Taking the lower approach channel of the Wuliting navigation lock as a case history. A two-dimensional hydrodynamic model is developed to study regulation measures, such as riverbank excavation, construction of the guild walls, dredging and adjustment of waterway regulation. The gradual optimization of water flow conditions of the typical approach channel is expounded in detail, and the recommended regulation schemes for the downstream approach channel of the Wuliting navigation lock are proposed based on the analyses above. Through the gradual optimization of the schemes, the main conclusions are as follows: ① The optimization process of the comprehensive channel regulations is a gradual process under multi constraints. Both the feasibilities of hydropower generation and flood propagation should be considered before the regulation measures of navigation are adopted, which is usually ignored; ② There should be an optimal length of the guild walls for certain approach channels; ③ The construction of a long submerged guild wall is suggested, not only appropriate for the navigation conditions but also for the hydropower generation and flood carrying capacity. It is an effective measure to remedy the poor navigational flow in approach channels of the navigation locks.

The district administrations of Mandi, Hamirpur, and Kangra have advised the people living near River Beas not to go nearby the River for their own safety as huge volumes of water has been released from Pandoh dam in Mandi district since Wednesday morning.
The water released from the Pandoh Dam of Mandi is increasing due to the continuous melting of snow from the hills. The water level started increasing due to the scorching heat in the state of Himachal Pradesh and the melting of snow on the Himalayas.
Due to this, suddenly on late Tuesday night, the water level in the dam on the Beas River in Pandoh reached the maximum level.
The River Beas starts from Beas Kund in Kulu district and flows through the districts of Kulu, Mandi, Hamirpur, and Kangra before merging into the Pong dam located near the Talwara area of the Punjab.
Engineer, Rajesh Handa of the BBMB Pandoh said that the process of releasing water from Pandoh would continue in the coming times as well. He has appealed to all the people living on the banks of the Beas River beyond Pandoh to stay alert.
He said that in view of the increase in the water level in the dam, the management has released water in the river from Pandoh Dam at around 3 am on Wednesday. Due to which the water level of the river has also increased in Mandi city and its surrounding areas.
The 76 m (249 ft) tall Pandoh Dam is an embankment dam on the Beas River. The dam was commissioned in 1977 and its primary purpose is hydroelectric power generation. Part of a Run-of-the-river power scheme, it diverts the waters of the Beas to the southwest through a 38 km long system of tunnels and channels.
The water is used for power generation at the Dehar PowerHouse before being discharged into the Satluj River, connecting both rivers.
Pandoh Lake is created by Pandoh Dam and is located about 19 kilometers upstream from Mandi on the River Beas.

The Red John pumped storage hydro project is being developed in the Scottish Highlands by renewable energy developer Intelligent Land Investments (ILI) Group.
The new pumped storage hydro project will have a storage capacity of approximately 2,800MWh and an installed power generation capacity of 450MW. It will involve an estimated investment of approximately £550m ($777.89m).
The project was granted construction and operation consent by the Scottish Government in June 2021.
Red John pumped storage hydro project location and site details
The Red John pumped storage hydro project is located approximately 14km south-west of Inverness in the Highland region of Scotland. The project site is situated within the Dores and Essich Community Council area, near the border of the Stratherrick and Foyers Community Council.
Spanning approximately 950ha, the pumped storage hydropower project site stretches across the watershed between the catchment areas of the Ness and Nairn rivers. The Loch Ness and Loch Ashie lie to the immediate west and north-east of the site respectively, while the Loch Duntelchaig lies approximately 0.7km to the east.
Red John pumped storage hydro project infrastructure
Located at the east of the site, the headpond is designed to hold approximately five million cubic metres (Mm³) of water, of which 4.9Mm³ will be used as the working volume during the project’s operation. The project will involve the development of a trench at the bottom of the headpond to allow complete drainage when required.
The headpond inlet/outlet structure will be contained within the inner side of the embankment and the trench. It will include a course screen and gates, before narrowing into the high-pressure tunnel which will connect to the power cavern. The 50m-tall, 75m-wide inlet/outlet structure will feature the inlet for the spillway as well as scour pipes and the inlet/outlet for the high-pressure tunnel. To be developed above the top water level of the headpond, the spillway inlet will transfer excess water to a vertical pipe connected to the scour pipe.
The embankment encircling the headpond will have a length of up to 1,900m and width of up to 600m, with a maximum height of 39m. The embankment crest will have a width of up to 10m and include a 5m-wide access track with a low kerb on the external side.
The embankment will mostly be a built-up earth and rockfill structure. However, the southern edge will not have a built-up embankment, instead cutting into the existing ground level.
The tailpond inlet/outlet structure will be built on the southern bank of Loch Ness, in close proximity to the area where the Allt a’ Chruineachd waterway enters the loch. It will have a maximum depth of 15m within the bank of Loch Ness. The inlet/outlet structure will include an inclined screen of up to 90m wide with a screen cleaning mechanism at the top.
Waterways of the new Scottish hydro-electric project
The surge tanks will be built upstream of the powerhouse and downstream of the transformer gallery.
The high-pressure tunnel will have a length of approximately 900m and maximum diameter of up to 9m. The tunnel lining will be made of either precast concrete, steel segments or reinforced shotcrete.
The low-pressure tunnel, located between the transformer galley and the stilling basin of the tailpond inlet/outlet, will be approximately 1,700m long with a maximum diameter of up to 9m.
The spillway pipe will be buried and used for uni-directional transportation of spill water via gravity from the headpond to the tailpond.
Red John hydro project power generation
The power cavern for the hydropower project will house the powerhouse and the transformer gallery. The highest part of the cavern will be constructed approximately 200m below the ground level.
The 120m-long, up to 25m-wide and up to 50m-high powerhouse will house the generators, reversible pump turbines, switchgear, gantry crane, control room and offices.
The transformer gallery and the powerhouse will stand 50m apart from each other. The approximately 120m-long, up to 20m-wide and up to 30m-high transformer gallery will house the transformers, a gantry crane and a plant laydown area.
The Red John project is envisaged to be connected to the grid via the Knocknagael substation, located north-east of the project development site.
The proposal incorporates a high voltage (HV) cable that will be laid from the underground transformer gallery and routed through the access tunnel to connect to the substation at Compound 1, which is the main compound during the construction phase.

120’ Below Earth’s Surface: A Journey to Fix Charleston’s Deep Tunnel System
From 2002 to 2008, Hussey Gay Bell was involved in Phases II-IV leading up to the Phase V West Ashley Sewer Tunnel & Influent Pump Station. Phase II consisted of the design and construction of the $38.9 million Ashley Tunnel; Phase III consisted of the design and construction of the $48.6 million Cooper Tunnel; and Phase IV consisted of the design and construction of the $29.4 million Daniel Island Tunnel Extension.
The $50.8 million fifth and final phase of Charleston Water System’s 15-year+ sewer tunnel improvements program, replaced an existing deep tunnel from the Croghan Spur to the Plum Island Wastewater Treatment Plant (PIWWTP) located off of Harborview Road in Charleston with a new tunnel 120-foot-deep, 1.6 mile long tunnel from Albemarle Road, under the Wappoo Cut, to the Plum Island Wastewater Treatment Plant. Other improvements consisted of the construction of a new 60 MGD influent pump station, new pile-supported 48-inch force main, new 3,200-square-foot pump control building at the treatment plant, installation of near surface connection at the PIWWTP, two shaft sites and surface collection improvements in the Country Club of Charleston and along Harborview Road. The shafts consist of a 60-ft ID at PIWWTP and 20-ft ID at Croghan, both built using the caisson sinking method, and 30-in. drop pipe at Porter Gaud. The 8,300 ft tunnel was excavated with an 86-inch diameter single shield tunnel boring machine, manufactured by Southland Contracting, and supported with ribs and lagging boards.
In tandem with the design and construction of the tunnel project, Hussey Gay Bell was contracted to design the Near Surface Facilities project which addressed the redirection of “near-surface” wastewater flows from a drop shaft on the failing sewer tunnel back into the existing sewer collection system. Existing flows entering the Country Club Drop Shaft were permanently diverted back into the near-surface collection system and conveyed to the Plum Island WWTP. Gravity sewer and force main upgrades were made to accommodate the modified flow regime.
Hussey Gay Bell, in collaboration with Black & Veatch, was involved with all design and construction administration phases of the project which was constructed by the joint venture of Fort Worth, Texas-based Southland Contracting, Inc. and Roanoke, Texas-based Oscar Renda Contracting, Inc.

The new spillage route at the Bergeforsen power plant required cutting-edge engineering expertise and the seamless consolidation of different aspects of the project.
The majority of hydro-electric power plants in Sweden were built before the 1960s. Revised safety regulations and preparations for the climate change create a need for making major improvements to them. The goal is to improve their safety level clearly.
The Bergeforsen power plant, owned by Vattenfall AB and Eon Vattenkraft Sverige AB, was built in the mid-1950s and is located the most downstream of all hydro-electric power plant on the river Indal. Its tailrace channel releases the water at sea level near Timrå. The height of the backwater is 23 metres.
At Bergeforsen, Lemminkäinen has constructed a new spillage gate and related channels to complement the three existing gates. The new spillage gate increases the spillage capacity from 2,300 m³ per second to 3,800 m³ per second and improves the safety level of the power plant significantly.
The value of the project is approximately EUR 43 million and it encompasses temporary cofferdams, concrete structures for the gate systems, open pit excavation for the surge tank and a railway underpass which was used throughout the project. The project also included extensive landscaping. The popular pastime of the region, salmon fishing, has been taken into account by building a hiking route with piers next to the shaped bank made of blasted stone.
Heavy concrete structures, special excavation, mass hauling and landscaping required versatile expertise in engineering and practical execution and the consolidation of different aspects. In addition, the construction of cofferdams for an environment with high water pressure and the 50-metre deep surge tank built next to a residential area demanded solid know-how.
The gates of the Bergeforsen hydro-electric power plant were installed in August 2013. Construction started in summer 2011 and the entire project was completed in spring 2014.

A bridge as a new landmark
The new road bridge crossing the Wisłok River completed in late 2015 not only gave Rzeszów a faster way of getting across the river but also a spectacular landmark. The 480-m stay-cable bridge’s pylon towers 108.5m above the river and the storage reservoir of the city’s thermal power station. The bridge thereby forms a core piece of a 1.9-km-long road section with a dual-lane dual-carriageway profile with whose construction PORR had been commissioned in 2014.
The project’s tight schedule proved particularly ambitious. The bridge and road construction sections were to be completed within less than 15 months. Furthermore, supporting structures in the thermal power station’s storage reservoir needed to be built and the reservoir had to be secured against water outlet in the process. Strong wind presented further challenges to PORR’s fitters when working on the pylon.
Some 27,000m³ of cement concrete, more than 1,700t of steel and 1,898t of reinforcing steel were used to build the bridge.
With its two double carriageways, the stay-cable bridge connects the two sides of the Wisłok River at Rzeszów.© PORR AG

I am using Nays2Dflood to design the reduction of the peak discharge in a channel by exploiting the storage capacity of the channel. Initially, the channel is empty and with a steep slope (> 5%).
I was thinking of dams with a window in the bottom (like a gate).
for low flow the gate should drain the water. For higher flows the water would first accumulate in the channel and then flow over its top.
I am doing that now by increasing the topographic level at some sections but I can’t represent the low flow conditions
Also I tried to use a gate but not overtop flow of the gate can occur.
any help / suggestion would be most welcome


Industrial gate valve refers to the valve that the closing part (gate) moves vertically along the channel axis. It is mainly used as the cutting medium in the pipeline that is fully open or fully closed.
Generally, industrial gate valve is not used for regulating flow. It can be used for low temperature and low pressure as well as high temperature and high pressure,and different media can be applied according to the different materials of the valve. Gate valve is one of the most widely used valves. Industrial Gate valves are typically used in situations where frequent opening and closing is not required and the gate is fully open or fully closed.

Nizamabad: Sri Ram Sagar Project (SRSP) rejuvenation works that were delayed due to Covid-19 are now progressing at a brisk pace, with construction works of two of the three pump houses completed. The works on the third pump house are in the final stage and are expected to be completed by December end. Once completed, the scheme will facilitate lifting of water from Kaleshwaram Lift Irrigation Scheme to rejuvenate SRSP.
SRSP Executive Engineer Sudha Kiran, speaking to Telangana Today, said the rejuvenation scheme works were taken up at a cost of Rs 1,751 crore. “The project, which was a boon for north Telangana till the 1980s, lost its storage capacity from the proposed 112 tmc to 90 tmc due to silting,” he said, adding that the civil works, approach canal works, cistern and lead channel works were completed, while work on pressure mains and delivery mains were completed up to 90 per cent. Once these works are completed, mechanical works will be taken up and TRANSCO officials will complete the pump house sub-station.
Because of its meagre storage capacity, the project is unable to achieve the target to provide irrigation water to 14.68 lakh acres under phase-1 and phase-2. To achieve this target and provide irrigation waters to 12.45 lakh acres, Telangana Water Resource Department proposed to construct three pump houses under the SRSP rejuvenation scheme. Under this scheme, these three house pumps able to lift 60 tmc water from the Kaleshwaram project and fill the SRSP project in 69 days, through flood flow canal.
Later the cost of the project increased from Rs 1,091 crore to Rs 1,751 crore. Chief Minister K Chandrashekhar Rao had laid the foundation stone for the project on August 10th, 2017 at Sri Ram Sagar Project.
Under this scheme, the government has been constructing three pumps house. The first pump house constructed at Rampur on flood flow canal, second pump house at Rajeshwar Rao Pet in Jagityal district and third pump house at Mupkal mandal headquarters of Nizamabad district.

Hydrostatic and Submersible level transmitters Working principle
Hydrostatic and submersible level instruments use the head pressure of a fluid to infer level. It’s one of the oldest and most common methods around, and with good reason. Using pressure to measure level is a simple, reliable and for the most part cost effective solutions for a wide range of applications across many industries.
The equation to convert pressure (P) to level (L) is:
Thus, the equation for pressure (P) generated is:
𝑃 = 𝐿𝜌𝑔
L = level of fluid in metres above the sensor
P = pressure in kPa
ρ = density of the fluid in g/cm3
g = gravity, (Can be considered 9.81 m/s2 for most locations)
Example 1 - Level where pressure is known
1. Pressure (P) of 4.9 kPa
2. Fluid density (ρ) of 1 g/cm3
3. Gravity (g) at sea level = 9.81 m/s2
𝐿 =4.9/ (1 × 9.81) = 𝟎. 𝟓 𝒎𝒆𝒕𝒓𝒆
Example 2 – Pressure when level is known
1. Fluid level (L) is 0.5 metres
2. Fluid density of 1 g/cm3
3. Gravity at sea level = 9.81 m/s2
𝑃 = 0.5 × 1 × 9.81 = 𝟒. 𝟗 𝒌𝑷
1. Top mount hydrostatic level transmitter with a flexible insertion length.
2. Rigid top mount hydrostatic level transmitter for pressurised vessels.

Rygol Water Power Plant
A seven-valve steel weir with iron and concrete abutments is installed on the Rygol River. It was built where the old weir was located, destroyed in 1948. It drains excess water from the Czarna Hancza River, which drains into the Marycha River through Szlamica, as well as Lake Głębokie and the border Lake Szlama, and then flows into the Nemunas. In Rygola, on an appropriately prepared section of the Shlamitsa, a private hydroelectric power plant was erected in 1990 to supply electricity to the surrounding villages.


Maldives Transport and Contracting Company (MTCC) has said that Sh. Milandhoo Harbour Development Project is well underway.
MTCC said the fourth shipment of concrete blocks required for quay wall construction have been delivered to the site. Block installation work in ongoing, with 53% completion, MTCC added.
Scope of works for the project include 17,900cbm maintenance dredging operations, 72,938cbm new harbour basin dredging operations, 8,400cbm channel dredging operations, construction of a 583m breakwater, a 316m quay wall, a 93m revetment, a 25m groyne, construction of two bridges, construction of a jetty (130m x 2m), construction of an access platform, installation of 3,863sqm pavement, installation of harbour lights and navigational lights.
The project is valued at MVR 76.44 million.


With the Mississippi River predicted to crest at Baton Rouge, La., Jan. 18 – and possibly stay at the 17’ flood stage at New Orleans into early February – the Army Corps of Engineers opened the Bonnet Carré Spillway into Lake Pontchartrain Sunday morning.
The earliest winter flood stage in living memory prompted the earliest calendar date opening for the spillway since it was built in 1931, as part of the massive federal engineering response to the flood disaster of 1927.
Engineers invited the public to witness the opening, with cautions. “If you come out please leave your drones, kayaks, jet skis, and wading boots at home,” the Corps’ New Orleans district office posted on its Facebook page.
Twenty bays were opened in the spillway structure Sunday, with 10 more to be opened Monday. The spillway is used in effect as a relief valve, to hold the river flow at 1.25 million cu. ft. per second in flood stage.
For two weeks the Corps has been preparing river interests about its planned response to historic river levels coming from weeks of rain storms, with 10” to 15” above-average rainfall, across the upper river watershed. Col. Rick Hansen, the New Orleans District commander, met last week with river communities to talk about possible impacts in floodways and the Atchafalaya River basin.
It appears the river crest on the lower Mississippi River this week can be managed without opening the Morganza Control Structure, according to new data and modeling, said Maj. Gen.Michael Wehr, commanding general, U.S. Army Corps of Engineers Mississippi Valley Division.
“The latest information indicates that theriver crest can be safely passed through South Louisiana without operation ofthe Morganza Control Structure,” Wehr said.
That means there will not be an additional diversion into the Atchafalaya Basin, but high water still will be significant there, the Corps says. Water levels for the basin are expected to reach 20’ around Jan. 17 at Butte Larose, and 8’ around Jan. 21 at Morgan City.
The Morganza Spillway in Pointe Coupee Parish Control Structure is designed to be activated when the river reaches 57’ at the structure, and when flow is forecasted at 1.5 million cu. ft. per second and rising. That 57’ river height is expected Jan. 15, but the flow is projected to be 1.44 million cu. ft. per second two days later, within the design capacity for Mississippi River levees to hold between the Morganza andthe Bonnet Carré Spillway.

Through the construction of the pumped storage power plant Reisseck II, VERBUND is not only investing in the expansion of renewable energies but - in connection with the existing power plants Malta and Reisseck - is also creating one of Europe's most efficient hydropower plant groups in Carinthia's Möll Valley.
The high Alpine project area for the pumped storage power plant Reisseck II is located in Mühldorfer Graben at a height of up to 2,300 metres (m) where the Great Mühldorfer Lake will later function as an upper basin. The cavern power plant Reisseck II will be erected 1,585 m above sea level in the mountain and equipped with two powerful pump turbines.
Similar to a normal storage power plant, Reisseck II will produce peak electricity in high demand periods, whereby water will be transported via a works water channel from Great Mühldorfer Lake to the two turbines that drive the generators. The processed water will run into a lower basin.
Both of the machines units in the mountain can be switched to pump operation, whereby the generators will then function as motors and the turbines will pump the water from the lower basin back up to the upper basin. Pump operation will take place during the day when the European grid is carrying more electricity than is required by the consumers. Energy which, for example, comes from the large wind farms or the Danube power plants can be saved in the form of pumped-up water. The pumped storage power plant Reisseck II will therefore function as a "green battery" in the Alps. The power plant will have a capacity of 430 megawatt (MW), both in turbine and pump operation. This corresponds to the electricity generating capacity of approximately 200 wind turbines.
On completion of the rock cavern for the power plant in 2011, the boring of the works water channel to Great Mühldorfer Lake commenced in the first half of 2012 with an 880-ton (t) and 220 m tunnel boring machine. The assembly work on Austria's largest power plant construction site commenced in summer 2012. 300 experts are currently working on this high Alpine site. The newest VERBUND pumped storage power plant Reisseck II will be commissioned in 2014. The total investment volume amounts to € 385 million.

In this thesis, an idea to use a wind pumped storage system to pump water from a lower reservoir to an upper reservoir and use it to reduce the construction size of a new reservoir or to increase electricity production in a hydropower plant, is presented. Instead of using a wind turbine to produce electricity to drive the pumps, a shaft is proposed to connect the wind turbine and the pumps. A profitability assessment is performed for the reservoir reduction and the electricity production. A wind pumped storage system for a hydropower plant with shaft driven pumps is not widely utilized today. Capital cost estimates and a profitability assessment reveal the feasibility of field usage.


The previously-calibrated application of the Full EQuations (FEQ) model of one-dimensional, unsteady flow to a 30.7-mile reach of the Fox River in northeastern Illinois was verified with discharge, stage, and dye-transport data collected during a 12-day period in October-November 1990. The period included unsteady flow induced by the operation of a sluice gate dam located at the upstream end of the reach. The model flow field was input to the Branched Lagrangian Transport Model (BLTM) for the simulation of dye transport. The results of the FEQ and BLTM model simulations are compared with the measured data and sensitivity analyses of the model parameters for this application are presented.

Media Release Mikany Dam 23 January 2020
Mikany Dam upgrade begins
Smithton, Stanley and Irishtown will soon have greater water surety into the future as TasWater commences its Mikany Dam upgrades.
The dam, built in 1972, is fed by the Deep and Muckeye Creeks catchment and is the main source of water for the communities connected to the TasWater network.
“At the time, the construction of the dam adhered to dam regulations but now an upgrade is needed to provide greater water security for the region,” TasWater Project Manager for the Capital Delivery Office Colm O’Sheehan said.
Northern Tasmanian construction company Gradco has been selected to undertake the Mikany Dam upgrade project, with site preparation set to commence in February.
“During the time of construction, the dam will be shut from the public for 18 months,” Colm said.
“Public access to the dam must be restricted as the dam transitions into a construction site.”
Water supply to the Circular Head township will not be affected, during and post construction. Once complete, the dam will not only guarantee supply into the future, but also improve its flood capacity.
“Currently, spillway at Mikany has the capacity of outflow during a one in one-hundred-year Annual Exceedance Probability (AEP) flood event. “
“Once complete, the Mikany Dam capacity will be improved to a one in ten-thousand-year flood event, complying to recent Australian national dam safety standards.”
“The inundation area of the lake will not be increased as part of the upgrade to protect the natural
environment surrounding the lake.”
Weather depending, the project is expected to be completed by the end of August 2021.
