Wave and Structure Modeling
A wave model is needed for multiple porous layers such as submerged breakwaters and sandy beaches. Until now, the Boussinesq equations have been developed for water with upper nonporous and lower porous layer. These models cannot be applied for rubble mound breakwaters or sand beaches. In this study, we develop a Boussinesq model for waves in two porous layers which can solve the aforementioned problems. The developed model considers drag and inertial resistances. The validity of the developed model is examined by comparing numerical results with analytical solutions and hydraulic experimental data.

One of the striking features of the Tehri Dam is that it is one among the very few embankment dams in the country. The construction material for the dam has been devised by making use of various types of rocks and earth fillings. This has been done so keeping in view the possible erosion that the surrounding atmosphere can cause to the dam. By making use of the rock and sand embankment, the dam has been rendered waterproof to prevent erosion.
The Tehri Dam is one among the biggest dams in the country and even the world. It is eight hundred and fifty feet high and five hundred seventy five meters long. It has been constructed for a mega power project under the Tehri Hydro Development Corporation. When operational, the dam is likely to generate 2000 MW of power.
The Tehri Dam is built across the river Bhagirathi, a tributary of the Ganga, was brought into the project stage in 1961. It was initially conceived to generate 600 MW of hydroelectric power. The actual construction of the dam began in the year 1978. There were several delays in the construction of the dam owing to protests from the local population over their displacement. Further, the acute shortage of funds for the project caused more delays. Even though, the project received financial aid from the USSR, the fund flow ended owing to the political turmoil that erupted in that nation. Thereafter, the Indian Government formed the Tehri Hydel Development Corporation Ltd., which was a joint undertaking between the Central Government and the state of Uttar Pradesh.
There were several changes made in the design of the project and thus this became a mega project capable of generating 2000 MW power. As per the design of the project, the power generation that makes use of pumped storage water is to be commissioned in early 2016.
Within the Tehri Dam lies the Koteshwar Dam that is capable of generating 400 MW of hydroelectric power. Along with the generation of power, the fully functional Tehri Dam will be capable of providing irrigational water to six lakh seventy thousand acres of land. The project is also slated drinking water on a daily basis to several areas of Delhi and several cities of Uttarakhand and Uttar Pradesh.
As quoted above, the prime delay in the execution of the project was owing to the protest against the construction of the Tehri Dam. The protest was staged at the national as well as the international levels. The very construction of the dam at the foothills of the Himalayas was questioned and debated upon by several leading environmental groups. They carried the firm opinion that an earthquake of higher magnitude would wreck havoc over a vast area owing to the collapse of the dam and the deluge of the water that would ensue.
The displacement of the inhabitants of several villages amounting to nearly one lakh people and the destruction of the sanctity of the Bhagirathi River are further reasons for the protest against the dam.
At present, the project is generating up to three thousand million units of power every day.

Flood Warning For Laramie River Updated
The National Weather Service is continuing a Flood Warning for the Laramie River at Laramie.
Residents are advised that the river is expected to rise near flood stage, which is 8 feet, late on Friday, June 5 or early Saturday.
The river is projected to fall back below flood stage around noon on Monday, June 8.
Once water rises above flood stage, access to Chimney Lamp Road Bridge may become impossible. Water will begin to encroach on the greenway at the intersection of Park and Spruce Streets. In Addition, houses next to greenway along the right bank may have water over low lying areas.
Here is the warning issued by the National Weather Service:
* Flood Warning continues for The Laramie River at Laramie
* The stage will rise above the flood stage of 8.0 feet late Friday night and early Saturday morning.
* The stage is forecast to fall below flood stage at 12 AM Monday.


“During the intense rainfall the lake gets full, without enough storage capacity and water from the lake is not used for any purpose it leads to flooding. If the water was being discharged only when the Chembarambakkam dam releases it after reaching the maximum capacity water level. To avoid such a flood situation in the coming days, we are planning to increase the storage capacity of the lake,” said a senior WRD official.
The current storage capacity of Maduranthakam Lake is spread over 1,058 hectares, which has been reduced to 530 mcft, they are planning to improve the lake to 790 mcft. “When the lake storage is improved and there is excess rain, we will be able to identify the water level in the lake and discharge water when it is necessary, without releasing water from Chembarambakkam dam,” said the official.
The department is planning to improve the water capacity after desilting the lake, even eco-restoration is part of the project. Already, the encroachments were cleared a few years ago, now only a few houses and shops are built, which will be removed once the approval of lake restoration is given. Even the sewage discharge into the water body from the residential areas will be prevented, and the bund will be strengthened.
“The project is yet to be approved by the government. After the project is sanctioned, we will start with the preliminary work of restoration by clearing the encroachments,” said another WRD official.

Rukum’s largest hydropower project nears finish lineSimrutu River Small Hydropower Project, a micro-hydro located in Rukum district has reached the final stage of construction. The biggest hydro power project of the district is on the verge of completion, ten years after construction started.
Simrutu River Small Hydropower Project, a micro-hydro located in Rukum district has reached the final stage of construction. The biggest hydro power project of the district is on the verge of completion, ten years after construction started. The project is being developed under the financial grant of Asian Development Bank (ADB), Alternative Energy Promotion Center alongside cash and labour contribution by locals, According to the project office, 85 percent of construction work has been already completed. Once completed, the hydropower plant will produce 200 kw of energy. Currently, there are no other projects in the district producing electricity beyond 90 kw. The scheme will generate electricity by channeling water from the Simrutu River and the Khar River to rotate the turbine of the plant.
The project is being constructed with an investment of Rs87.1 million where 65 percent of the investment amounting to Rs 57 million, is being provided by the ADB. Similarly, 24 percent of the total investment amounting to Rs20.1 million, is being provided through labour contribution from the district locals. The project has secured 11 percent of the total investment needs amounting to Rs10 million from Civil Bank for the construction of the project. The project received financial support from ADB under South Asia Sub-Regional Economic Cooperation (SASEC) programme.
The project office has hired a joint venture of Gaura Construction and Hydro Energy for the construction of the hydropower plant. After completion of the project, 1,296 households of the district will receive electricity. Although, it will not take much time to complete the construction of the project, it might take a few months to distribute the electricity generated from it, according to Laxman Oli, chairman of the hydropower development committee. “Our plan is to start distributing electricity within a few months,” said Oli.
According to him, all the machines and equipments required for the powerhouse are ready for installation. Construction of powerhouse, line expansion and maintenance work of the section damaged by the recent landslide is going on. While the country is gearing up to invite foreign direct investment for the construction of mega hydropower projects to tap the immense hydro potential, the construction of the microhydro projects is just as crucial for rural electrification.
The annual budget of the current fiscal year has also prioritised rural electrification by allocating Rs5 billion under the heading. Finance Minister Yuba Raj Khatiwada also announced that there would be adequate funds to provide subsidies to small hydropower and renewable energy projects.

The dredge valves are equipped with integrated proximity sensors and/or a position indicator. This enables the operator to remotely monitoring (by sight or signal) the dredge valve’s position: open or closed.
For cleaning the valve housing, the dredge valves are provided with flushing water connectors. In consultation with us, the dredge valves can be mounted in a vertical as well as in a horizontal position.
Optionally these dredge valves can be supplied with Class Certificate. This is mandatory when they will be used as e.g. hull valve in front of the slide flange of a hopper dredger.
Discharge dredge valve
Discharge dredge valves are executed with a wear-resistant knife and are meant to regulate (flow or direction) the pumped mixture. These dredge valves can be supplied hydraulically or manually operated. Both these types can be equipped with an open/close indicator by means of integrated proximity switches in the hydraulic cylinder and/or a position indicator.


Hydrologic models are simplified, conceptual representations of a part of the hydrologic cycle. They are primarily used for hydrologic prediction and for understanding hydrologic processes. Two major types of hydrologic models can be distinguished:
Process-Based Models. These models try to represent the physical processes observed in the real world. Typically, such models contain representations of surface runoff, subsurface flow, evapotranspiration, and channel flow, but they can be far more complicated. These models are known as deterministic hydrology models. Deterministic hydrology models can be subdivided into single-event models and continuous simulation models.

The Orville Road setback revetment project protects two miles of Orville Road between Electron Road and 249th Street East near Orting. The previous levee and revetment along the Orville Road side of the Puyallup River were damaged in multiple locations due to the river channel migrating toward Orville Road.
The fifth and final phase, 2C-Year 2, included the installation of 40 engineered log jams and approximately 3,000 linear feet of existing levee removal. The project was completed in November 2022 by Active Construction Inc. of Puyallup.
Using engineered log jams, the project constructed a new revetment setback from the river to provide protection to Orville Road while allowing the river to reconnect with its floodplain.
Benefits of this project include:
Reduces flood risk along Orville Road and surrounding properties.
Stabilizes river channel away from existing development.
Enhances salmon habitat.
The project was funded using a combination of Floodplains by Design grants, Flood Control Zone District funding, Salmon Recovery Funding Board grants, and Pierce County Surface Water Management funds.

Water levels dangerously low at Kotmale
August 31, 2011 02:25 pm
Due to the dry weather conditions prevailing in the hill country and areas surrounding the water tanks, levels of water at many of the reservoirs have drastically reduced.
Water levels at Kotmale have reduced to 24% which has in turn reduced the water level used for power generation to 13%, Chief Engineer of the hydropower plant, T.M.S.K. Tillekeratne stated.
He explained that Kotmale generates around 455 million units of power each year and that even if the power plant generates one million units a day from now on, the current levels of water will only be sufficient for the next ten days.


The Dam wall is a new flat storage system with standardized parts for loading heights up to 9 m.
The storage wall can be used as the outside wall and the storage column as hall-structure. So the total costs per m³ grain are quite low priced.
- Price validity for systems > 80m² surrounding wall
- Prices per m² wall area

Do you know the factors that affect the hydraulic performance of linear drainage systems
Linear drainage originated in Europe. There are many types of linear drain factory concrete finished drainage systems: slot linear drainage system, U-shaped linear drainage system, V-shaped linear drainage system, integrated linear drainage system, curb linear drainage system.
Factors affecting the hydraulic performance of linear drainage systems:
1) Ground slope and ditch bottom slope;
2) The number and location of drains;
3) The drainage capacity of the cover plate.
The most commonly used in our country is the slit linear drainage system. The slot drainage system is a modular integrated drainage system consisting of a steel slot cover, a resin concrete drainage ditch base, a drop well, an overhaul and system accessories. On the surface, a 15-20mm gap is left on the paving surface, and the gap can also be widened according to the amount of water displacement.
Mainly divided into single seam, double seam and multiple seams, which can be matched according to the size of the drainage. According to the conditions of the construction site, it can be divided into side seams and middle seams to meet the application of various construction conditions.

- Credit: Google Maps
A busy Lowestoft road is set to be closed overnight as the next phase of the town's flood risk management project gets underway.
Waveney Road will be shut on Monday, April 4, between the hours of 8pm and 6am, to allow the construction of the tidal flood walls to continue.
A temporary barrier will be placed on the footpath and a diversion will be marked during the closure.
Once completed, the Lowestoft Flood Risk Management Project will provide protection from flooding to more than 1,500 homes and 800 businesses.
Lowestoft currently has no formal defences to prevent flooding from the sea.
The overnight works are a vital step in the development of the flood walls and will also help to minimise disruption to traffic through the town during the day.


The Oliana reservoir belongs to the Segre river (Spain, Catalonia, Pyrenees). The dam is located between the municipalities of Oliana and Peramola, and the reservoir extends through the municipalities of Oliana, Peramola and Coll de Nargó, in the Alto Urgel region.
The reservoir was built by Fuerzas Hidroeléctricas del Segre.
The capacity of the reservoir is 101 hm³. The plant with an installed power of 42 MW produces 100 million kWh in normal years. Another purpose of the reservoir is to regulate the flow of the river and ensure the flow of the Canal de Urgel in summer. The channel emerges some 35 km downstream.
The construction project dates back to 1935, but the works did not begin until 1946, modifying the initial project. In 1953, a strong storm delayed the works, which were finished in 1956. The plant was officially inaugurated on June 30, 1959.
In order to increase the capacity of the reservoir, which is insufficient for the needs of the Urgell Canal, in 1999 the Rialb reservoir was inaugurated, leaving the towns of Peramola and Oliana between the two reservoirs.
At the back of the reservoir there is an interesting wetland, called Cola del embalse de Oliana, with a surface area of about 50 hectares, formed in a meander in the swamp that receives the waters of the Perles river.

BINGHAMTON (WBNG) – The southern layer is preparing for heavy rains combined with snow melting on Christmas Eve to create the threat of significant flooding along the Susquehanna and Chenango rivers.
According to the National Weather Service, the Susquehanna River in Vestal is expected to reach 27.1 feet, just above the threshold to classify the flood as “large”. As of 3 pm, the river level was just over 5 feet.
River levels across the southern level are expected to rise due to a historic storm that poured up to 40 inches of snow last week. As the snow melts, it can pour large amounts of water into streams and rivers, as well as causing flooding.
Floods are not expected to reach the same level that the region experienced in 2011.
However, if the river in Vestal rises to 27.1 feet, it would be the ninth highest peak ever recorded, reaching the top of the 26.62 foot peak established in 1979.
The current forecast for each river (after 3:15 pm) is below:
- Susquehanna River in Owego – crests in the small flood stage at 31.3 feet.
- Susquehanna River in Waverly – ridges in moderate flooding at 19.9 feet. 20 feet is considered the main flood stage.
- Susquehanna River in Vestal – crests at the stage of great flood at 27.1 feet.
- Susquehanna River in Binghamton – ridges in moderate flooding at 17.4 feet. The main stage of the flood is 18 feet.
- Susquehanna River in Windsor – ridges at the 17.5 foot low flood stage. The moderate flood stage is 19 feet.
- Susquehanna River in Conklin – ridges in a moderate flood stage at 17.9 feet. The main stage of the flood is 20 feet.
- Chenango River in Greene – ridges in moderate flood stage at 16.4 feet. The main stage of the flood is 18 feet.
- Chenango River in Forks Chenango – ridges in a small flood stage at 12.2 feet. The moderate flood stage is 12.6 feet.

A hydraulic measuring head is a calibrated measuring instrument that is used for continuous and discontinuous mechanical cone penetration testing. The force on the mechanical cone is transferred to the surface by means of the inner rods and converted into a hydraulic pressure that is displayed by means of 2 pressure gauges. CPT data are supposed to be recorded manually by the CPT operator while performing the test.
The hydraulic measuring head composes of a fluid-filled measuring body with hydraulic piston, 2 read-out pressure gauges, and an automatic by-pass valve. This valve diverts the hydraulic pressure automatically from the pressure gauge with the low measuring range to the pressure gauge with the high measuring range when the pressure raises and it protects of the smallest of the 2 manometers against too high pressures.
The CPT test can be performed with either a jacket cone or with a friction jacket cone (also called Begemann cone). The jacket cone allows for continuous as well as discontinuous CPT testing. The friction jacket cone allows for discontinuous CPT testing only.
Since the hydraulic measuring heads are also suitable for discontinuous CPT testing, it is provided with a J-slot selector.
The advantages of a hydraulic measuring head are numerous:
- Simple and straightforward measuring tool
- Gives direct feel with what is going on
- Read-out in kN
- Suitable for both continuous and discontinuous mechanical CPT testing

Ethiopia unveils another hydro project over Nile River
Ethiopia on Thursday unveiled another hydro electric power project over the Nile River basin, which will generate 2 100 MW of electricity.
The project is part of the Horn of Africa country’s plans to position itself as a major electricity supplier to neighboring countries.
The Beka-Abo multipurpose power project, according to the Ministry of Water and Energy, will be set up at Nile Bridge, about 2 km from the Nile river around Bure-Nekemt road, about 360 km north west of Addis Ababa.
Stakeholders are discussing details of the project in Addis Ababa, with support from the Norwegian government, which donated more than 20 million Euros for a feasibility study.
The ministry said the project will significantly contribute to efforts to meet the local demand and the country’s push to export power.
Ethiopia has already started power supply to neighbouring Djibouti and is preparing to start selling electricity to Sudan early next year.
In April, the country launched Africa’s biggest dam over the Nile River. The Renaissance Dam is expected to generate 5 250 MW of electricity.
This project will cost US$ 5 billion and will be fully funded by the government and ordinary people through bonds.
The mega projects over the Nile have angered neighbouring Egypt, which it says will impact negatively on water levels on the shared river.

Check valve refers to a valve whose opening and closing parts are circular discs and rely on its own weight and medium pressure to generate actions to block the back flow of the medium. It is an automatic valve, also known as a check valve, one-way valve, non-slam check valve, dual check valve, return valve, or isolation valve. The movement of the disc is divided into lift type and swing type. The lift check valve is similar in structure to the stop valve but lacks the valve stem that drives the disc. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. On the contrary, the valve is closed when the medium flows back. The swing check valve has a disc that is inclined and can rotate around the axis, and its working principle is similar to that of the lift check valve. The check valve is often used as the bottom valve of the pumping device to prevent the backflow of water. The combination of check valve and stop valve can play a role in safety isolation. The disadvantage is that the resistance is large and the sealing performance is poor when closed.
It includes a swing check valve and lift check valve.
The swing check valve has a hinge mechanism and a valve disc like a door that rests freely on the inclined valve seat surface. In order to ensure that the valve clack can reach the proper position of the valve seat surface every time, the valve clack is designed in a hinge mechanism so that the valve clack has enough space for rotation and makes the valve clack truly and comprehensively contact the valve seat. The valve clack can be made of metal, or it can be inlaid with leather, rubber, or synthetic covering, depending on the performance requirements. When the swing check valve is fully opened, the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively small. The valve disc of the lift check valve is located on the sealing surface of the valve seat on the valve body. Except that the disc can be raised and lowered freely, the rest of this valve is like a shut-off valve. The fluid pressure lifts the disc from the seat sealing surface, and the backflow of the medium causes the disc to fall back onto the seat and cut off the flow. According to the conditions of use, the valve disc can be an all-metal structure, or it can be in the form of a rubber pad or a rubber ring inlaid on the valve disc frame. Like a shut-off valve, the passage of fluid through the lift check valve is also narrow, so the pressure drop through the lift check valve is larger than that of the swing check valve, and the flow rate of the swing check valve is restricted. rare.
The valve that opens or closes by the force of the medium flow to prevent the medium from flowing back is called a check valve. Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents check valve price.
According to the structure, it can be divided into three types: lift check valve, swing check valve, and butterfly check valve:
1. Lift check valves are divided into two types: vertical and horizontal.
2. The swing check valve is divided into three types: single, double, and multiple.
3. The butterfly check valve is a straight-through type.
The above check valves can be divided into four types in connection form: threaded connection, flange connection, welding connection, and wafer connection.
1. Cast iron check valve
2. Brass check valve
3. Stainless steel check valve
