The Water Display level and increments can also be edited in 3D View Properties
Incrementally decreases the displayed
Incrementally increases the displayed
Pressing the Ctrl+Shift+W key will enable or disable Water Level display in the 3D view window.
When water level is displayed, the number pad '+' key will raise the water level, and the number pad '-' key will lower it.
Rolling the mouse wheel with the Alt key down will raise or lower the water level.
In all cases, the amount used to raise or lower the water level is the water level increment value that appears in the 3D View Properties dialog, but that can be modified: if the Shift key is also held down, the water level increment value used will be multiplied by 4; conversely, if the Ctrl key is also held down, then the water level increment value used will be divided by 4.


Nachtigal hydro power plant is a 420MW run-of-river hydro power project under development on Sanaga River in Nachtigal, Cameroon. The hydropower facility is being developed by Nachtigal Hydro Power Company (NHPC), which is owned by Électricité de France (EDF, 40%), International Finance Corporation (IFC, 30%), and the Republic of Cameroon (30%).
Expected to begin operations in 2023, the €1.2bn ($1.37bn) hydropower plant will generate approximately three terawatt-hour (3TWh) of electricity a year. It is estimated to create more than 1,500 jobs during the construction phase, in addition to saving $100m in electricity generation costs.
The Government of Cameroon (GoC) granted an exclusive right to NHPC, in 2017, to design, build, and operate the project for 35 years under a concession agreement. The rights of the plant will be transferred to the Government, upon expiry of the term.
Nachtigal hydro power lant location
Nachtigal hydro power project is situated on the Sanaga River near Nachtigal falls and is located approximately 65km from Yaounde, the capital city of Cameroon.
The plant will regulate the flow of Sanaga River, alongside the operational Mbakaou, Mapé, Bamendjin, and the Lom Pangar dams.
Nachtigal hydro power plant make-up
The Nachtigal hydropower plant will comprise two roller compacted concrete dams on the Sanaga River, with a length of 2km and a height of approximately 15m. The reservoir will have a surface area of 4.21km² and a storage capacity of 27.8m³.
Water from the dam will be forwarded to the power plant by a 3.3km-long and 14m-deep concrete-lined headrace tunnel, at a rate of 980m³/s.
The powerhouse, which is 142m-long, 36m-tall, and 47m-wide, will be installed with seven 60MW turbines to generate power. An 800m-long tailrace channel will be used to send the water back into the river from the powerhouse.
A 4.5MW secondary power plant is being developed downstream of the dam to generate electricity from environmental flow.
Power generated by the hydropower project will be transmitted to the Nyom 2 substation before being transferred further to the Southern Interconnected Grid (SIG).
A 225kV double busbar substation and a 50.3km-long double-circuit transmission line will be constructed for the same. NHPC is responsible for the transmission line construction, which will be handed over to GoC upon completion.
National Electricity Construction Company (SONATREL) will operate the transmission line.
Financing for the Nachtigal hydro power plant
The Nachtigal hydropower plant is being financed with 75% debt and 25% equity. The total debt funding for the project is $1.02bn, while the funding through equity is $342m.
The project will be the biggest hydropower project ever built in Africa through project finance scheme. The lenders group, including co-developer IFC, comprises 11 finance institutions and four local commercial banks.
Prominent institutions among the lenders group include African Development Bank (AFDB), Agence Francaise de Developpement (AFD), IFC, Societe Generale Cameroun, Standard Chartered Bank Cameroon, Entrepreneurial Development Bank (FMO), and European Investment Bank (EIB).
The consortium of GE Renewable Energy and Elecnor was awarded an $87m contract, in February 2019, for the supply of Francis turbines for the hydropower plant.
BESIX was awarded the contract for the design and construction of the Nachtigal dam, in August 2018. Tractebel and ISL were chosen as the consultants for engineering and civil works of the project.
Bouygues Energies & Services was awarded the contract for the construction of transmission lines for the hydropower plant.
Environmental impact assessment (EIA) for the plant was prepared by Artelia, while Nodalis provided the technical, economic, and financial advisory services.

PESHAWAR (Staff Report) – The government of Khyber Pakhtunkhwa has completed work on 37 mini dams under its power enhancement initiative, according to a statement by Pakistan Tehreek-e-Insaf Chairman Imran Khan.
As per the announcement, 37 mini dams out of a total of 356 planned dams had been built so far to eradicate load shedding and provide uninterrupted power supply in the province.
The completed projects will produce 2 MW, while the total generation capacity of 356 stations is projected to be 35 Mega Watts.
After securing a landslide victory in KP, PTI chief Imran Khan vowed to build 356 micro dams in the province.
The total estimated cost for these projects is Rs. 5.5 billion. Consumers of the power produced through these dams will be charged at Rs.2 per unit through specialized electricity meters.


Long-term stability analysis of Messochora Village
The Mesochora Dam is a 150-m tall concrete-face rock-fill dam on the Acheloos River near Messochora in Trikala, Greece. Although the construction of the Dam was completed in January 2001, the reservoir has yet to be filled due to a variety of legal disputes, one of which is the long-term stability of the hillside village of Messochora.
In this project we acted as a consultants of the dam owner and operator (Public Power Corporation) to assess the stability of the natural slope under rapid drawdown conditions, estimate the earthquake-triggered landslide potential of Messochora Village and conclude on the adequacy of proposed remediation actions.

COMPREHENSIVE EVERGLADES RESTORATION PLAN
Caloosahatchee River (C-43) West Basin Storage Reservoir (C)
Construction General (C)
Congressional Districts: 17, 19, 25
Congress authorized the Caloosahatchee River (C-43) West Basin Storage Reservoir Project in the Water Resources Reform Development Act (WRRDA) of 2014. This project is a component of the Comprehensive Everglades Restoration Plan (CERP). The project is designed to capture excess C-43 Basin runoff and regulatory releases from Lake Okeechobee during the wet season and release water from the reservoir during the dry season. The project includes development of one aboveground reservoir with a total storage capacity of approximately 170,000 acre-feet (ac-ft). The reservoir will be located in the C-43 Basin in Hendry County. The project will reduce the extreme salinity changes in the Caloosahatchee River Estuary by providing a more consistent flow of water discharging into the estuary. The project will also provide water supply benefits and some flood attenuation.

Model TS 150/300/600/900/1500LB - T Type Strainer
This is achieved by tapering the element to make a wide fluid path adjacent to the downstream outlet where reat of flow is large, and make a narrow path for fluid which flows in the opposite direction and exits via the outlet at which flow rate is small. Thus, optimum use is made of the downstream side of the casing. Also pressure losses are smaller and the filtering cycle is larger.

Kathmandu, Jan. 15:
Although works on the project are moving ahead rapidly, a complex situation of having to alter the ‘slope’ of the main headrace tunnel is likely to delay the works. Twelve kilometers of the total 16-kilometre-long tunnel has been completed.
As per the progress report of 21 Projects of National Pride released recently by the National Planning Commission (NPC), the project consultants have recommended altering the gradient at some portion of the underground power house and the transformer cavern ceiling.
The project is faced with the problem of revising the design as the project works cannot proceed ahead without resolving the problem that occurred in the penstock area, the last portion of the main tunnel. Engineers estimate that this will cost Rs. 1.94 billion.
A 29-kilometre approach road has been constructed to the project site. It is said more than 50 per cent of the project works have been completed. So far, more than Rs. 13 billion has been spent on the project.
The estimated cost of the project is 35 billion 700 thousand rupees. Of this cost, the government will bear Rs. 4.7041 billion and Rs. 20 billion would be met through internal loans while Rs. 10.59 billion would be serviced from investment in share.
Revising the design of the project would increase the total estimated cost of the project by approximately two billion rupees.
It is said the project’s annual income would be Rs. 10 billion once it starts producing power. Nepal Electricity Authority has already entered into a power purchase agreement with the project at the rate of Rs 4.6 per unit kilowatt.
The Upper Tamakoshi Hydropower Project is one of the National Pride Projects and is expected to ease the current load-shedding supplying extra power to the national grid.

Pagination or Media Count:
Proposed diversion channels from the Chicago Sanitary and Ship Canal into the adjacent Des Plaines River at Willow Springs Road and Sag Junction, Illinois, were investigated in 160-scale models. Also, a 116-scale section model was used to study performance of the gated structures planned for regulation of flow through the diversion channels. Both diversion channels will have their bottoms in rock with concrete retaining walls above ledge rock. A roadway bridge will cross the entrance of each diversion channel, and flow through the channels will be regulated by control structures comprised of 16-ft-wide vertical-lift gates--10 gates at Willow Springs and 7 gates at Sag Junction. Impact-type stilling basins will be provided to dissipate the flow through the gates. Calibration data, obtained in the models, should be useful in setting up normal and emergency operating schedules. Author

Nigeria with a population of 180 million people has a total installed electricity generation capacity of 8,644 MW. However, the peak generation is much lower at around 4,000 MW. The reasons for the shortfall in generation can be attributed to the inadequate fuel supply to thermal plants which constitute over 80% of the installed capacity, hydro-logical factors for hydro power stations, maintenance outages at power plants and transmission & distribution outages. The Peak demand is forecasted at 12,800 MW. When seen against the available power of less than 4,000 MW, it can be noticed that there is a peak load shortage of more than 8,000 MW. As a result, the available generation capacity is less than one-third of the total peak demand for electricity.

THE Wivenhoe Dam yesterday hit record levels following recent weeks of near-incessant rain in the Ipswich region.
And the most recent dam to be built in the region, the Wyaralong Dam, reached 80 per cent capacity only a month after being ready to hold water.
The dam, which is south of Ipswich between Boonah and Beaudesert, held 83,133 megalitres yesterday, which is 80.7 per cent of its 103,000 megalitre capacity.
A spokesperson for the SEQ Water Grid Manager said the Wivenhoe Dam was currently about 154 per cent full, with the Somerset Dam about 158 per cent.
The drinking water level of Wivenhoe is at 100 per cent, with the remaining 40 per cent level the amount currently held for flood mitigation.
“It is the highest level the dam has been at since construction,” a spokesperson said.
In order to relieve the quickly filling flood storage compartment, controlled releases from the dam increased yesterday from 116,000 megalitres per day to 170,000 megalitres a day.
Although releases are being made, large quantities of water continue to flow into the dams and are being held back in order to manage impacts downstream.
A spokesperson said the releases were a necessity because the Wivenhoe Dam was receiving more than twice the volume of Sydney Harbour each day.
SEQ Water Grid chief executive Barry Dennien said the dam’s mitigation measures were doing their job, and release levels were being carefully monitored.
Parts of the Wyaralong Dam are still under construction, but its wall was plugged to hold water on December 17 last year.
Queensland Water Infrastructure chief executive officer Frankie Carroll said the dam had reached its current capacity after weeks of heavy rain.
“We will continue to monitor dam levels and will release water if and when required in consultation with SEQwater and the Water Grid Manager,” he said.
Mr Carroll said the Wyaralong Dam project was expected to be completed by mid-2011.
Over the next few months, as weather permits, the focus will be on finishing civil mechanical and electrical works and rehabilitating the dam site, as well as completing the extensive network of trails and recreation facilities around the dam.

FIRST stage of a £26m flood defence scheme to improve the safety of a flood storage reservoir dam at Whittlesey has started.
The Environment Agency led project will strengthen the dam of the flood storage reservoir downstream of Peterborough by reshaping it and placing extra material at the base of the bank.
16km of the South Barrier Bank, which forms the reservoir dam between Stanground and Ring’s End near Guyhirn will be improved to reduce the risk of a breach during a flood.
The flood storage reservoir protects hundreds of properties, roads, railways and more than 8000 hectares of farmland in the fenland area to the south east of Peterborough.
Guy Szomi, Environment Agency engineer, said: “We use Whittlesey Washes to store flood water when tides and river flows are high.
“The Washes play an important part in helping to reduce the risk of flooding and our work will further reduce the risk to people and property.
“But while the flood storage reservoir is an effective way of reducing flood risk, no type of defence can remove the risk entirely.”
Whittlesey Washes can be used to temporarily store the equivalent of 14,000 Olympic-sized swimming pools of flood water.
The Whittlesey project will take place over four years and has been split into phases. The first phase is taking place between Ring’s End and Coates. The first phase of flood bank strengthening has begun and will end in autumn 2014.
The car park at Ring’s End will be closed until December.
To minimise disruption and reduce traffic through Whittlesey, Eastrea and Coates, material will be transported to site using the A47, A141 and A605 and a dedicated access track at Goosetree Farm. This means people may notice more lorries than usual along these routes.

Turkey will build a dam on a creek in the Mediterranean region to carry fresh water to Turkish Republic of Northern Cyprus (TRNC) through a 80-kilometers submarine pipeline.
The Alakopru Dam will be constructed on Dragon Creek in Anamur town of the Mediterranean province of Mersin and is planned to be completed within three years once the construction works are started.
The project aims to pump 75 million cubic meters of water yearly to the island, 15 of which will be used as drinking water and the rest for irrigation.
Turkish State Minister Kursad Tuzmen said project design works would be finalized next year.
"This project will be implemented to help TRNC fight drought and carry out irrigated farming," Tuzmen said.
Turkey first started the project in 1998 to build a dam on Dragon Creek and Turkish construction company Alarko was contracted for the project. A memorandum of understanding was signed by Turkish State Hydraulic Works and Alarko in 2005.
The project will bring water to the island from Alakopru Dam through a 80-kilometers submarine pipeline to be installed 120 meters deep in the Mediterranean Sea.
Turkish Cypriot people, cultivating their land by means of dry farming for years, will now be able to carry out irrigated farming, officials said.

The existing 100 year old Lexden Bridge needed to be demolished and a new reinforced concrete single span bridge.
The project involved the careful demolition of the existing bridge before the construction of new in-situ reinforced concrete abutments and a steel beam & reinforced concrete bridge deck, supported on new 15m deep concrete piles.
The resultant raised height of the new bridge deck required a change to the vertical alignment of the carriageway approaches on either side.
A temporary footbridge and footpath was constructed to maintain pedestrian access across the River Colne and an Aquadam and floating pontoon system was employed to enable the watercourse to remain flowing whilst the existing abutments and wing walls were demolished and the new abutments constructed.
It was necessary to overcome a further challenge of constant flooding of the site throughout the duration of the works due to its location within a floodplain.
Hague Construction met this additional challenge by means of localised sheet piling and temporary works to protect and mitigate the effect of the flood water on the works and the construction program.

Site C Clean Energy Project is a dam and hydroelectric generating station being developed in British Columbia, Canada.
The project will have a total capacity of 1,100MW and a potential annual generating capacity of 5,100GWh of clean and renewable electricity. It received environmental approval from federal and provincial governments in October 2014.
British Columbia Hydro and Power Authority (BC Hydro) will own and operate the project.
Site C location details
Site C will be the third dam on the Peace River, which originates from the Rocky Mountains located in the north-eastern parts of British Columbia. The other two existing dams are W A C Bennett and the Peace Canyon dam, both of which are located upstream of the proposed Site C dam.
Site C is expected to require an investment of C$7.9bn ($7.907bn). Site preparation activities began in August 2015, and the dam is scheduled to start generating electricity by 2024.
The reservoir created by the dam will cover a surface area of 9,330ha, including the controversial flooding of approximately 5,550ha of land.
Approximately 35,000 jobs are expected to be created during the development and construction period, along with a further 10,000 direct construction positions.
Site C development and history
The project is being undertaken to fulfil British Columbia’s growing electricity needs, which are expected to grow by approximately 20% to 40% in the next 20 years. If successful, it will be capable of serving 450,000 homes annually for 100 years.
The possibility of constructing the proposed dam was first identified in the 1950s, although the preliminary design phase was first conducted in the 1970s.
An original layout of the design was completed in 1981 and further engineering activities were carried out between 1989 and 1991. BC Hydro then decided to upgrade the design to meet the current seismic, safety and environmental guidelines. This revised design was completed in 2010.
The announcement to proceed with project activities was made in April 2010, while the regulatory review phase of the project, including consultations with various bodies, was carried out between 2010 and early 2013.
In addition, the environmental impact statement (EIS) for the project was submitted to the Canadian Environmental Assessment Agency and the British Columbia Environmental Assessment Office in January 2013.
Site C Clean Energy Project and reservoir details
The proposed project will include an earth-fill dam measuring 1,050m in length and 60m in height.
Site C’s reservoir will stretch for 83km, and the dam will consist of a main spillway, auxiliary overflow spillway and inlet/outlet diversion tunnels. The main spillway will include seven gates, and two cofferdams will be built as part of the dam construction.
The generating station will comprise power intakes, penstocks and six units, each with a capacity of 183MW.
The proposed dam will primarily use storage water from the existing Williston reservoir and re-use water from the existing dams upstream. This will enable the dam to generate approximately 35% of the energy produced at the W A C Bennett dam using just 5% of its reservoir area.
Dam construction and infrastructure
Concrete buttresses will be used to strengthen various structures, including the foundation of the power station, spillway and wall of the valley in the south. This will provide seismic protection and structural stability.
Access roads and a temporary access bridge for transportation during the construction phase will also be constructed.
The project will also involve the realignment of six segments of Highway 29, covering a distance of roughly 30km.
Grid connection for the Canadian hydroelectric power project
Power generated by the new hydroelectric station will be transported to the existing Peace Canyon substation through two AC transmission lines with a rated capacity of 500kV, travelling a distance of approximately 77km.
Contractors involved with the Site C Clean Energy Project
Two Rivers Lodging Group was awarded a $470m, eight-year contract for the design, construction, partial financing, operation and maintenance of worker accommodation at the Site C dam site.
Paul Paquette and Son’s Contracting secured a contract for clearing the south bank of the Site C dam construction area. The scope of the contract includes the removal of 620ha of trees and vegetation, construction of temporary access roads, upgrade and maintenance of existing access roads and collection as well as removal of waste wood.
Morgan Construction and Environmental received a contract for site preparation activities, including the construction of access roads and site clearance works on the north bank.
Peace River Hydro Partners was awarded a $1.75bn contract for the construction of the earth-fill dam, two diversion tunnels and a roller-compacted concrete foundation for the generating station and spillways.
The Sir Adam Beck (SAB) hydroelectric power generating complex is located at Queenston Heights, Ontario, Canada.

The Mepco Model R Series Pumps meet the latest standards for hydraulic performance and dimensional characteristics.
The pump shall be close coupled to a NEMA standard JM Motor.
The pump incorporates a dry shaft design to prevent the fluid from contacting the shaft.
The shaft is covered with a replaceable bronze stainless steel shaft sleeve.
The standardization and interchangeability for the R Series pump line results in reduced parts inventories and lower costs for multiple pump installations. An easy to replace slip on shaft sleeve facilitates seal maintenance in the field and lowers costs. The dry shaft design protects the pump shaft by eliminated contact between the shaft and the fluid. Corrosion resistant shaft materials are not required. Standard brass sleeve or optional stainless steel will eliminate this maintenance problem.
The Mepco model R pumps are ideally suited for a variety of applications, including heating, air conditioning and pressure boosting.
The pump is capable of being serviced without disturbing the system piping with pump back pull out design. The advanced impeller design maximizes hydraulic efficiency, dynamically balanced for vibration free operation. The mechanical seal is constructed of Buna N and is rated for 225 ° F. and pressures up to 175 PSI with ceramic seat and carbon seal face for long trouble free service. Alternative seals are available to suit other temperatures and liquids. The R model's dry shaft design ensures shaft is never exposed to the system fluid. This feature simplifies sleeve and seal removal/reassembly.

Construction starts this week on works to reduce flood risk to properties in the upper and mid Heathcote area.
Since the earthquakes, flooding has increased along the Heathcote River. The Council's Land Drainage Recovery Programme has been investigating the benefits of increasing flood detention storage in the upper Heathcote, around Hendersons Basin. The team has looked at whether this would help homes along the Heathcote River which have an increased risk of above floor flooding as a result of the earthquakes.
Initial modelling results have shown increased floodwater storage in the Hendersons Basin area would have a positive impact in reducing this flood risk downstream. Other mitigation solutions will still be required to reduce this risk to pre-earthquake levels.
The work starting today on two flood detention basins to double the storage capacity at an existing stormwater management area known as Eastman Wetlands, marks the first small step of further works to reduce water levels downstream in the mid and upper Heathcote catchment.
Additional storage in Hendersons Basin will not reduce flood risk in the lower Heathcote, due to the tidal influence in the lower reaches.
To facilitate future projects to increase storage, the Council purchased two properties in Hendersons Basin, totalling nearly 37 hectares, at the end of 2015. Work is currently underway to maximise the storage potential offered by this land, and maximise other storage opportunities within the area.
Work the Land Drainage Recovery Programme is doing across the city to reduce flood risk to pre-earthquake levels.

Estimation of the URBS model parameters for flood estimation of ungauged catchments in the upper Ping river basin, Thailand
Punpim Puttaraksa Mapiam, Nutchanart Sriwongsitanon*
ABSTRACT: Flood hydrographs are usually estimated from models on gauged catchments. Flood estimation on ungauged catchments requires relationships between model parameters and catchment characteristics. In this study, both the URBS model and Nedbor-Afstromings model (NAM) were shown to be successful in simulating flood behaviour in the upper Ping river basin, Northern Thailand. To formulate the relationships for applying to ungauged catchments, we chose the URBS model as it requires only 4 parameters whereas the NAM requires 6. The relationships between the URBS model parameters calibrated from 11 runoff stations and the corresponding catchment characteristics were adopted to estimate the URBS model parameters at 4 runoff stations in the target area as if the catchments were ungauged. The results of flood estimation obtained from the ungauged catchment approach were then compared with that gained from the gauged catchment approach. The results revealed that the proposed relationships between the URBS model parameters and catchment characteristics can be confidently applied for flood estimation of the ungauged catchments within the catchment area of the 11 stations used in the formulation process.
