Flood studies and physical model tests demonstrated that the original overflow and spillway facilities at the Ogden Impounding Reservoir were unable to pass the Probable Maximum Flood (PMF) without overtopping onto the main earth embankment with a consequent risk of failure due to the destructive action of out-of-channel flows.
The main purpose of the project was to improve the overflow and spillway facilities at Holden Wood and Ogden Reservoirs allowing PMF flows to be safely routed through the Grane Valley cascade and return the reservoirs to their normal operating levels.
PaSCoE were commissioned by Eric Wright Civil Engineering to provide both permanent and temporary works design.
To provide temporary access across the existing combined spillway trapezoidal open channel required the provision of a 16m long steel bridge. The capacity of the bridge for the proposed construction loading was checked and bridge abutments, which comprised filled manhole rings, were designed by PaSCoE. The proposed settlement of the abutments was analysed in order to maintain a clearance between the underside of the bridge beams and the top of the channel walls.
A temporary crane pad of reinforced unbound aggregate was designed and certified by PaSCoE to enable the bridge to be lifted into position using a 500t mobile telescopic crane.

Dam Improvement Program
SunWater manages its dams through its dam management program, systems and processes. The dam management program includes annual and 5 yearly comprehensive inspections and comprehensive risk assessments.
While SunWater’s dams were designed and constructed to meet the relevant engineering and construction standards of the time, since that time changes have occurred to both the engineering design standards, as well as our understanding of the size and scale of flood event possible at the various dam sites.
Subsequently, as part of its dam management program SunWater dams undergo a process of continuous assessment against statutory requirements, Australian National Committee of Large Dams (ANCOLD) guidelines, and Australian and International Standards. SunWater also regularly engages industry experts to provide peer review or advice on various activities within its dam management program.
SunWater is undertaking a dam improvement program to ensure the highest level of safety for our dams is maintained.
Our dam improvement program will ensure our dams continue to be able to hold and safely release excess volumes of water during periods of extreme rainfall and satisfy modern standards.
None of SunWater’s dams pose any immediate safety risk. This improvement program is simply responding to BOM extreme rainfall projections and government and industry guidelines.
As a responsible dam owner, SunWater must respond to these projections to ensure its dams can cope with extreme weather conditions however low the risk may be. Other water authorities throughout Australia are carrying out similar dam improvements in line with these projections.
Consultation will be undertaken with communities surrounding the dams before improvement works commence.
Issues such as access and dam use implications during construction will be considered before finalising improvement plans and construction programs.
A business case will be prepared for funding of each dam improvement project and those will be reviewed on a case-by-case basis.
For further information about SunWater's improvement program, please call SunWater on 13 15 89.

Devils Gate Power Station Wikipedia
Part of the Mersey–Forth scheme that comprises eight hydroelectric power stations, the Devils Gate Power Station is the sixth station in the scheme. The power station is located below the double-arched concrete Devils Gate Dam which forms Lake Barrington. Water from the lake is fed to the power station by a 150-metre (490 ft) single penstock tunnel.
The power station was commissioned in 1971 by the Hydro Electric Corporation (TAS) and the station has one Boving Francis turbine, with a generating capacity of 63 megawatts (84,000 hp) of electricity. The station output, estimated to be 314 gigawatt-hours (1,130 TJ) annually, is fed to TasNetworks' transmission grid via an 11 kV/110 kV Siemens generator transformer to the outdoor switchyard.
Lake Barrington is a world-famous rowing venue that hosted the 1990 World Rowing Championships. The dam is 84 metres (276 ft) high. It is one of the thinnest concrete arch dams in the world.

Calculation and Control of Seepage of Hardfill Dam with Different Foundation
As a new dam type, Hardfill dam has been arisen recently. The suitable geologic condition of t Hardfill dam construction was analyzed based on considering its characteristics in this paper; it was also studied how to choose the reasonable impervious and drainage system to control the dam body and foundation’s seepage on a given geologic condition to make sure the safety of the project. On the basis of analyzing the foundation geologic conditions of many common dam types, two kinds of typical Hardfill dam foundation were put forward. The seepage field law of dam foundation was analyzed by dam foundation seepage discharge, uplift pressure and seepage gradient of some typical positions after setting reasonable impervious and drainage measures on the two kinds of dam foundations. It is indicated by the calculation results that the adaptability of Hardfill dam foundation is comparatively nice, and the safety of dam foundation can be ensured if appropriate impervious and drainage measures are adopted.

Hongshui River in S.China to be dammed in NovemberThe Hongshui River in south China will be dammed in early November to facilitate construction of the Longtan hydropower plant, which will be second only to the Three Gorges Project now being built on the middle reaches of the Yangtze River.
Long Xianjin, deputy general manager of the Longtan Hydropower Development Co. Ltd said the damming of the river will be a milestone for the Longtan project because then the project will beshifted from general digging to concrete pouring for the dam.
According to Long, the damming is taking place right on schedule and preparations have been completed.
Situated 15 kilometers away from the seat of Tian'e County in the Guangxi Zhuang Autonomous Region, the Longtan hydropower project is one of the main facilities for sending electricity from resource-rich west China to economically developed east China.
It will also help improve flood control capabilities on the middle and lower reaches of the Pearl River and will promote localeconomic development and benefit 10 million people who live in poverty-stricken areas of Guangxi and Guizhou Province.
The Longtan project will consist of such facilities as underground workshops for power generators, a ship lift and a 192-meter-high dam. It will cost 24.3 billion yuan (about 2.93 billionUS dollars) for the first phase, and will be installed with seven generators with a generating capacity of 700,000 kw each. The project's planned installed capacity will total 5.4 million kw andthe project will be able to generate 15.67 billion kwh of electricity a year.
Construction of the project began in July 2001. In accordance with the construction schedule, the river would be dammed in November 2003 and the first power generator will begin to generate electricity in July 2007.
The project will be finished around December 2009, said Long.

Project Status: Planned
Why we’re doing this
Green Square sits on a floodplain that used to be a network of wetlands and creeks.
Hazardous flooding has been a constant challenge for Green Square locals with floodwaters reaching 2.3m on Joynton Avenue during storms in April 2015.
What we’re doing
We’re planning a new stormwater drain from the corner of O’Dea and Joynton avenues to Zetland Avenue.
This work is part of new stormwater infrastructure to reduce the risk of severe flooding along Joynton Avenue.
The new drain will carry stormwater from the southern part of Waterloo and surrounding areas along Joynton Avenue to the Green Square stormwater drain.
A review of environmental factors has been completed and approved. It’s guiding us in finalising the design and determining the construction approach.

Pressure The basic definition of pressure is force per unit area. As commonly used in hydraulics and in this manual, it is expressed in pounds per square inch (PSI).
Atmospheric Pressure is the force exerted on a unit area by the weight of the atmosphere. At sea level, the atmospheric standard pressure is 14.7 pounds per square inch.
Gage Pressure Using atmospheric pressure as a zero reference, gage pressure is a measure of the force per unit area exerted by a fluid. Units are PSIG.
Absolute Pressure is the total force per unit area exerted by a fluid. It equals atmospheric pressure plus gage pressure. Units are expressed in PSIA.
Outlet Pressure or discharge pressure is the average pressure at the outlet of a pump during operation, usually expressed as gage pressure (psig).
Inlet Pressure is the average pressure measured near the inlet port of a pump during operation. It is expressed either in units of absolute pressure (psig) preferably, or gage pressure (psig).
Differential Pressure is the difference between the outlet pressure and the inlet pressure. Differential pressure is sometimes called Pump Total Differential pressure.
Vacuum or Suction are terms in common usage to indicate pressures in a pumping system below normal atmospheric pressure, and are often measured as the difference between the measured pressure and atmospheric pressure in units of inches of mercury vacuum, etc. It is more convenient to discuss these in
absolute terms; that is from a reference of absolute zero pressure, in units of psia.

NPSH of pump (net positive suction head) should be calculated/predicted in the beginning of pump sizing. The purpose is to check if the pump will work appropriately. Liquid pressure will lower right in inlet of pump impeller. If pressure reduction is lower than vapor pressure, liquid phase will change to vapor phase. The impeller rapidly collapses vapor bubbles which cause cavitation and damage.
In this post I will share you how to calculate NPSH available, which is net positive suction head calculated based on system arrangement. The value of NPSH available (NPSHA) shall be greater than NPSH required (NPSHR), which is a function of pump and to be specified by pump manufacturer.
NSPH of pump is calculated as follow:
NPSH available (ft, m) = absolute pressure (ft, m) – vapor pressure (ft, m) – line loss (ft, m) ± elevation difference (ft, m) Read More

The 27MW Dordi Khola hydroelectric project will start producing electricity by the end of April – myRepublica
KATHMANDU, March 9: An additional 27 megawatts of hydropower will be added to the national grid by the end of April this year, with the Dordi Khola Hydropower Project (DKHP) nearing the final stage of construction completion.
Munna Shakya, project manager of DKHP, said most of the construction work has already been completed and they are currently working on maintaining the infrastructure damaged by the floods of the last rainy season. “We have already completed the production test and will be producing power commercially by the third week of April,” Shakya said.
DKHP, a run-of-river hydropower project, is being developed by Himalayan Power Partner Ltd, a subsidiary of IME Group and NRN Investment Ltd. The project is the first of its kind, promoted by non-resident Nepalese.
The project was expected to be completed by August 31, 2018. However, it was delayed due to multiple causes including India’s economic blockade in 2015 and flood damage in different periods. Lately, the construction deadline for the project was extended to March 2021, a date that could not be met due to the COVID-19 pandemic.
DKHP is being constructed on the Dordi River of Lamjung District. Initially, the project was to be built for Rs 4.23 billion. However, the cost is expected to rise to Rs 4.64 billion due to delay in the construction of the project.

California American Water (CAW), the State Coastal Conservancy (SCC) and California Department of Fish and Wildlife (CDFW), the project owners, cooperatively removed the San Clemente Dam on the Carmel River, Monterey County, California. San Clemente Dam was 106 feet tall and constructed in 1921. After more than 10 years of alternatives analysis, dam removal was selected as the preferred project alternative to greatly improve fish passage conditions for the Federally-, and State-listed steelhead, and to address serious dam stability conditions. The dam removal project involved re-locating the Carmel River into the San Clemente Creek drainage and constructing a new combined channel downstream to the dam location.
In conjunction with URS/AECOM and Inter-fluve, Inc., Balance Hydrologics completed the preliminary feasibility analysis of constructing a new channel which combined Carmel River and San Clemente Creek to convey flow and sediment past the dam. Balance Hydrologics was asked to join the design team because of our unique expertise researching and using step-pools to renaturalize streams throughout California, Nevada, and Oregon.
Over the course of two years Balance Hydrologics and Inter∙fluve used field analogs in the watershed to develop an indicative channel design for the project. The indicative channel design forms part of the basis for the contract documents for the dam removal.
During the dam removal and channel construction phases Balance was retained as the owner’s representative. Our duties included review of all design submittals developed by the Granite Construction team, field inspections of channel construction, development of risk assessment and contingency planning for unforeseen construction circumstances and representing the interest and expectations of the permitting agencies and owner’s team throughout the duration of construction.

- Q:What type of check valve is the h61y-40 check valve?
- The disc type check valve is simple in structure and can only be installed on the horizontal pipe. The sealing performance is poor. Five. Check valves: Valves sliding along the centerline of the valve. Pipe type check valve is a new kind of valve. It is of small size, light weight and good processing technology. It is one of the developing directions of check valve. But the coefficient of fluid resistance is slightly larger than that of the swing check valve.
- Q:How do I install the pump outlet check valve?
- Because the check valve is easy to be damaged, therefore, the check valve shall be installed near the pump outlet, and a shut-off valve (usually ball valve or gate valve) is arranged on the top of the check valve, so that it is easy to overhaul. In order to facilitate the check valve before disassembly pressure relief, the valve itself is not equipped with a net valve, should be installed between the check valve and the shut-off valve with pressure relief valve.
- Q:What is the function of the check valve on the air compressor?
- Check valve to prevent backflow of gas compressor back to the machine in a series of problems, as followsA gas flow will lead to failure, load startup, startup process if the machine internal high pressure will cause the motor overload start, starting current of the motor will be too high, at the same time, the impact of transmission components is also very large, generally good machine will be some type of protection.Two, multiple units of the system may make the tank filled with water, resulting in the unit can not start properly.Three, because of the shutdown state, most of the air compressor unloading valve is open, so if the gas flow back, but also cause energy losses.
- Q:What does the check valve "H44Y-160" mean?
- Take a look at that JB/T 308 valve model compilation standards, which explain very clearlyH check valve, 4 flange connection, 4 spiral structure, Y is hard sealing hardfacing alloy. 160 is nominal pressure
- Q:Can the check valve be horizontally installed?
- Sure. As long as the direction of the check valve is installed, it's no problem how to install itWe can sell this, I know the user name is my phone, you go to the Advisory bar ~!
- Q:The difference between the plunger type check valve and the lift check valve
- Lift check valve is to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).Hope to be of some help to you!
- Q:The difference between backflow preventer and check valve
- In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.
- Q:Installation position of air pipe check valve
- Texture of material1. cast iron check valve2. brass check valve3. stainless steel check valve4. carbon steel check valve5. forged steel check valveCheck valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, counter flow valve and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.
- Q:Is the check valve the same?
- Same。 Call a difference; a thing. You come to our store to have a look.
- Q:Are check and check valves the same kind of thing?
- The same thing is not the same as it is

Ribbon cutting for Harpers Slough and Conway Lake projects
The St. Paul District, in partnership with the U.S. Fish and Wildlife Service, recently celebrated Earth Day with a ribbon cutting for two of its habitat restoration projects: Harpers Slough and Conway Lake.
Both projects are part of the Upper Mississippi River Restoration, or UMRR program.
The $5.3 million Conway Lake project, just upstream of Highway 82 on the Mississippi River included the construction of floodplain forests and berms created from main channel dredging stockpiles.
The project enhanced habitat, improved dissolved oxygen in Conway Lake and improved winter habitat conditions. This project restored 1,170 acres of aquatic and floodplain forest habitat.
The $2.4 million Harper Slough project, just upstream of Lock and Dam 9, near Lynxville, Wisconsin, protects existing islands and constructed additional islands using material from the backwater and main channel.
The project will slow the loss of existing islands, reduce the flow of sediment-laden water into the backwaters, reduce turbidity and increase the diversity of land and shoreline habitats.
Habitat restoration work was completed in 2017, however record flooding in 2018 and 2019 caused erosion and prevented the islands from establishing vegetation.
According to USACE, the project restored 1,680 acres of aquatic and island habitat.

EASTMANS WETLAND INLET WORKS
HOON HAY - CHCH
Another key aspect of the works at the Eastman’s Inlet was the works associated with managing water flows and ecology management. The works involved creating a temporary diversion of the Hoon Hay Stream to enable the construction of the new structure and earthworks to create the new inlet and outlet channels into the structure.
Once the new temporary stream diversion had been put in place and the section of the existing stream cut off, Dr Tanya Blakely and her team from Boffa Miskell completed fish salvage of the stream. Fish salvage was also completed on the temporary diversion channel before decommissioning once the Hoon Hay Stream could flow through the new structure.
The project's finishing touches included the construction of a gravel walking/bike track over the top of the concrete structure. Once the wider project has been completed, there will be a series of bike and walking tracks around the stormwater management ponds and structures for the wider public to utilise and enjoy.

The water level of Kaptai Lake, the largest man-made dam in Bangladesh has increased again following continuous raining in last couple of days. Fearing the flow of water from the hills, the authority of Kaptai Lake has opened all 16 Spillways of the Kaptai Dam from last evening.
Sources said the all 16 spillways of the Kaptai Dam remained open from July 12 for only 6 inches. As a result, the authority is releasing a total of 9000 CUSEC waters per second through the 16 spillways of the Kaptai Dam.
But, on Monday, the 16 spillways of the Kaptai Dam were opened 12 inches. So, the authority is releasing a total of 18000 CUSEC waters per second through the spillways of the Kaptai Dam. Sources said, the four unit of the Kaptai Hydraulic Power Station remained operative now while one unit is still inoperative.
As a result, 170 MW power is generated from the Kaptai Hydraulic Power Station as water level of Kaptai Lake has increased again now. So, a total of 24000 CUSEC waters are fallen into the river Karnaphuli per second. According to the sources, Kaptai Lake needs at least 94 Mean Sea Level (MSL) water levels for producing power from Hydro Power Station.
But, from Monday, the water level of the Kaptai Lake is108. 70 MSL water levels which are alarming for the flood. Sources said, the realizing of excess water of Kaptai Lake will be released till being the water level of the lake normal. After stopping the continuous raining, the level of water is likely to be normal again, sources added.
It may be mentioned that the power generation project was inaugurated in early 1962, with two of its three planned generators putting 80 MW of electricity into the national power grid.
The third generator of 50 MW started power generation in January 1982. A feasibility study revealed that the reservoir had a 25% higher capacity than what was originally computed. The operating data also revealed a higher value of inflow than had initially been calculated.
In order to exploit this additional potential, two more generators having 50 MW capacity each was installed in 1988. The power available from this dam has accelerated the establishment and expansion of industries in Bangladesh and has resulted in an appreciable saving in foreign exchange required for the import of manufactured goods. The power generated also permits pumping of water to achieve widespread irrigation and drainage.
