersburg Borough Utility Director Karl Hagerman.
If water were to stop flowing into Tyee Lake and the hydro plant had to produce power with the 1,345 feet of water it has n...

Flow model of the Hudson River estuary from Albany to New Hamburg, New York
A one-dimensional transient-flow-simulation model was developed to represent a 76-mile reach of the tidal Hudson River between Albany and New Hamburg. In this reach, the direction of flow reverses four times daily as a result of tidal influence; this produces complex current patterns and retards the rate at which the river can flush out pollutants. In the model, the reach studied is treated as two subreaches to incorporate differences in channel conditions and to simplify model calibration.
This report includes all stage (water-level) and discharge data that were used to calibrate and verify the model and compares the model results with measured data. The model accurately simulated observed flows, but further calibration based upon additional flow measurements would improve simulation of the flow magnitude and phasing of the tide reversal under low-flow conditions. The model can be used to calculate instantaneous stage, velocity, and discharge for any location in the reach and can also be used to calculate net volume flux between tide reversals.

The segmental Muskingum method,the Muskingum-Cunge (MC) algorithm with variable parameters and the Muskingum-Cunge-Todini (MCT) variable parameter method which reflecting the shape and hydraulic characteristics of the river cross-section were respectively used to study channel flow confluence for the Yuanling station-Wangjiahe station section inYuanshui Basin. The application effect of the routing method with distributed parameters in real river channel is discussed. The results show that the segmental Muskingum method,MC algorithm and MCT variable parameter method can all simulate pushing and tampering of flood in the river channel with high simulation accuracy,and the deterministic coefficients of MC algorithm and MCT variable parameter method are more accurate and stable than segmental Muskingum method. The MC algorithm and MCT variable parameter method improve the parameter characteristics of segmental Muskingum method well,and the MCT variable parameter method solves the problem of the inconsistency between the storage capacity and the steady state of MC algorithm. On the whole,the three methods have strong adaptability and reliability for flood frocast,and provide a new method for real-time flood forecast.

We recently used a single hydraulic model early in the design process of our River Bain project, to allow two strands of work to be undertaken simultaneously. This reduced the risk of one design element impacting on another, in effect the flood risk modelling and assessment was undertaken as part of the hydraulic design. This approach led to cost savings for the client since only one model was used for the design and flood risk assessment processes.
The River Bain in Lincolnshire, where we have applied this approach, has been successful in securing planning permission for a scheme to create a new chalk stream channel, thanks to our work. The large stretches of the River Bain were culverted under farmland in the 1950’s which lead to a loss of valuable chalk stream habitat. Working for the Lincolnshire Chalk Streams Project we have taken the scheme from feasibility to detailed design, and through planning.
The creation of a 1D hydraulic model was used to assess the risk of silt deposition at low flows, channel stability under medium to high flow conditions and also the potential impact of the restoration on flood risk.

The Mustinka River (JD #14) experiences widespread flooding caused by spring snowmelt runoff events. Inadequate capacity and snow blockages cause massive backups of flood water and significant breakouts near the project. These breakouts flow overland, contributing to peak flows along the Rabbit River while overtopping roads, washing out bridges and culverts, eroding fields, and threatening rural homes.
The Project includes a three-square mile impoundment and rehabilitation of the Mustinka River that functions as a bypass corridor, and consists of ten major design features:
- An approach channel
- Impoundment inlet structure
- Impoundment inlet channel
- Impoundment levees
- Outlet structure/primary spillway
- Auxiliary spillway
- Two earthen overflow spillways
- Bypass inlet structure
- Bypass corridor channel
- Realignment of Traverse County Ditch No. 35.
The existing JD #14 channel leading to the impoundment will be widened between Minnesota State Highway 9 and the impoundment inlet. This segment of ditch will become the approach channel to the impoundment and its improved capacity will allow for greater efficiency in delivering floodwaters to the Project, thereby reducing breakouts along this corridor and upstream.
After decades of project development, this project for the region is currently under construction and is anticipated to be completed in 2026.

Design and Analysis of a Positive-Drive Double-Piston Synchronous Gentle Pump
The paper presents the design and analysis of a novel positive-drive double-piston synchronous gentle pump which targets stress-sensitive fluids. The pump consists of two pistons, which rotate in a synchronized manner inside a circular channel with rectangular cross section. Each piston is positively driven by an external servomotor, and the motion of the two servomotors is synchronized by a microcontroller. Analytical modeling of the flow field in the suction and in the compression channels of the pump result in a set of analytical expressions, which allows estimating the torque, power and hydraulic efficiency of the pump. Computational fluid dynamics (CFD) software was used to verify the analytical results.

Stensea research project
In the course of the energy transition, suitable energy storage systems are increasingly needed in Germany. To this end, the Fraunhofer Institute's Stensea (Stored Energy in the Sea) research project is investigating a novel system for an underwater pumped storage power plant and testing it in model trials. The operating principle is similar to that of conventional pumped storage power plants. A hollow concrete sphere with an integrated pump turbine is installed on the seabed as the lower reservoir. The surrounding sea represents the upper reservoir, with the pressure difference corresponding to the head of a conventional pumped storage power plant. When energy is needed, a valve is opened and water flows into the hollow concrete sphere, driving the turbine to generate power. If excess energy is available, the water is pumped out of the cavity against the water pressure. In this way, the energy storage system is charged. In cooperation with the research facility, HOCHTIEF developed and built a functional model and successfully tested it in Lake Constance. The main challenge was to cast a three-meter sphere. Following the successful test in Lake Constance, the next stage will be to test a concrete sphere three times as large in the sea, which will then be able to store around 50 to 100 times as much energy.
- Successfully completed model test 2016-2017


The project entailed the construction of a new combi-piled quay structure as well as the extensive rehabilitation of the severely voided fill material behind the old quay wall.

Integrated flood forecasting and management system in a complex catchment area in the Alps—implementation of the MINERVE project in the Canton of Valais
A complex hydrologic-hydraulic model has been developed for the Upper Rhone River basin in Switzerland. It is currently operational in the Canton of Valais for real-time flood forecasting and management, providing automatic warnings to the crisis cell of the Canton as well as proposing preventive emptying operations of dam reservoirs to reduce potential flood damage. The system is connected with a database for real-time data transfer and a website has been created to provide information for flood management, such as warning levels, hydrological forecasts at the main control points of the Rhône River and its tributaries, precipitation forecasts over the whole basin, snow cover state and reservoirs water levels. Besides, a hydrological call center has been established for supporting the crisis cell during risked event situations.

ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, is closely monitoring water levels at its Red River of the North reservoirs. Below average precipitation and drought conditions continue to impact reservoir levels and discharges. Recent scattered precipitation in the basin has generally kept the pool elevations level.
The pool level at Lake Traverse, behind Reservation Dam, near Wheaton, Minn., is within the summer target level (elevation 976 to 977 feet), which is the level maintained for water supply, environmental and recreational benefits. The lake remains low for this time of year compared to recent years. Current pool level is 976.0 feet, and the gates remain closed (no water is being released).
The adjacent Mud Lake, behind White Rock Dam, is 0.9 feet below its summer target level of 972 feet. Current pool level is 971.1feet, and the gates remain closed.
The pool level at Orwell Dam, near Fergus Falls, Minn., is within the summer target level (elevation 1,063.5 to 1,064.5 feet). Current pool level is 1,064.1 feet and the release from the dam is estimated at 100 cubic feet per second. The Corps will maintain a minimum release of 80 cfs, while the pool level remains above 1,060 feet.
At Baldhill Dam, near Valley City, N.D., Lake Ashtabula is at the summer target level (elevation 1,265.8 to 1,266.2 feet). Current pool level is 1,266.1 feet, and the release is approximately 30 cfs. Conditions continue to be monitored to determine if additional release reductions are needed. Minimum release is 13 cfs.
At Red Lake behind Red Lake Dam, near Red Lake, Minnesota, the pool has fallen below the summer target level (elevation 1,174 feet). Current pool level is 1,173.8 feet, and the release is approximately 100 cfs. The Corps will remain at this release rate while assessing conditions and confirming municipal water supply and ecological needs.
At Homme Dam, near Park River, N.D., the pool level is near the summer target level (elevation 1,079.8 feet). Current pool level is 1,079.7 feet, and the Corps is not currently releasing water.
Current and historical lake levels and releases can be accessed at www.mvpwc.usace.army.mil or water.usace.army.mil. All Corps reservoirs are operated in accordance with detailed water control manuals to ensure the system performs as designed.

"The important work to be done under this contract will greatly improve the seismic stability of this facility which ensures public safety," said Reclamation commissioner Michael Connor. "Under Reclamation’s Safety of Dams Program, upgrading older facilities which pre-date current seismic design standards continues to be a priority."
Under this contract, a large excavation on the downstream side of the dam will remove loose and liquefiable foundation soils, and the excavation will be refilled with dense compacted materials. In addition, a large stability berm will be constructed on the downstream side of the dam; the dam’s crest will be raised three feet; and a second stability berm will be added on the upstream side of the dam. The work is scheduled to take place between October 2011 and winter of 2013.
Prior field investigations at Echo Dam indicated that the foundation soils underlying both the dam and spillway are potentially liquefiable during a substantial earthquake, which could cause the dam and spillway to deform. A second contract to modify the spillway is scheduled to be awarded in September 2012. The entire seismic modification project is scheduled to be completed by the end of 2014.
Echo Dam is a 158-foot high zoned earthfill structure on the Weber River, located one mile upstream from the town of Echo and 42 miles southeast of Ogden, UT. Part of the Weber River Project, Echo Dam was constructed between 1927 and 1931 to help supply supplemental irrigation water to approximately 109,000 acres of land west of the Wasatch Mountains. Echo Dam is operated by the Weber River Water Users Association.
Local traffic and nearby citizens may be affected when the work begins. Reservoir releases will occur as usual and water levels will fluctuate normally through the spring of 2012. However, in the summer of 2012 the reservoir level will be drawn down more rapidly than normal to accommodate the work. Reservoir operations may also be affected by the spillway modification work into 2013 and 2014.

Currently readiness station exceeds 30%. Most work has focused on the structures of a diversion path, which is currently nearing completion.
Design feature Zaragizhskoy HPP is the complete absence of the dam — water is taken directly from the discharge canal Aushigerskaya power plant, and the pressure created exclusively diversion. Derivation Zaragizhskoy power plant consists of two parts — an open channel and a channel to concrete chute. The channel has a length of 1,700 meters, in 2012, it had conducted excavations in the amount of more than 1.5 million cubic meters.
The first design work on Zaragizhskoy he’s been held back in 2007. Then, the station was planned as a small hydropower plant with a capacity of 15 MW derivation presented of penstocks. However, in this type of station building is not started, and in 2010 its draft was sent back for revision institution "Hydroproject."
Specialists of the Institute proposed a number of solutions that radically changed the project — in particular, through the use of all water and replace culvert channel managed to almost double, to increase the capacity of 28.8 MW power plant. In comparison, roughly the power has Baksan hydroelectric power station.
Zaragizhskaya plant is lower degree of Lower Cherek stage. It is associated with each set of the three other stations, works as follows: the water is taken and cleared of sediment on the head node Kashhatau plant, located on the r.Cherek. passing on its derivational channel and tunnel, the water brushing up on Kashhatau hydro turbines, from which enters the derivation Aushigerskaya power plant, and after it — a derivation Zaragizhskoy HPP. Thus, all three stations are equal diversion unit is used in the purified water therein, thereby increasing their cost-effectiveness.
Offtake Aushigerskaya power plant will go directly to the diversion canal Zaragizhskoy plant whose length — 3.3 km. The channel consists of two parts — the channel length of 1.7 km, and the channel-reinforced concrete gutter length 2.6 km.
- Drawing pressure-station unit Zaragizhskoy plant
The channel ends of the pool capacity of 600 m3, which is an accumulation of water before feeding the turbines.
In the event of a sudden stop hydro pool has a bachelor discharge spillway. From the pool of three metal water pipes the water will flow into the power house, where after working for three hydroelectric generators, will be back in Cherek from a recovery channel length of 1.3 km.
Derevatsiya (gidrotehn.) — a set of structures (pipe, canal or tunnel), carrying a supply of water to the station assembly plant (summing derivation) or the diversion of water from it (abductor derivation).

Flood defence alternatives for the lower Bío Bío River, Chile
The Bío Bío River is the second largest river in Chile considering both discharge and length. The Bío Bío River flows through the second most important economical centre in Chile and it has been recently classified as one of the world's largest river systems strongly affected by fragmentation and change in flow regime, mainly due to hydropower and irrigation. The cities of Hualqui, Chiguayante, Concepción, Hualpén, and San Pedro de la Paz are located along the last 25 km of its course, and are exposed to a high flood risk due to a combination of increasing rainfall storms and the dams operation located in the upper basin. This work assessed several structural and non-structural flood defence alternatives for the lower 25 km of the river. A one-dimensional (1D) hydraulic model was used under different discharge scenarios. The results showed that storage areas and diversion canals located along the lower part of the Bío Bío River did not prove to be a suitable solution. Nevertheless, it was found that the most effective alternative implies a reservoir operation focused on storing the extra water produced by the incoming flood. Conclusions support the materialization of reservoir emergency operation protocols, as indicated in the Reglamento de Ley N°20.304, approved by Decreto de Ley 138, Chile.

- Prediction of hydrological water balances in dam reservoir water storage on long-term continuous rainfall–runoff estimation is highly important for accurate operational decision making related to sustainable water management planning, flood control and supply planning, etc. The physically based engineering model has been used conventionally, but requires a vast amount of hydrological and geographical data set for model construction. However, the data-driven model requires relatively low computational burden and shows reasonable accuracy depending on the feasible design of the predictor set. In this study, the dam inflow prediction using physically based model and data-driven model was compared. The antecedent soil moisture conditions were utilized effectively for training artificial neural network of continuous reservoir inflow modeling. The results indicated that the data-driven and physically based models had R ² values of 0.61 and 0.68, and Nash–Sutcliffe efficiency values of 0.60 and 0.66, respectively, which shows reasonable performance. Even though the dam inflow prediction results using the physically based model showed a relative superiority than the data-driven model, the difference was not high enough to diminish the advantages of the data-driven model. The data-driven model could be an effective alternative in areas of limited availability in hydrologic observations and geospatial data sets.


The project consisted of the demolition of the existing pumps, equipment and the supply and installation of a completely new pumping system for the town. We also retrofitted the existing pump station building with a completely new second storey construction on a suspended concrete slab. In addition, to this, we upgraded the raw water supply piping and constructed a new electrical building to house a new generator and electrical/controls equipment.
Value: $2.4 million

The Flood in Vrindavan
The water level in the Yamuna river has rised very high this year. Mansoon rains and dams opening caused the flood in Vrindavan. This is the biggest flood in Vrindavan since the major one of 1978.
This video has been taken as part of filming the BB Govinda Swami's video project about Vrindavan.
The flood is over now and the water level gets down back to normal. But you can see how it was at it' peak

Perseverance Dam is now full
UPDATE: Perseverance Dam flowed over the spillway at 2.05pm today for the first time in almost 10 years.
Significant rainfall in the area both yesterday and today pushed the level from 97 per cent this morning to overflowing early in the afternoon.
Perseverance Dam last spilled on February 21, 2001.
This water flows down Perseverance Creek directly into Lake Cressbrook which is currently at around 56% capacity.
Spillage from Perseverance Dam into Lake Cressbrook will accelerate the filling of Lake Cressbrook and it is anticipated that all storage dams will reach near full capacity in the near future.
Currently, the combined storage level of Toowoomba’s three dams is sitting at around 70%.
The last time dams were at this level was July 18, 2002. Cooby Dam is currently around 71% capacity.
The last time the combined dam level reached 100% was on March 21, 1999, with Cooby Dam spilling on February 5 and Cressbrook Dam on March 21 that year.
Dam levels are expected to continue to rise due to runoff and forecast showery weather over the weekend.

Authorized by the Flood Control Acts of 1936 and 1938, Mahoning Creek Lake is one of 16 flood control projects in the Pittsburgh District. An important link in a system of flood control projects, Mahoning provides flood protection for the lower Allegheny River Valley and the upper Ohio River.
Since its completion in 1941, the Mahoning project has prevented flood damages estimated to be in excess of $686 million. Mahoning has the capability to store the equivalent run-off of 4.09 inches of precipitation from its 340 square mile drainage area. When compared to the savings which have resulted the estimated construction cost of $6 million appears small.
Mahoning also stores water and releases it downstream during dry periods to improve water quality and quantity for domestic and industrial use, navigation, recreation, esthetics and aquatic life.

Brief introduction of ball type check valve:
This wear-free ball type check valve uses a rubber-covered ball as the valve disc. Under the flow of the mediums, the ball can roll up, down, left and right on the integral slideway inside the valve body to open and Close the mediums. Silencing closing, no water hammer, reliable sealing performance. The valve body adopts a full water flow channel, with large flow, small flow resistance, 50% less head loss than the swing check valve. It can be installed horizontally or vertically.
Brief introduction of swing check valve:
Swing check valve ,also known as one-way valve or non-return valve, is used to prevent the back-flow of the mediums in the pipelines. The valve that opens and closes driven by the flow force of the medium to prevent the medium from flowing back is called check valve. The check valve belongs to the automatic valve category, which is mainly used on the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents. This type of check valve should generally be installed horizontally in the pipeline.
Brief introduction of wafer butterfly check valve:
Wafer butterfly check valve consists of valve body with lifting hole, two half-round disc, torsional spring, and rubber valve seat. The disc and seat are sealed very well,so there is no leakage. There are sealing ring at the two sides of the valve body, which can guarantee the efficient sealing even without the sealing gasket.
Brief Introduction of rubber disc check valve:
Rubber disc check valve includes valve body, valve deck, valve disc,etc. With the slant design for sealing, the closing time is short, the force occurred by water hammer will be reduced. The disc is made of NBR/EPDM and steel plate pressed under high temperature, which is resistant to erosion.

The occurrence and development of the dominant unsteady flow structures in a vanless centrifugal pump impeller are revealed by the proper orthogonal decomposition (POD) method. The pressure and velocity data of four radial surfaces is selected as the variables of decomposition. The results show that this method is beneficial to the analysis of flow field when there is no strong interaction of flow structures. When the flow rate starts to decrease from the design flow rate, unstable flow phenomenon such as flow separation and wake begin to appear and develop in the impeller. The POD analysis reveals the influence of the main unsteady structures on the flow field when there is no mixed or have little interaction among flow structures. It outlines the development of flow separation near the suction side of impeller and the wake near the trailing edge as the flow rate changes. However, the flow field inside the impeller becomes more and more complex as the operation condition is far away from the design condition, which needs to be combined with other methods to better analyze the flow field.
