Canyon Ferry Dam is a flood control reservoir located northeast of Helena on the Missouri River. Canyon Ferry Dam is located on the main stem of the Missouri River approximately 27 miles downstream from Townsend, Montana. The dam was constructed in a narrow constriction of the Missouri River Valley, where the Big Belt Mountains and the Spokane Hills merge, approximately 68 miles downstream from the confluence of the Gallatin, Madison, and Jefferson Rivers. The project authority is the Flood Control Act, Public Law 534, 78th Congress, 2nd Session, approved 22 December 1944.
The Missouri River has cut through the older Precambrian rocks forming a canyon well suited for a dam. The dam and power plant are located at the upper end of the rock-walled canyon, about 1-1/2 miles downstream from the previously existing Canyon Ferry Dam and power plant built by the Montana Power Company. The old Canyon Ferry Dam was built in 1896 and formed a reservoir known as Lake Sewell. The old 7,500-kilowatt power plant was completed in 1898. The old Canyon Ferry Dam and power plant were dismantled prior to the completion of the new Canyon Ferry Dam and power plant with the remnants having been inundated and Lake Sewell becoming part of the new reservoir. Canyon Ferry Dam lies at the head of the reservoir created by Hauser Dam, located 15-1/2 miles downstream. The backwater of Hauser Lake, when full, raises the tailwater at Canyon Ferry Dam.
The Visitor Center features hands-on displays and excellent interpretive information on Canyon Ferry's watchable wildlife. There are displays of the Lewis and Clark Expedition and the construction of Canyon Ferry Dam. The visitor center is currently closed. Information about Canyon Ferry can be obtained from the field office across the street from the visitor center.
There are many campgrounds and day-use areas surrounding the reservoir.


Okjeongho Lake is located in Janggeum-ri and Jonsung-ri in Sannae-myeon, Jeongeup-si, and its water is from Seomjingang River Dam. The left and right of tributary of the dam are Ganjin-myeon, Imsil-gun and Sannae-myeon, Jeugeup-si. The former dam was constructed from November 1st, 1925 to December 1927, and the new dam was constructed from April 1940 to December 1965. Okjeongho Lake was formed during the construction of Unam Reservoir in 1928 in order to supply agricultural water to Honam Plain region. The Unam Reservoir was rebuilt in 1965 as the Seomjingang River Dam to expend its water capacity and for power production purposes, and Okjeongho Lake was widened with the construction of the dam. The lake used to be called and marked as Unamho Lake, or Seomjinho Lake but, now it is called Okjeongho Lake.


(Apply to : FRP double-wall tank hydrostatic leak detection)
FRP double-wall tanks are usually filled with monitoring fluid in the interstice. Normally, the monitoring fluid level should keep in the middle of the reservoir which is on the top of the tank. OKet® provides HLS-1D dual-point hydrostatic sensor which can accurately detect fluid-level changes in reservoir in high or low level change. If the brine solution seeps into the tank, lowering the level in the reservoir, the sensor triggers a low-level alarm. If an outer wall leak occurs and groundwater seeps into the tank, a high alarm is activated .
●Distinguish the leakage position (inner wall or outer wall)
●Inner wall leaks, low level alarm
●Outer wall leaks, if the groundwater level is high, high level alarm; if the groundwater level is low, low level alarm

A new flood wall along the beck at Bedford Street, which started in May, is almost complete, while the new lifting screen at the culvert at Primrose Hill is now operational.
Work is progressing ahead of schedule on the improved and raised embankment in the Newtown area, and construction has just begun on a flood wall along Duddon Walk. All the work is expected to be complete in September.
The Environment Agency is working closely with Stockton-on-Tees Borough Council, which is replacing Londonderry Bridge to allow the beck to flow more freely. It’s expected the new bridge will be ready to open in winter 2016/17.
The Lustrum Beck food alleviation scheme will reduce the risk of flooding to over 150 homes.
The Environment Agency’s Ted Thomas, Project Manager, said: “Work is progressing well on the Lustrum Beck scheme, with the new screen at Primrose Hill now operational and the flood wall at Bedford Street nearly complete.
“Work on the embankment at Newtown is well underway, and construction of a new flood wall at Duddon Walk has started ahead of schedule, so we’re hopeful much of the project will be complete by September.
“This will all tie in with the previously completed flood wall at Bishopton Road, and the replacement of Londonderry Bridge, which the council is currently working on and which should be complete in the winter.
“This overall scheme will bring long-term sustainable benefits to the community by significantly reducing the risk of flooding to over 150 homes and businesses.”
Additional work to store extra flood water in the catchment upstream of Stockton and create new habitat is likely to begin in 2017.


The Sarsang Hydroelectric Power Plant (HPP) is the largest source of energy in the NKR. The HPP has a 50-megawatt capacity and produces 90-100 million kilowatt-hours of energy per year. Local water resources support the construction of small HPPs in almost every region of Nagorno Karabakh. A program of future energy development has been elaborated, which entails the construction of eighteen small HPPs with a total capacity of around 140 MWt. If completed, this would increase the annual energy production to 460 million kilowatts per hour, and strengthen the domestic and external network of energy distribution.
Increasing the capacity of power stations and ensuring efficient energy consumption will create an opportunity to export energy abroad in the future.

Construction on a nine-month flood control project along Buchanan Boulevard is set to break ground Monday.
The $4.5 million project will alleviate excess water along the busy street, and will consist of building a storm drain pipe and a soil cement channel, according to Public Works Director Scott Hansen.
Funding will be provided by the Clark County Regional Flood Control District. Meadow Valley Contractors will be the lead company on the project.
The Buchanan Boulevard project will be the second largest of its kind since the district began working with Boulder City, according to district spokesperson Kelsey Hand. The largest was the $4.6 million Hemenway Channel in 1990.
The project will mainly consist of an underground pipe that will transfer water on Buchanan from Elm Street to El Camino Way. Upgrades to the concrete channel along Buchanan will be included.
The project will be broken down into four phases, and construction hours will take place during daytime hours, Hansen said. It is expected to be completed by June.

Radial Spillway/Tainter Gates
Most commonly used on the spillway of large dams for controlling the top water level. Can also used as a means of controlling water levels in channels. The normal method of operation is by mechanical hoist or hydraulic cylinders.
- Quick operation as they move in an arc.
- The entire water load is transferred radially through the arms to the pivots which reduces hoist capacity compared to a Wheel Gate.
- Gate bottom lip gives good hydraulic discharge profile.
- Hydraulic cylinder or rope hoist options.
- Flush side and sill sealing faces.
- Crest or culvert type.
- Gate aesthetics, visible when raised.
- Civil loads concentrated on piers.
- Long piers.


You may have noticed a fluctuation in water levels in the wetlands area alongside Horseshoe Bend Rd. These are due to construction works currently being undertaken at Ashbury and will continue from now to the end of May 2019. The works relate to the construction of a temporary drainage facility, south of the wetlands reserve, and an upgrade to the drainage pipes running under Horseshoe Bend Rd. The temporary drainage facility is to provide additional drainage capacity until the Council Sparrowvale wetland system is complete.
In order to facilitate these works it is necessary to relocate water from the wetland reserve to the temporarily storage facility. Works are on schedule and forecasted to be complete by May 2019. Once civil construction works related to drainage are complete, landscaping will commence around the wetland reserve with an anticipated completion date of December 2019.

Analysis of Performance Characteristics Predicted From Several Experimental Data and Conversion Methods for Pumps as Turbine Application Using Statistical Techniques
Keywords:Conversion method, pump as turbine, performance characteristics, statistical techniques
Different performance characteristics have been indicated when running centrifugal pumps in the reverse direction. The water flows from the discharge side of the pump to the suction side to run in the reverse direction and generate the mechanical rotational energy for the micro-hydropower plant. The current study evaluates the extent of variation of performance characteristics predicted by several experimental data from different pump-specific speeds and conversion methods. The performance characteristics discussed include the head, flow rate, efficiency and specific speed. The flow rate and head of a pump operating in pump mode divided with the characteristic of the pump operating in the reverse mode, at the best efficiency point, the resulting coefficient of determination (R 2 ) values were of 0.890 and 0.708, respectively. Also, the graph of head versus flow rate coefficients, which is a second- order polynomial function, has shown the value of R 2 of 0.954 for pump-specific speed ranging between 9 and 94 rpm. However, the pump in the reverse mode has smaller performance characteristics for efficiency and specific speed compared to the pump mode operation with R 2 of 0.966 and 0.999, respectively. Furthermore, schematic empirical statistical models were developed to predict the performance characteristics of several conversion methods using pump data obtained from the manufacturers.


Traylor Industrial is serving as on-site mechanical support for the Shea-Traylor Joint Venture on the Ohio River Tunnel project. Once complete, this project will collect overflows from 25 combined sewer outfalls via a tunnel and storage system located along the Ohio River. The 51 million gallon capacity deep tunnel and integrated deep pump station will capture overflow and send it to the existing sewer system for treatment. Ultimately, this project will protect the Ohio River Valley from overflow during heavy rain and floods.
Traylor Industrial’s work on the project has consisted of various smaller projects to support the construction of the sewer overflow tunnel. They originally started on the project when hired to complete a seven-week job in October 2020, but have since stayed on-site for additional mechanical work with a team of six mechanical craft. This work includes assembly of forms, rail switch units, rebar cars, and shaft door frames.

The 462MW Chaglla hydroelectric power plant, being developed by Odebrecht Energia’s subsidiary Empresa de Generación Huallaga (EGH), will be Peru’s third biggest hydropower project.
Construction of the project began in May 2011 and operations are expected to commence in 2016. The plant is expected to generate 2,500 direct jobs and have an operational life of 30 years. It is estimated it will require an investment of $1.2bn and produce approximately 2.8 Gigawatts/hour a year, while offsetting approximately 467,000t of carbon dioxide emissions from the atmosphere.
Chaglla power plant design and development
The Chaglla hydroelectric project is located on the Huallaga River in the Chaglla district of Huanuco, Peru. It will include a concrete-face rock-filled dam, which will impound a 4.66km² reservoir upstream of the dam, diversion tunnel and hydroelectric generation facilities, comprising a powerhouse, substation and transmission line.
“Construction of the project began in May 2011 and operations are expected to commence in 2016.”
The rock-filled dam will have a maximum height of 202m and a crest length of approximately 273m, while the crest of the dam will be located at an elevation of 1,202m above sea level and 11.2m wide.
The reservoir will have an elevation of 1,196m and water surface area of 4.5km². It will have a storage capacity of approximately 375 million cubic meters (m³), and three tunnels with a total length of 2,850m were proposed on the left margin for spillway discharge.
In addition, the plant will feature two turbine generators with a nominal output of 253MVA and frequency of 60Hz. These turbines will have a nominal voltage of 13.8kV and will operate at a synchronous speed of 900rpm.
Water from the dam will be diverted through a 14.7km intake tunnel to the main powerhouse, which will be equipped with two Alstom power transformers with a nominal output of 225MW. The project will also feature a small power house, including a power transformer with an output of 6MW.
The substation will be situated above the main powerhouse at an elevation between 900m to 925m.
Power transmission from the Chaglla power plant
The power generated by the plant will be transferred to the Peruvian national grid (Sistema Electrico Interconectado Nacional-SEIN) at the Paragsha substation, via a 137km-long, 220kV transmission line.
Construction of the hydropower project
Four sites were created for the construction phase. Major works include the construction of the concrete-face dam with a 466ha reservoir, a surface powerhouse and a 1,053m long diversion, spillway and headrace tunnel. For the foundation and dam construction, an upstream and downstream cofferdam will be constructed at 1,068m and 1,009m respectively.
“The power generated by the plant will be transferred to the Peruvian national grid.”
Construction works also include the river bypass through trunk tunnelling, which has a diameter of 12.5m and length of 1,125m. The upstream cofferdam will measure 66m, while the downstream will be 14m high.
Inter-American Development Bank (IDB) provided a $150m loan facility to Odebrecht Energia for the hydroelectric power plant.
The project was also co-financed by Banco Nacional de Desenvolvimento Econômico e Social (BNDES), COFIDE (Development Finance Corporation), and other international commercial banks, while BNP Paribas acted as the financial advisor.
Alstom was awarded a contract to supply all the hydro and electromechanical equipment, spare parts and services. The scope of supply includes two generation units with total power of 450MW, power transformers and switchyard equipment, as well as the complete mini hydropower plant.
Mott MacDonald was engaged by The Bank of New York Mellon as the independent engineer to monitor the power plant construction. The contractual scope includes providing support for the lenders in the construction, operations and monitoring phases of the project.


Agder Energi has upgraded and expanded the existing Iveland power station on the Otra River. The expansion of Iveland 2 has increased production from 340 GWh to around 500 GWh. This increase is equivalent to the annual consumption of 7,500 households. Sweco has been main consultant to the project since 2009, responsible for interdisciplinary design and follow-up up to completion of the new power station in 2016.
Iveland 2 power station
Iveland municipality, Aust-Agder
Pilot project: 2009–2010
Tender phase: 2012–2013
Construction phase: 2013–2016
Building and structural engineering, electromechanical disciplines, including turbines and power current, (generator), low current, HVAC, fire technology, geology and geotechnics
On 14 June 2016, Iveland 2 was officially opened by petroleum and energy minister Tord Lien. The power station has been built as a new power station inside the mountain. Its maximum operating flow is 100 m³ per second, the nameplate capacity is 44 MW, with a total production of 150 GWh. This contributes to the production of important renewable energy based on unique Norwegian hydropower.
A mini turbine benefits society
To increase the benefit to society of the project, a micro power station has also been built that produces electricity from the remaining flow in the river by utilising the height difference of the dam. A mini turbine will produce energy from water released through the dam at Iveland 2. Utilising the height difference of the dam means that a sufficient volume of water must always flow through the river, out of ecological consideration to flora and fauna, among other reasons.
An interdisciplinary project delivered at the right quality, time and cost
Sweco has been consultant in the pilot project, tender phase and detail phase and has followed the project from start to finish. The plant, which we have designed in 3-D, includes:
We have also assisted Agder Energi as design manager and technical experts on turbines, generators, control systems and geotechnics/geology, as well as follow-up during the construction phase. The Iveland project is a success story in which the plant has been delivered to the correct technical quality, on time and within the cost framework.
Iveland power station is on the Otra River in Iveland municipality in Aust-Agder County, where it exploits the drop between the Gåseflå fjord and Skaiåevja is used.

Reservoir completion delayed due to weather
Spring weather has delayed reservoir construction near Green River.
The raw water reservoir project was initially planned to be a 17-month project, has been under construction for more than a year. The project was originally planned to be completed by late June, but is now expected to reach completion by mid to late summer.
Frequent rain and hail storms passing through the area have delayed the project with shorter work days, but the worst was at the beginning of May. The construction's biggest set back was the heavy rain storm that hit Green River during Mother's Day weekend, Bryan Seppie...


ArmInfo. The Mejlis of Iran at a meeting on April 18 by 162 votes in favor, 5 against and 5 abstentions approved a bill on the construction of a hydroelectric power station on the Araks River. This is reported by the Armenian Embassy in Iran.
"On April 17, the Mejlis at a public meeting decided to start discussions with Armenia on the construction of a hydroelectric power station on the Araks River." It is noteworthy that the program for the construction of the Meghri HPP has been on the agenda of economic cooperation between Armenia and Iran for many years, "the Armenian diplomatic mission said in Iran.
The Meghri hydropower plant was previously considered the most promising joint Armenian-Iranian project. Although the parties have come to the final stage of the project and announced the start of construction in November 2012, the work has not been started yet because of the limitations of Tehran because of the sanctions. If the project is completed, the station will become the largest in the Transcaucasus. Under the project, the construction of a $ 323 million facility will be financed by the Iranian investment company. Armenia will pay for its part of the project with electricity produced at the hydroelectric station itself, and after 15 years the hydroelectric power station will be transferred to the Armenian side.
While the Armenian-Iranian economic relations can not move from the dead point, after the lifting of sanctions, economic ties between Tehran and Baku sharply intensified. The Iranian parliament approved a bill on the joint construction of two hydroelectric power stations with Azerbaijan. The bill allows construction of power plants near the Araks River in the border area, in the Iranian city of Marazad and the Azerbaijani city of Ordubad. The document provides for cooperation in the construction of power stations at the dams of Khoda Afarin and Gyz Galasy, on the Araks River, as well as the construction of the Ordubad Power Station on the Azerbaijani side and the power plant in Marazada on the Iranian side. The ArmInfo agency reported that if the project is implemented, the water volumes for the Meghri hydropower plant in Armenia may simply not be enough. Earlier, adviser to the Minister of Energy Infrastructures and Natural Resources of Armenia Areg Galstyan stated that due to environmental problems related to the reduction of water volumes in the Araks River, as well as the increase of water intakes from Turkey in the northern part of Armenia, it was necessary to revise this project in the direction of power reduction. If initially it was planned to build two stations (Meghri - Armenia, Karachilar - Iran) for 130 MW each and a total power generation of about 850 million kW per year, now the option is considered with a capacity of 100 MW. In this regard, the diameter of the tunnel has been changed, along which water will flow between the two hydroelectric power stations.

The Roendahl Canyon is located in the upstream region of the River Mais east of Mellvere.
In ancient times the River Mais often flooded, causing great damage to cities downstream. Now water levels are controlled using the dams and flood gates built in the canyon. It recently became known that the frequent flooding of the River Mais was largely due to excessive timber logging in the middle ages, reducing the water-holding capacity of the surrounding area. The government is now considering a replanting program.


AHEC Generating Process Animated
It will use the same hydroelectric generating equipment used in China’s Three Gorge Dam. When validated, AHEC’s generating process will store water in two large reservoirs then converts that stored energy into electricity by using the gravity and force of water flowing through hydraulic turbines connected to generators. The water is returned to the reservoir for reuse.
AHEC’s generating process plans to use existing proven hydroelectric generating technology, combined with a solar power rechargeable battery storage system to generate hydroelectricity. To compensate for the Laws Of Thermodynamics, organic solar carbon cells will be including on building windows design that connects to a series of rechargeable Lithium Iron Phosphate Batteries. The batteries would operate 10 Industrial Water Pumps at the bottom of the process and 10 Industrial Vacuum Pumps at the top of the process. Our process uses a closed-loop system that includes two large water reservoirs at the top of the process. The Main Reservoir will be larger than the second Smaller Reservoir, but of equal heights. The water will flow from the Main Reservoir into the Second Smaller Reservoir and then down to the Penstocks to the 40 Francis Turbine Generators. The difference in the water’s height between the main and second reservoir will be used to create a Positive Flow Charge in the Closed Looped System that will help the water return back to the Main Reservoir through the Return Penstock with the aid of Industrial Water Pumps.
Our process was designed to ensure that the Potential Difference between the two reservoirs never reaches zero, in order to maintain a continuous controlled return water flow.
