From email from Reclamation (Erik Knight):
The May 15th forecast for the April – July unregulated inflow volume to Blue Mesa Reservoir is 830,000 acre-feet. This is 131% of the 30 year average. Blue Mesa Reservoir current content is 468,000 acre-feet which is 57% of full. Current elevation is 7475.3 ft. Maximum content at Blue Mesa Reservoir is 828,000 acre-feet at an elevation of 7519.4 ft.
Based on the May forecasts, the Black Canyon Water Right and Aspinall Unit ROD peak flow targets are listed below:
Black Canyon Water Right
The peak flow target is equal to 6,400 cfs for a duration of 24 hours.
The shoulder flow target is 810 cfs, for the period between May 1 and July 25.
Aspinall Unit Operations ROD
The year type is currently classified as Average Wet.
The peak flow target will be 14,300 cfs and the duration target at this flow will be 2 days.
The half bankfull target will be 8,070 cfs and the duration target at this flow will be 20 days.
The ramp up for the spring peak operation has been paused as flows on the Gunnison River at Whitewater are already above the spring peak target flow. Flows on the Gunnison River at Delta are close to the flow level that could impact the Delta Wastewater Treatment Plant. Currently Crystal Reservoir is spilling with a total release of 5,300 cfs. Flows in the Gunnison River through the Black Canyon are 4,600 cfs.
With the projected increase in flows on the North Fork of the Gunnison River, releases at Morrow Pt Dam (which is now controlling the spill at Crystal Dam), will be reduced by a total of 1,400 cfs by tomorrow, May 19th. This should bring flows in the Gunnison River through the Black Canyon down to around 3,200 cfs. This release rate will be maintained through the weekend and may possibly continue well into next week.
This adjustment to the release plan is based on the latest forecast for river flows in the Gunnison Basin. Adjustments in Aspinall Unit release rates may be made in either direction to achieve downstream target flows or if water gets too high at points along the Gunnison River through Delta.

Flood trends and river engineering on the Mississippi River system
Pinter, N., A. A. Jemberie, J. W. F. Remo, R. A. Heine, and B. S. Ickes. 2008. Flood trends and river engineering on the Mississippi River system, Geophys. Res. Lett., 35, L23404, doi:10.1029/2008GL035987.
Along >4000 km of the Mississippi River system, we document that climate, land-use change, and river engineering have contributed to statistically significant increases in flooding over the past 100–150 years. Trends were tested using a database of >8 million hydrological measurements. A geospatial database of historical engineering construction was used to quantify the response of flood levels to each unit of engineering infrastructure. Significant climate- and/or land use-driven increases in flow were detected, but the largest and most pervasive contributors to increased flooding on the Mississippi River system were wing dikes and related navigational structures, followed by progressive levee construction. In the area of the 2008 Upper Mississippi flood, for example, about 2 m of the flood crest is linked to navigational and flood-control engineering. Systemwide, large increases in flood levels were documented at locations and at times of wing-dike and levee construction.

November 30: Three hydropower projects included in the People’s Hydropower Programme by the government with special emphasis have not made any progress as per the expectation.
The power generation date of those projects located in Rasuwa has been deferred every year. Despite repeated instructions from the Minister for Energy, Water Resources and Irrigation as well as the secretary at the ministry and Executive Director of Nepal Electricity Authority, the work of the project has not been effective.
A subsidiary of Chilime Hydropower Company is constructing 111 MW Rasuwagadhi Hydropower Project, 42.5 MW Sanjen Hydropower Project and 14.8 MW Upper Sanjen Hydropower Projects. It has become uncertain when these projects will start generating electricity.
Both the time and cost of the projects are increasing due to natural disasters and Covid-19 pandemic. Although the Executive Director of NEA Kulma Ghising has been urging the project officials to expedite the projects, there has not been any improvement.
The delay in completion of the projects constructed with public investment under the People’s Hydropower Project, has also resulted in the delay in construction of transmission lines.
Ghising has instructed the projects to complete the remaining works as soon as possible after monitoring the construction sites and holding discussings with the project officials, construction entrepreneurs, contractors and consultants.
“The construction of the main civil structures has been completed. The construction of the project with public investment should be completed as soon as possible and the investors should be rewarded,” said Ghising, adding, “The remaining works should be carried out side-by-side and completed within 7/8 months.”

The Louisiana Coastal Protection and Restoration Authority (CPRA) has awarded Traylor, as part a joint venture, the Construction Management at Risk (CMAR) Contractor Services for the Mid-Breton Sediment Diversion Project located on the east bank of the Mississippi River near Wills Point in Plaquemines Parish. The work entails construction of a river intake control structure through the Mississippi River and Tributaries levee. This project is intended to reduce land loss in the Breton Sound Basin. By diverting sediment from the Mississippi River, which is heavily sediment laden, along with fresh water into Brenton Sound, this will mimic nature’s land-building processes as it existed prior to the construction of levees.
As part of the Mississippi River Mid-Basin Sediment Diversion Program, the project is intended to build new land and provide an ongoing source of sand and mud necessary to sustain and increase the health of existing wetlands over time. The project will also serve to rebuild marsh vegetation and provide improved habitat for wildlife.
The joint venture will provide input into how the various project elements could be built, and assess cost, schedule, constructability, and risk impacts of project alternatives to enable the project team to select optimal solutions to positively affect the outcome of the project.


Pakistani PM praises Chinese and Pakistani engineers, workers for under-construction Dasu Hydropower project
Lauding the efforts of Pakistani and Chinese engineers and workers for the construction of the World Bank aided 4,320-megawatt Dasu hydropower project, Prime Minister Imran Khan has said the dam is vital for the development of Pakistan, as it will meet the country’s electricity need at a very reasonable tariff
Lauding the efforts of Pakistani and Chinese engineers and workers for the construction of the World Bank aided 4,320-megawatt Dasu hydropower project, Prime Minister Imran Khan has said the dam is vital for the development of Pakistan, as it will meet the country’s electricity need at a very reasonable tariff. Chinese engineering firms are playing key roles in the construction of the project.
The main civil contract work has been awarded to China Gezhouba Group Company (CGGC), according to the project website.
China Civil Engineering Construction Corporation (CCECC) has been entrusted with the work of relocating a highway and construction of an access road, while China Gansu International Corporation for Economic and Technical Cooperation (CGICOP) has bagged a USD 36 million contract for the construction of the project colony and associated infrastructure.
Power China is carrying out the construction of a key 132kV transmission line.
“The construction of the dam is a difficult task for which I pay tribute to all the workers, including foreign engineers,” Imran Khan said while addressing a gathering of Pakistani and Chinese engineers after visiting tunnels and other sections of the under-construction Dasu dam in Khyber Pakhtunkhwa province on Friday.
He said work on projects such as the Dasu dam should have been started a long ago to provide affordable electricity to people, Dawn reported.
The prime minister said time was not very far when the country would be able to ensure the supply of inexpensive electricity to people with the help of the Dasu hydropower project.
“Our economy has rapidly been improving and the acquisition of cheap electricity will meet the industrial and domestic needs and the latter will develop and put the country on the way to prosperity,” the prime minister said.
Earlier, the premier inspected different sections of the under-construction Dasu hydropower project and reviewed the pace of work.
Dasu hydropower project includes the construction of a 4,320MW plant on the Indus River near Dasu town in the Upper Kohistan district. The project is located around 74 kilometers downstream of the Diamer-Basha Dam, 240 km upstream of Tarbela dam, and 345 km from Islamabad.
The project is being developed in two stages by Pakistan’s Water and Power Development Authority (Wapda).
Briefing the prime minister, Wapda chairman Gen (retired) Muzammal Hussain said three more such dams with an overall electricity capacity of around 7,000 megawatts would be built downstream the Indus river in Pattan (Lower Kohistan), Thakot (Battagram) and Khair Abad (Attock).
“The Dasu dam’s first phase is going to be completed in 2025 and start supplying 2160-megawatt electricity to the national grid,” Mr. Hussain said. On the completion of its second phase in 2029, he said, the dam’s electricity production capacity would reach 4,320 megawatts.
He said work on the dam was well in progress and acquisition of the land for the construction of the dam and relevant projects and welfare schemes were already completed.
“We have been utilizing the country’s water resources in a better way to put this country on the way to prosperity and development,” said Hussain.

Using a model’s purpose to guide model updates: The case of the Mississippi Alluvial Plain aquifer
These techniques have been applied to the existing Mississippi Embayment Regional Aquifer System (MERAS) model to guide data collection and model dataset construction for the proposed Mississippi Alluvial Plain (MAP) aquifer model. The focus of the MAP model is to forecast aquifer water levels and surface-water/groundwater (SW-GW) exchange under different climatic and water-use conditions. Forecasts of interest (FOIs) simulated by the MERAS model include water levels and SW-GW exchange along major surface-water features under conditions of less recharge and increased water use. Preliminary results from the uncertainty analysis indicate streambed conductance values may better constrain uncertainty in water-levels and streamflow, which can be used to guide data collection in the field. These results will be presented and discussed in the context of data collection and model data preparation.

On 1 April 2014 Gezhouba Group was awarded the main contract to build the power station. It will be constructed in two 1,800 MW phases. When complete, it will be the largest pumped-storage power station in the world with an installed capacity of 3,600 MW. The power station will operate by shifting water between an upper and lower reservoir to generate electricity. During periods of low energy demand, such as at night, water will be pumped from Fengning Lower Reservoir up to the upper reservoir. When energy demand is high, the water is released back down to the lower reservoir but the pump turbines that pumped the water up now reverse mode and serve as generators to produce electricity. The process is repeated as necessary and the plant will serve as a peaking power plant.
The lower reservoir will hold up to 66,150,000 m3 (53,630 acre⋅ft) of water of which 41,480,000 m3 (33,630 acre⋅ft) can be used for power generation. The upper reservoir will withhold up to 48,830,000 m3 (39,590 acre⋅ft) of water of which 40,610,000 m3 (32,920 acre⋅ft) can be used for power generation. Water from the upper reservoir is sent to the underground power station down near the lower reservoir.

Geotechnical plans for the construction of Mexico City’s new General Canal drainage tunnel have been announced by the joint venture contractors.
The contract for the General Canal drainage tunnel was awarded by the national water commission Conagua earlier this year to a consortium comprised of Ingenieros Civiles Asociados (ICA) and ICA subsidiary Construcciones y Trituraciones.
An earth pressure balance tunnel boring machine will be used for excavation ahead of installation of a pre-cast concrete segmented lining. The project also includes construction of four shafts to depths of around 25m.
Construction of the 8km long and 5m diameter tunnel under the Chalco valley will start in February next year and work is expected to finish in March 2017.
The tunnel will be excavated parallel to the General Canal, from the Parada del Toro pumping station to the La Caldera pumping station.
Recent flooding around Mexico City has prompted an investment in a number of ground engineering projects, including the $MXN1.14bn (£51.4M) General Canal drainage tunnel. The tunnel forms part of a wider programme to reduce the risk of flooding in the area and to remediate the Tláhuac Xico lagoon.

Powerful Hozelock pond pump.
Summer Sale save £29.00
The Hozelock Cascade pond pump is a familiar name to many pond keepers as it has been around for a number of years. The main reasons for this pump's success are its design and versatility. The Cascade 4000 pond pump is the most powerful pump in the range boasting an output of 4,000lph, meaning it can be used to create a large pond fountain (3 displays) or run a waterfall.
In fact, as this pump has a significant flow rate, the pump can be used to power different applications at the same time. A 'T-piece' connected to the main body of the pump can be dialed up or down to direct flow to a couple of different sources.

On the afternoon of June 11, the dam project of Wudongde Hydropower Station, the seventh largest hydropower station in the world and the fourth largest in China, was completed, marking the completion of the main project of the world’s first 300-meter low-heat cement concrete super-high arch dam with a total installed capacity of 1020 Ten thousand kilowatts, the first batch of units will be put into production in July 2020.
China's Udongde Hydropower Station is the first stage of the four cascade power stations in the lower reaches of the Jinsha River. It is the backbone power source of “West to East Power Transmission”. The construction of power stations is of great significance for promoting China's energy structure adjustment, achieving energy conservation and emission reduction targets, and promoting the development of China's Yangtze River Economic Belt.
The person in charge of China Three Gorges Group said that the dam site of Wudongde Hydropower Station is located in the dry and hot valley of the Jinsha River. The river bed has complex geological conditions and harsh natural conditions. It is extremely difficult for the dam engineering to be integrated, especially the temperature control and crack prevention of concrete. In order to solve this world-class problem, the dam uses low-heat cement concrete, and implements the application of a number of independent innovations such as intelligent water supply, intelligent grouting, and intelligent spray to achieve safe, high-quality and efficient construction of the dam project.


River level continues to rise
BLACKFOOT — The water level on the Snake River near Blackfoot continues to rise as the combination of additional precipitation, snowmelt and reservoir releases adds to the water's volume.
The Snake River near Blackfoot is expected to crest at 9.34 feet early Wednesday morning before slowly subsiding through the rest of the week, according to the National Weather Service's Advanced Hydrologic Prediction Service. Action stage is 9.5 feet, with flood stage at 10 feet.
"Right now it's at 9.02 feet," Bingham County Emergency Management Director Craig Rowland said.
Rowland said when the river reaches action stage the county begins preparing for a potential flood.
Water was released from Palisades Reservoir earlier this year, increasing flows downstream on the Snake River. The U.S. Bureau of Reclamation began releasing water from Jackson Lake Dam, located upstream from Palisades Reservoir on April 9.
Jackson Lake is currently at 76 percent capacity. Palisades is 31 percent full.
Rowland said the river level will change with additional precipitation. A chance of rain exists through the rest of the week, with the most potential for rain Wednesday night through Thursday.
The water level of the Snake River, on average, typically begins to rise in March, continuing upward through May before subsiding in June. Last year, the Snake River near Blackfoot peaked at 10.35 feet on June 14, according to the National Weather Service.

UNSUSPECTING visitors could be forgiven for thinking someone has pulled the plug and accidentally drained the man-made Lake Meadowbank near Ouse. In fact, the water in the Hydro storage has been deliberately lowered two metres below its usual level to allow work to start on the replacement of nearly 60-year-old spillway gates on top of the Meadowbank Dam.
Hydro Tasmania says this important maintenance work will ensure Meadowbank can continue to generate renewable energy, protect surrounding communities from floods and keep water levels constant. Meadowbank Power Station started operation in the late 1960s and in an average year it generates 187 gigawatt-hours of hydro-electricity, enough to light up Hobart.
The power station uses water from the River Derwent, held in the Lake Meadowbank reservoir which is located between Hamilton and Ouse in the upper Derwent Valley. The spillway on top of the Meadowbank dam wall is automatically controlled by two crest gates. Each gate measures 6 x 35 metres and is controlled by 10 hydraulic cylinders. When the lake is full, these gates hold back approximately 60 million tonnes of water. They play a critical role in power generation and safety, and are due for replacement.
To allow this work to be carried out, Lake Meadowbank was lowered two metres below its usual level from January 29. In mid-March, the lake will be lowered a further four metres while Hydro Tasmania tests the new hydraulic cylinders and control system. The lake is expected to return to normal levels by May.
During works, the lake is too low for the Dunrobin boat ramp to be used and this facility has been temporarily closed. To explore alternative Hydro Tasmania sites nearby, visit www.hydro.com.au/findasite/
Main picture: Granville “Granny” Williams, of Maydena, surveying the scene at Lake Meadowbank earlier today, where the water level has been lowered by two metres.

Some sowing areas were damaged. The damage occurred in the Shaki, Ismayili, Agsu, Dashkasan regions. The Land Reclamation and Water Economy Committee reported that, though water level increased in rivers, it caused no floods. Rains in Ismayilli, Agsu, and Zardab increased the water level in the Girdimanchay River, which passes through these regions, to 80-90m3/s. Water level is normal at present as it has decreased to 18-20m3.
The water level in the Agsuchay River was 100m3 on rainy days but has since dropped to 9-20m3 now. Water level has increased in the Ganu (Alazan) River as well - it is currently flowing at 378m3/s feeds into the Mingachevir water reservoir.

Golf club development requires a new pumping station
Set in the rolling countryside of Torbay, Dartmoor and the South Hams, Dainton Park Golf Club is a stunning multi-purpose facility for sport, business and socialising.
WCI was approached by the Golf Club to design and install a replacement of the existing pump station to permit expansion of the Club House and to receive the increased foul flows associated with the planned expansion.
The proposal solution was to design and install a new pumping station to receive gravity flows from the Club House and also permit future connection of possible lodges to the south of the Club House. The new pumping station was to connect to the existing rising main which discharges to a mains gravity sewer some 500m from the Club House.
The installation works included the laying of new foul drain from the main building, decommissioning the existing pump chamber and the laying of a new foul drain from the PV-shed. The works were undertaken to allow for continuation of use of the foul drains, maintaining use of the facilities and minimizing the impact on the club’s members.
The pumping system comprises of:
- 27,000 L GRP horizontal pump tank with integral pump sump
- Duty/standby three phase submersible pumps rated for 80mm solids handling complete with pump assembly
- GRP Kiosk to be installed on concrete slab for the pump control panel

WQ full head multistage sewage submersible pump (hereinafter referred to as electric pump), which is composed of pump, seal and motor. The motor is located in the upper part of the electric pump, which is a three-phase asynchronous motor; the pump is located in the lower part of the electric pump, which is a flow channel impeller-volute structure. The mechanical seal is used between the pump and the motor, and the "O" shaped oil-resistant rubber sealing ring is used as the static seal to ensure the reliability of the electric pump. The pump adopts special sand control structure to ensure the reliability and service life of the electric pump; the lower part of the pump is equipped with guide bearings, so when the water level is low, the electric pump can be placed and operated horizontally (or tilted) according to the actual situation, but the motor is not allowed to run out of the water or invert the electric pump.
When the rated lift is more than 100m, the electric pump is equipped with a silencing check valve to avoid damage to the electric pump due to the phenomenon of water hammer during shutdown. The user can also adjust the installation angle of the bend according to the actual use situation, in order to facilitate the installation of the pipeline.
The rotor shaft of electric pump is made of stainless steel to ensure that the shaft has more reliable mechanical strength, which can effectively improve the wear resistance and corrosion resistance of the shaft, and is also convenient for the maintenance and disassembly of the impeller.
This series of electric pumps are widely used in industry, agriculture, mining, construction, municipal environmental protection and other places. They can pump liquids containing solid particles or soft solids such as short fiber, paper chips, sediment and so on, such as mud water, ash water, domestic wastewater, sewage, fecal urine and so on. They are ideal water conservancy equipment for agricultural drainage and irrigation, river pond silting and site construction, but they are not suitable for use in situations with explosion-proof requirements.

Prediction of suspended sediment yield by artificial neural network and traditional mathematical model in Mahanadi river basin, India
© 2017, Springer International Publishing AG. Estimation of sediment yield is essential towards understanding the mass balance between the ocean and land. Direct measurement of suspended sediment is difficult as it needs sufficient time and money. The suspended sediment yield depends on a number of variables, and their inter-relationships are highly non-linear and complex in nature. In this paper, soft computing-based sediment yield estimation algorithms are proposed for the Mahanadi river basin. A multilayer perceptron (MLP) artificial neural network (ANN) with an error back-propagation algorithm using historical monthly hydro-climatic data (temperature, water discharge and rainfall) was employed to predict the suspended sediment yield at the Tikarapara gauging station, which is the farthest downstream station in the Mahanadi river. The results demonstrated that water discharge and rainfall are significant controlling parameters of suspended sediment in the Mahanadi River. The comparative results show that the feed-forward back-propagation with Levenberg–Marquardt (FFBP–LM) is the best model for suspended sediment yield estimation, and provides more reasonable prediction for extremely high and low values. The performance of the sediment rating curve (SRC) model was below expectations as it produced the least accurate results for the peak sediment values, as well as overall model performance. It is also noticed that the multiple linear regressions (MLR) model predicted negative sediment yield at low values; which is completely unrealistic as suspended sediment yield cannot be negative in nature. It was also observed that suspended yield prediction by ANN was superior compared to that using MLR and SRC models. The proposed model will be beneficial for sediment prediction where estimates of suspended sediment values are unavailable.

Hyderabad-based Greenko has recently secured Rs 5,500 crore loan from Power Finance Corporation (PFC) to build India’s first off-river energy storage project in Andhra Pradesh.
The 20-year loan has been priced at 11% per annum interest and the power generator will have to start repaying the loan only after the project has been commissioned.
After commissioning, it will get a one-year moratorium during which it will not have to make any payment to the lender.
The storage project, fully owned by Greenko, is being built for Rs 7,600 crore, of which the debt component is being funded by PFC, a public sector undertaking.
The remaining funds for construction will be put in by Greenko as equity.
An off-river energy storage project involves the construction of two large water reservoirs at two ends of a gradient on a stretch of land.
During the day, the storage facility uses solar energy to pump the water from the bottom reservoir to the top.
At night the water is pumped down to generate hydro energy. The capacity of the storage facility is 1,200 megawatts.
Such storage facility exist at hydropower projects located along rivers but this will be the first to be constructed on a land mass.
The storage facility will cater to the spot market, state-owned power distribution companies and commercial customers. Commercial customers will account for less than 20% of the business.
Around the storage facility, multiple solar and wind energy projects are being developed. They could also buy storage capacity from the facility.
Greenko itself is developing around 900 megawatts of energy storage projects in the vicinity along with ArcelorMittal.


Bucket Dredger generally adopts vertical dredging (that is, along the channel direction) construction. According to different construction conditions, it can be divided into downstream dredging, countercurrent dredging, strip dredging, segment dredging, and layered dredging methods:
(1) Under normal circumstances, the grab dredger should use downstream excavation, mainly to prevent the grab from colliding with the hull. Countercurrent construction is used in areas with low flow velocity or reciprocating tidal currents;
(2) When the designed trench width is larger than the effective excavation width of the dredger, the slit dredging method shall be adopted. The principle of slitting is that the center is divided into two sides, and each adjacent two overlaps to prevent leakage digging. The maximum width of the slits shall not be greater than the effective working radius of the dredger;
(3) When the thickness of the mud layer is greater than the maximum excavation depth of the dredger grab bucket, the layered dredging method shall be adopted. The principle of stratification is that the upper layer should be thick and the lower layer should be thin, so as to improve the dredging efficiency and ensure the dredging quality;
(4) When the length of the excavation groove exceeds the excavation length that the dredger can excavate by setting the main anchor at one time, the construction shall be carried out in sections. The segment length is easy to take 60-70m.

ACO StormBrixx — Q-Brake Vortex
ACO Q-Brake is a horizontal vortex flow control unit designed to regulate stormwater flows. The design of a vortex flow control is based on the fluid mechanics principle of the ‘forced vortex’, which permits flow regulation without any moving parts.
ACO Q-Brake utilises the upstream head and discharge to generate a ‘vortex’ within the mechanism of the unit. The water is then released at a predetermined controlled rate preventing downstream flooding.
Unlike conventional products, ACO Q-Brake is less prone to blockage and permits higher flow at a lower head of water. This is because the vortex control allows an equivalent outlet size 4 to 6 times larger in cross-sectional area to be used.
Each ACO Q-Brake Vortex unit is custom built to suit the profile of the chamber. Radius fixing options remove the need for additional benching, simplifying installation and reducing cost.
