Three Gorges Dam - China
The Three Gorges Dam on the Yangstze River, the largest water conservancy project ever under taken is now being built at Sandouping in the middle of Xiling Gorge, the longest one among the famous Three Gorges. The Three Gorges Dam will be 2,335m long, 185m high, 18m wide on top and 130m wide at the bottom. The Dam will raise the river to a level of 175m above sea level, creating a 370 mile (600km) long reservoir with a storage capacity of 39.9 billion cubic meters extending from the dam-site all the way to Chongqing. 570,000 acres of farmland and 1000 towns and villages in 19 counties and cities will be flooded, causing 1.3 million people to be relocated. The construction of the project will cost 230 billion Chinese Yuan, an equivalent of 28 billion US dollars. The purposes for building this huge dam are flood control, electricity, navigation and irrigation. The construction of the dam formally began under way in 1994.The first stage of the Three Gorges Dam project is scheduled for completion in 2003. Although the scenery will change along the Yangtze with the construction of Three Gorges Dam, new sites and scenery will be created. For example, a submarine museum will be built to preserve the inscriptions on the White Crane Ridge, and many historical sites will be moved to higher ground. After the dam is completed in 2009, ships will continue cruising the Yangtze River; passengers will then be passing through the largest national park in the world, which will be established upon completion of the dam. There are more than 30 cruises calling at this port. Click the month or cruise line logo you are interested in to see details of the cruises.


The dynamic tidal power requires the construction of the sea dam long enough to tidal influence and reverse flows was effective. The energy of such power stations is produced when water moves through the turbine in either direction. The dam, built in the way of olives or tidal waves, creates a level difference, which is used to rotate turbines.
To power able to work effectively, according to Gijs bath of banning (Gijs van Banning), a leading specialist ARCADIS Nederland BV, it is enough to create the difference in water levels between different sides of the dam, at least 20 – 30 cm.
Unlike traditional projects, such as the Rance tidal power plant in France, which flooded the territory at the mouth of the river, dynamic station does not require the creation of isolated pools, which reduces the load on the environment and will not result in social impacts.
Preliminary studies have shown that the dynamic tidal power plants along the Chinese coast can be with the capacity of 15 GW and even more, which makes the joint energy project one of the largest in the world.
Theoretically, the power of large-scale dynamic tidal power plant dam with a length of 70-100 km can reach 22 GW. According to van banning, the effectiveness of the system depends on the length of the dam.

Maldives Transport and Contracting Company (MTCC) has commenced physical works of the harbor reconstruction project in GDh. Kaadedhdhoo. MTCC said it began physical works of the project last Monday. MTCC commences harbor reconstruction project in GDh. Kaadedhdhoo. (Photo/MTCC) Under the project, MTCC will construct a 170-meter quay wall and an 890-square meter harbor pavement. The project is valued at MVR 9.52 million.


In order to solve the problem of oil trapping in gear pump, we usually open symmetrical unloading groove in the ductile iron pump cover, or open asymmetric unloading groove in the direction of the low pressure side, and suction side uses conical unloading groove, discharge side for the rectangular unloading groove. The depth of the unloading groove is deeper than the hydraulic industry used in the gear pump.
The ductile iron pump cover is placed on the upper end of the reservoir of the brake pump or clutch pump. Ductile iron pump cover with rubber seal is to prevent brake fluid leakage and water into it. Ductile iron pump covers may be made of plastic or metal. The shape is round, square or rectangular and is located by thread, bolt or wire hoop.
The pump body is composed of suction chamber and pressure chamber. The inlet of the suction chamber and the outlet of the pressurized water chamber are respectively the inlet flange and the outlet flange of the water pump for connecting the inlet pipe and the outlet pipe. The inlet flange and the outlet flange are often provided with small holes for the installation of vacuum gauge and pressure gauge respectively. The suction chamber is generally a section of tapered short pipe or straight pipe gradually shrinking, whose role is to introduce water into the impeller, and provide the impeller with the required flow pattern. There is a baffle in the cone to prevent the water from pre-rotating before it enters the impeller. The function of the chamber is to collect the liquid from the impeller and direct it to the outlet. The shape of the pressurized water chamber is like a snail shell, commonly known as the volute, the impeller is enclosed in the volute.
The top of the pump body is provided with a vent hole (irrigation hole) for vacuuming or water filling. A water hole is arranged at the bottom of the shell, which is usually plugged with square head bolts. It is used to drain water in the empty pump body after shutdown to prevent the parts inside the pump from corroding and freezing in winter. The pump body is made of cast iron or cast steel and its inner surface needs to be smooth to reduce hydraulic loss.
Ductile iron pump cover is connected with the pump body by bolts, in which there is a bore hole to form a packing box, which is filled with plug packing, or mechanical seal and other forms of high pressure plunger pump to prevent air or water from entering or flowing out of the gap between the shaft and ductile iron pump cover.

Water / Wastewater PROJECTS | Trinity River Authority Denton Creek Regional Wastewater System Peak Flow Storage and Rehabilitation
Denton Creek, TX
Ardurra is supporting a wet weather flow storage initiative for the Trinity River Authority’s Denton Creek Regional Wastewater System. Key features of our project include:
The project includes the evaluation and design of new wet weather flow storage facilities to temporarily store peak wet weather flows and reduce the impact of increased flows on the treatment plant. The team analyzed historical rainfall data in conjunction with a collection system hydraulic model to determine impacts to flows resulting from extended wet weather periods. This unique analysis yielded a roadmap for developing a methodology that allowed the owner to select an appropriate storage volume in correlation to the acceptable percentage of USGS storm covered (from 0- up to 100-year storm criteria).
This approach allowed designers to take full advantage of the collection system characteristics to optimize storage volume versus storm coverage. As part of the process, a Pollutograph, representative of a typical “first flush” event was developed. The recommended storage alternative includes odor control, a flushing system for storage tanks, and a return flow pumping system. The project will accommodate wet weather events and provide additional operational flexibility for construction sequencing and other process needs for 65 percent of storm events.

A novel decentralised Sustainable Refugee Camp Drainage System (SRCDS) has been developed for the effective management of stormwater in the Dadaab refugee camp, Kenya. The SRCDS uses the principle of Best Management Practices (BMPs) for runoff generated from extreme rainfall events in order to minimise flooding of inhabited areas of the camp. The performance of the drainage system was modelled by the Storm-water Management Model (SWMM) and Micro Drainage Sustainable Drainage Systems (MDSuDS) software to obtain: (i) the total stormwater flow in a sub-catchment in order to obtain total runoff volume and peak runoff rate and (ii) the required dimensions of the SRCDS to effectively drain and store runoff for reuse. The results showed that the total volume of runoff generated over the sub-catchment area reduces significantly as the volume of water drained by the SRCDS increases, and the peak runoff rate decreases as the size of the SRCDS increases. The SRCDS was effective in dealing with the peak rate and total volume of runoff anticipated.

Friends of the Napa River urge the authorities to fight for the completion of the Napa Flood Control Project. FONR supported the study and reviewed the findings. The project needs to be completed to protect Napa neighbors from flooding as promised when voting for Measure A.
Armed with data from a $415,000 engineering study, the local flood district will be trying to shake loose additional money from the U.S. Army Corps of Engineers to keep the flood project from shutting down.
Currently, the Corps intends to end the flood project next year when construction of the $12.5 million bypass channel bordering downtown Napa is finished.
If that happens, a large swath of the neighborhood near the river would still get wet in a major flood, contrary to the project goals that county voters approved in 1998 when they passed Measure A, a half-cent flood control sales tax.


Some A Bout Hydro Turbine Generator
Author: source: date: 2019-01-24 09:23:28
Hydro turbine generator is used for power generation, Its principle is Water energy converted into mechanical energy to generate electricity. Most of the modern turbines are installed in hydropower stations to drive generators to generate electricity. In the hydropower station, the water in the upstream reservoir is led to the turbine through the water conduit, pushing the turbine runner to rotate and driving the generator to generate electricity. The finished water is drained downstream through the tailpipe. The higher the head and the greater the flow, the greater the output power of the turbine. Turbine and auxiliary machinery are important hydropower equipment, which are an indispensable part of the hydropower industry. They are important equipment for making full use of clean renewable energy to achieve energy conservation and emission reduction and reduce environmental pollution. The comprehensive strength of China's turbine and auxiliary machinery manufacturing industry has increased significantly. The whole industry has shown a prosperous situation of vigorous development and vitality. The industry's better sign is reflected in the improvement of economic operation quality and the significant increase in economic benefits.
Hydro turbine generator have many types, different types suit different situation (such as different water head, flow rate, voltage , frequency and so on) . there are five types hydro turbine generator in our company:
1 Kaplan turbine generator
2 Francis turbine generator
3 Pelton turbine generator
4 Tubular turbine generator
5 Turgo turbine generator
Firstly the Kaplan turbine generator suit low water head, large flow rate, the water head is about 9-15m, and if will install Kaplan turbine, then the project need build Vortex stone. Under the same head, its specific number of revolutions is higher than that of a Francis turbine. When customer tell us they need Kaplan turbine, we should ask them whether they have built up the vortex stone on this project.
Secondly Francis turbine generator is the most widely used turbine in the world, can use of suitable water head and suitable flow rate, the water head is about 15-200m, the blade is switchable. This kind of turbine have more applicable. Compared with the axial flow paddle type, the structure is simpler, the operation is stable, and the highest efficiency is higher than that of the axial flow type.
Thirdly Pelton turbine generator suit high water head, low flow rate, the water head is about 150-700m.
Fourth Turgo turbine generator suit medium and high water head, the flow rate is smaller than Francis turbine generator, the water head is about 70-250m. The inclined flow turbine has a complicated structure and high cost. Generally speaking, the Pelton turbine generator and Turgo turbine generator can exchange with each other, the Pelton turbine generator have better performance, they all can produce with several nozzles.
Fifth is Tubular turbine generator, this generator high efficiency, large overcurrent capability, high specific speed, and it’s suit low water head and larger flow rate, and it is self-contained volute, and it have bent pipe, so it have high installation requirements.
Hydro power generator unit including: water turbine, generator, inlet valve, governor, computer control panel, and other ancillary equipment. In the present power system, the hydro-turbine governor has become the central part of a hydro-turbine control system.

The pump is a machine for moving fluid. The pump moves fluid from a low pressure place to a place with a higher pressure, to overcome this pressure difference a power is needed. The cooling system is a system that serves to keep the engine temperature in ideal conditions.Seawater cooling pump used on the MV.BAHARI 22 ship, experienced a problem of decreased suction power analyzed using quantitative research methods in which research uses data taken directly on the ship. Then the analysis of this study uses a predetermined formula. Research findings and analyzed data are head loss which includes static head, head pressure, head speed, head major loss, head minor loss.
The decrease in the pressure of the sea water coolant pump on the ship is caused by the total head of the system which exceeds the pump head where the head of the system according to the calculation is 61 m, while the maximum head of the pump is only 55 m so that the cavitation in the pump is ensured which causes impeller damage and damages the house the snail This can be proven from the calculation results where the NPSHr value = 5.49 meters far exceeds the NPSHa value which is only 2.52 m.

THE National Irrigation Administration (NIA) said it launched the construction of the P893-million Balbalungao Earthfill Dam in Lupao, Nueva Ecija.
NIA Administrator Ricardo R. Visaya led the groundbreaking and capsule laying ceremony for the earthfill dam earlier this month. The project is known as the Balbalungao Small Reservoir Irrigation Project.
The irrigation project serves 840 hectares and 562 farmers and their families in the Lupao barangays of Balbalungao, San Isidro, Salvacion, Sto. Niño, and Mapampang.
Mr. Visaya said the reservoir will affect 38.44 hectares of land and will not disturb residential areas.
Mr. Visaya said that once the construction of the dam is finished, it will also supply power.
“There will be a hydropower component to be installed before the irrigation outlet of the dam,” Mr. Visaya said. — Revin Mikhael D. Ochave

BROOMFIELD – MWH Global in Broomfield landed a $4.4 million contract to design a new spillway at the Panama Canal.
MWH was hired by the Panama Canal Authority to provide preliminary and final design services for a new spillway at Gatun Lake.
The spillway controls water levels of the lake, which in addition to providing water supply for Panama City and flood protection, is instrumental in the operation of the navigation locks of the Panama Canal.
MWH will design a new spillway to increase the outflow capacity of the existing spillway system, which the Canal wants to increase to manage the maximum expected flood. The nearly century-old spillway system is part of the Gatun Dam, which crosses the Chagres River to impound Gatun Lake.
“MWH is pleased bring our world-class expertise in spillway engineering and design to this project,” says Rex Bell, who leads MWH operations in Latin America. “Maximizing the effectiveness of the spillway is essential to assure the integrity and viability of the Panama Canal system, not only for the existing locks but for the new Third Set of Locks project of the Panama Canal expansion.”

Minor flooding along Mississippi River in Missouri
ST. LOUIS (AP) — The Mississippi River is above flood stage at several northeast Missouri locations, but forecasters do not expect major flooding.
The National Weather Service map of river observations shows that the Mississippi is generally 2-4 feet above technical flood stage from the Iowa border south to near St. Louis. A few fields and low-lying roads are affected, but no major damage has been reported.
The forecast calls for the river to drop below flood stage in a week or so, depending on the location.
Minor spring flooding is common due to rain and runoff from the north.

Idukki Dam (File Photo) | Photo: Mathrubhumi
Idukki: Blue Alert has been issued in Idukki following the rise in the dam’s water level. The action was taken as the water level inched closer towards the storage capacity of the Idukki dam. The current water level is at 2390.86 feet. The maximum storage capacity is 2403 feet. The KSEB officials have informed that there is no need for concern amidst the prevailing blue alert.
The orange alert will be declared only once the water level touches 2396 feet. The red alert is declared when the water level reaches 2397 feet. The shutters of the island are opened only when the water level of the dam reaches 2403 feet. The instruction issued by the Central Water Commission states that the blue alert must be declared at least 36 hours prior to this. The recent declaration of blue alert is a precautionary action taken as part of this.
Presently, there is no rain in the areas surrounding the dam. The flow of water is also low. Thus, it is hinted that the water level in the dam will not rise further. The Meteorological Center has informed that heavy rain is expected in Kerala for the next two days. Orange alert has been declared in Palakkad and Malappuram today. Yellow alert has been declared in all districts other than Kozhikode and Wayanad.

In an effort to reduce the number of structures at risk for flood damage in the event of a 100-year flood, the Harris County Flood Control District (HCFCD) and the U.S. Army Corps of Engineers are in a cooperative effort to widen 21 miles of Brays Bayou across Houston, TX. Project Brays includes 13 separate channel modification projects, 32 bridge modification projects, and the construction of four stormwater detention basins with a combined capacity of 3.5 billion gallons.
The Ardmore Street Bridge, in south central Harris County, is one such structure that is being replaced with a new higher, longer, and wider bridge that will increase the flow of stormwater beneath it and significantly reduce the chance of flooding in surrounding neighborhoods. The new bridge will also improve traffic with the inclusion of a new turn lane and expanded sidewalks.

Tarbela Dam is one of the world largest filled dams with a capacity of 13.69 km³. It is the backbone of Pakistan, and it is used for both power generation and irrigation. Like all dam reservoirs, sedimentation decreases the life of the Tarbela dam reservoir and affects the power generating unit and tunnel equipment’s and instruments. The Finite Volume Method was used to conduct a CFD analysis to investigate different parameters that influence sedimentation. The analysis was carried out using multiphase flow (air and water) considering the summer season for maximum reservoir inflow and discharge water through spillways and tunnels. Boundary conditions were applied to a 3D geometric model that had been meshed. The spillway outlet was found to have the highest velocity. Near the spillways outlet and tunnel inlets, strong vortex motion was observed. WAPDA were suggested to redesign tunnels 3 and 4 in order to reduce sediment inflow, as well as to improve the design of the spillways.

Estimates of extreme water level return periods in river systems are crucial for hydraulic engineering design and planning. Recorded historical water level data of Taiwan’s rivers are not long enough for traditional frequency analyses when predicting extreme water levels for different return periods. In this study, the integration of a one-dimensional flash flood routing hydrodynamic model with the Monte Carlo simulation was developed to predict extreme water levels in the Danshuei River system of northern Taiwan. The numerical model was calibrated and verified with observed water levels using four typhoon events. The results indicated a reasonable agreement between the model simulation and observation data. Seven parameters, including the astronomical tide and surge height at the mouth of the Danshuei River and the river discharge at five gauge stations, were adopted to calculate the joint probability and generate stochastic scenarios via the Monte Carlo simulation. The validated hydrodynamic model driven by the stochastic scenarios was then used to simulate extreme water levels for further frequency analysis. The design water level was estimated using different probability distributions in the frequency analysis at five stations. The design high-water levels for a 200-year return period at Guandu Bridge, Taipei Bridge, Hsin-Hai Bridge, Da-Zhi Bridge, and Chung-Cheng Bridge were 2.90 m, 5.13 m, 6.38 m, 6.05 m, and 9.94 m, respectively. The estimated design water levels plus the freeboard are proposed and recommended for further engineering design and planning.

A three-dimensional, unstructured grid, hydrodynamic and suspended-sediment transport model (i.e., SELFE-SED) was developed to simulate temporal and spatial variations of suspended sediment and was applied to the subtropical subalpine Tsuei-Feng Lake (TFL) of Taiwan. The model was validated with measured water level and suspended‑sediment concentration in 2009, 2010, and 2011. The overall model simulation results are in quantitative agreement with the observational data. The validated model was then applied to explore the most important parameter that affects the suspended-sediment concentration and to investigate the effect of wind stress on the mean current and suspended‑sediment distribution in this shallow lake. Modeling results of sensitivity analysis reveal that the settling velocity is a crucial parameter and erosion rate is less important in the suspended-sediment transport model. Remarkable lake circulation was found based on the strength of wind speed and wind direction. Strong wind would result in higher mean current in the top layer and suspended-sediment distribution in the top and bottom layers. This study demonstrated that the wind stress played a significant influence on mean circulation and suspended-sediment transport in a shallow lake.

Municipal power plant Inn, Prutz/Ried
Civil Engineering Underground engineering
A consortium with Jäger Bau built the power house for the Inn municipal power plant.
The power plant was built on the upper River Inn, in the Swiss-Austrian border area. This building was the largest hydroelectric power plant to be built in the Alps for many years, and will generate over 400 gigawatt hours of electricity from hydropower annually after its completion in 2018.
The power house is the heart of the power plant and was built almost entirely underground; only 4.5 m of the building protrude above the ground. The bulk of the equipment - such as turbines and generators - was installed in the approximately 26-m-deep shaft of the power house.
The excavation of the main construction pit was carried out entirely underwater and required the removal of several hundred thousand cubic metres of rock. The power house was executed in solid construction, and about 25,000 m³ of concrete used.
The contract includes the following services:
Construction of the entire road system (approx. 1.5 km of mountain roads)
Construction of the deep excavation pit (depth of up to 15 m, over 10 m of which is in the groundwater flow of the Inn) using diaphragm walls and prestressing anchors
Construction of deep sealing bases (gel soles) and anchored underwater concrete bases (using divers)
Construction of the entire groundwater drainage system for the power house, open drainage combined with a dewatering well
Construction of the underwater channel as a twin-cell cross section from the power house through to the Inn (length 300 m, section 22 x 4.5 m) including groundwater drainage
Implementation of the environmental measures prescribed in the EIA procedure


The project, which will have a nominal capacity of 325MW, is proposed by ATCO Australia with the support of Altura Group.
The scoping report for the project was submitted end of April 2022, followed by the issuance of Secretary's Environmental Assessment Requirements (SEARs) in June 2022.
As of July 2023, ATCO is finalising CWPH’s Environmental Impact Statement (EIS).
Subject to approvals, construction works are expected to start in late 2024 with commencement of operations slated in 2029.
Once complete, the Central West Pumped Hydro Project will store 2,600MWh of energy (eight hours). This is enough to power 153,000 homes.
The project will store energy during surplus electricity generation; and generate and deliver during emergencies and peak demand periods.
CWPH Location and Site Access
The Central West Pumped Hydro Project will be developed on private land, around 21km southeast of Bathurst and 180km west of Sydney.
The site lies at the end of Molybdonite Road, which connects to the National Highway route A32, the Great Western Highway.
Approximately 85 hectares (ha) will be covered by the permanent infrastructure of the project and 170ha by the development footprint.
Additionally, around 460ha has been selected surrounding these areas as project study area (project site boundary).
Central West Pumped Hydro Project Details
Key CWPH infrastructure will include an embankment dam forming an upper reservoir; a rock-filled embankment dam forming a lower reservoir; a pipeline (penstock) connecting the upper and lower reservoir; sub-surface powerhouse with two pump-turbine units; and transmission connection infrastructure.
The upper reservoir, with a crest height of approximately 2m above the maximum operating level, will have a surface area of approximately 30ha and 15m operating range. It will be designed to store 3 gigalitres of water needed for the operation of the project.
This reservoir will connect to the water conveyance system (penstock) through a concrete intake structure. The water conveyance system will consist of a surface penstock (steel pipeline) of approximately 1,400m length and 5m diameter. The system will have a 150m section of headrace tunnel lying directly under the escarpment at the upper reservoir.
The penstock will bifurcate into individual unit penstocks which will be connected to the powerhouse.
There will be a mass concrete structure, powerhouse, approximately 60m below the natural ground level.
The powerhouse will house two reversible Francis pump-turbine units and other associated equipment for power plant operation.
The project’s lower reservoir will lie within Frying Pan Creek and will have a rock fill embankment dam, This reservoir will cover an area of approximately 30ha and will have about 19m operating range.
A secondary dam, of approximately 1,000m upstream of the main dam, will be considered for development in detailed engineering phase with dimensions of 15m height with base width of 50-100m.
The bottom outlet of the main dam will receive water and then, will enter the secondary dam, if constructed. From here, water will pass slowly downstream into the Frying Pan Creek and then into the Fish River through energy dissipation structures.
A permanent water supply pipeline, of 350mm-500mm diameter, is proposed to be built underground with above ground sections according to the conditions. It will likely be made of High-Density Polyethylene (HDPE).
This pipe will allocate water from the Fish River to the upper or lower reservoirs and for this, a pump is proposed to be installed adjacent to the point of extraction. It will receive power from co-located electrical cable with buried water supply pipeline.
To access lower and upper reservoir sites, a private access road of approximately 8km in length will be constructed which will enter private land through the Council Road.
The Central West Pumped Hydro Project will be connected to the TransGrid transmission network of 330kV, located approximately 6.8km north of the project site.
It will be connected to the 330kV underground transmission line via a 6.8km- long cable. The connection infrastructure will a switchyard located adjacent to the powerhouse.
WSP Global, an engineering and professional services company, was selected for delivery of the reference design of major project elements and assistance in refining its scope, schedule, and budget.
The geotechnical site investigations and reporting were also conducted by WSP.

Abstract: Since 1993, Devils Lake water level has risen by nearly 10 meters and caused extensive flooding in the surrounding area, and greatly increased the chance of natural spillage to the Sheyenne River. To mitigate Devils Lake flooding and to prevent its natural spillage, two outlets were constructed at the west and east sides of the lake to drain the lake water to the Sheyenne River in a controlled fashion. In this study, we propose to investigate the impact of this increased water inflow from the outlets on the Sheyenne River streamflow and floodplain by coupling SWAT and HEC-RAS models. SWAT is a hydrological model which will be used to simulate the Sheyenne River streamflow in presence and absence of the outlets. HEC-RAS model applies to calculate the impact of outlets on the Sheyenne River floodplain using SWAT-simulated streamflow as input. Finally, the results of the coupled model will be integrated with our previous findings for Devils Lake to control the lake flooding while preserving damage to the downstream river.


A large amount of water has been released from the reservoir created by the Khakovka Dam in southern Ukraine, which was partially destroyed on Tuesday. This water was specifically used to cool the nuclear power plant in Zaporizhia.
The Zaporizhia nuclear power plant in southern Ukraine, in Russian-occupied territory, continues to pump water from the Khakovka Dam reservoir to cool fuel, the International Energy Agency said Thursday evening.
After the inspection, the UN body explained in a press release that “even if the level falls below the threshold of 12.7 meters, pumping operations can continue.”

However, a little earlier, the operator of the dam announced that the reservoir volume of the partially destroyed Khakovka dam in the south of Ukraine was insufficient to ensure cooling of the plant’s furnaces. Nuclear power plant.
The boss of Ukrainian operator Ukrhydroenergo Igor Syrota explained that the water level, which is “below the critical threshold of 12.7 meters”, is insufficient to supply “the basins of the Zaporizhia nuclear power plant” for cooling operations.
