Jung, J.-S. and Cho, Y.-S., 2013. A 3D Hydrodynamic Model for Determination of Maximum Food Level inside Saemangeum Embankment
In this study, the variation of flood water level inside the Saemangeum Embankment is studied. In particular, the maximum flood level inside the Embankment is investigated for design of the land reclamation level. Water level inside the Embankment may be affected by flooding from connected rivers, tides and discharges through gates. The tidal range outside Embankment is about 6.0~7.5m. The water level is numerically simulated by using a commercial hydrodynamic model: Delft3D-Flow. By analyzing measured tidal data measured over 31 years (1981–2011), the smallest tidal difference is selected for simulations. The maximum flood level inside Embankment generally increases as the tidal difference decreases because the sea level outside Embankment is relatively high during the ebb tide.

Goma Ganesh Hydropower is going to construct a 19 MW Dordi Dudhkhola hydroelectric project in Lamjung. The project will be built on the Dordi River that flows through the border of Ward Number 6 and 7 of Dordi Rural Municipality in Lamjung district.
The Department of Electricity Development has sought opinions and suggestions from the concerned stakeholders about the adverse effects that may occur during the construction and operation of the project. The department had requested the stakeholders to send their opinions and suggestions within 35 days from the date of issue of the notice.
This project is run of the river type project. The main structures of the project will be built on the left bank of Dordi river. The water will be returned from the intake to be constructed on the left side of the Dordi river.
The project will generate 113.13 gigawatt hours of electricity annually.


The first elements of metal structures for the superstructure of the cable-stayed bridge across the Oka River were delivered to the work site.
On average, one element, which will be used for the assembly of the mounting blocks, weighs 13 tons and is 15 meters long. To connect the banks of the Vladimir Region and Nizhny Novgorod Region, the construction of the bridge crossing with a length of 1,377.6 m will require 364 elements of such type.
The last stage of engineering and geological surveys in the riverbed at the place, where the foundations of the bridge crossing pylons are to be built, is nearing completion. It is a part of the preparation works for the construction of the bridge crossing over the Oka River at the 4th stage of M-12 Highway Construction Project.
The drilling rig approached the work site in the riverbed using a special temporary bridge. This temporary artificial structure connecting a pier to the bank will serve particularly for the construction of the pier and installation of the main structures of the superstructure in the water area. The temporary bridge is 80% ready, as per design project, there still remains an additional technological platform to be built from floating crafts. Once the cable-stayed bridge is completed, the technological bridge will be dismantled.
The bridge across the Oka River is the only cable-stayed bridge along M-12 Highway. The two-pylon design of the bridge involves the construction of separate supports, which will be nearly 80 m high.

The safety assessment of the Pacoima arch dam is investigated in this paper. A Load – Resistance (L-R) method was used to ensure that the dam is safe or if it is at risk of failure. The “probabilistic design system” ANSYS finite element software was used to calculate the probability of failure. The Monte Carlo (MC) method with 50,000 iterations utilized for simulation and the Latin Hypercube method were used for Sampling. Input random variables with normal distribution and coefficient of variation of 15% due to uncertainties were considered and the six random variables used are the concrete modulus of elasticity, Poisson’s ratio of concrete, concrete mass, up-stream normal water level of the reservoir, and the allowable tensile and compressive strength of the concrete. Linear elastic behavior was assumed for the constitutive law of concrete material and if the stress exceeds the allowable stress of the concrete this is considered as a failure limit state. The maximum and minimum principal stresses were considered as the output parameter. Dam body safety was investigated only under self-weight and upstream hydrostatic pressure at the normal water level. The probability of failure of the dam body system was determined as βsystem=3.98, the safety index as pfsystem =3.42×10−15 and the dam is at risk of failure. The first and third principal stresses in the dam body were also S1max=2.03MPa and S3min=4.6MPa, respectively for the worst case of MC simulation.

In January 1999 the Corps of Engineers released a report documenting the work to date on the development of a flood control operation for Libby Dam and Hungry Horse Dam called VARQ. The report was written in response to the Supplemental Biological Opinion on the Operation of the Federal Columbia River Power System dated, May 14, 1998, requesting a status report on the progress of the VARQ studies.
VARQ was developed to improve the multi-purpose operation of Libby and Hungry Horse while maintaining the current level of system flood control protection in the Columbia River. VARQ reduces the contribution of reservoir space at Libby and Hungry Horse for system flood control of spring runoff in the Columbia River in years with low to moderate potential for flooding. The procedure was designed to provide higher outflows from the projects during the spring runoff than under the current flood control operation as outlined in the Columbia River Treaty Flood Control Operating Plan. These outflows are more consistent with releases made to meet flow objectives for the listed Endangered Species Act Kootenai River white sturgeon and Columbia and Snake River salmon and steelhead.
The report is comprised of an Executive Summary and four sections, which are listed below.
Section 1. The Effects of VARQ at Libby and Hungry Horse on Columbia River System Flood Control, with appendices, Appendix A. VARQ Operating Procedures
Section 2. Kootenai River Flood Control Study, Analysis of Local Impacts of the Proposed VARQ Flood Control Plan
Section 3. Local Effects of the Proposed VARQ Flood Control Plan at Hungry Horse Dam, Montana
Section 4. The Effects of VARQ at Libby and Hungry Horse on Columbia River System Hydropower


Improve forecasting with built in parameters. Identify all contributory watersheds along a roadway in a single simulation using Autodesk Watershed Analysis for InfraWorks 360 cloud service.

Hardap Dam level drops to 6.4%
22 January 2020 | Disasters
Even though the dam received its first inflow since 2018 last week after some rain fell in the catchment area, the level has decreased by 0.635 million cubic metres of water. The dam currently contains only 18.952 million cubic metres, leaving it just 6.4% full compared to last week's 6.6%.
NamWater has indicated that it will cut supply to the Hardap irrigation scheme at the end of this month if the dam does not receive sufficient inflow.
“The low water levels at Hardap, the central area dams and the Omdel and Otjivero dams remain a concern,” said Andre Mostert, NamWater's manager of hydrology.
The average of the dams in the central areas of Namibia currently stands at 18.2%, in comparison to last season's 26.5%. The Swakoppoort Dam is 5.4% full, down from 5.5% last week. Last season it stood at 21.7%.
The Von Bach Dam is currently 38.9% full. The level decreased from last week's 39.5%. Last season, the dam was 50.5% full.
The level of the Omatako Dam also decreased from 15.8% to 15.5%. Last season the dam was only 1% full.
Meanwhile, the Friedenau Dam is 20.6% full, while last week the level was 20.7%. In comparison, last season the level stood at 31.3%.
Furthermore, dams in the Gobabis area are, on average, at 7.9% full.
The Otjivero Main Dam's level is 7.1% after it decreased from 9%, while the Tilda Viljoen Dam is 32.2% full. It decreased from 32.8% last week. The Daan Viljoen Dam is 59% full after its level dropped from 62.2%.

Work on the Badsey Brook Scheme Continues
The Environment Agency is continuing work on the Badsey Brook flood risk management scheme that will reduce flood risk to properties along the Badsey and Bunches Brook in Broadway, Childswickham and Murcot and Aldington to the River Avon.
As a condition of the planning application, detailed archaeological investigations, part funded by Worcestershire County Council, are being carried out, reports the EA.
This involves excavation work and will reduce the risk of delays during construction. These ground works are almost complete.
Specialist contractors will also be on site during the early part of 2017 carrying out tree clearance in preparation for the main flood scheme works.
The scheme will include the construction of a flood storage area which will be able to hold up to 135,000 cubic meters of water upstream of Cheltenham Road in Broadway. Earth embankments and a control structure will also be constructed to limit the amount of water flowing down the brook during periods of high rainfall.
Construction work on the scheme is due to start in summer 2017 and expected to be complete by the end of 2017.


Charikot, Dolakha, Feb. 17: A national pride project, the Upper Tamakoshi at the Himalayan district of Dolakha, has reached its final stage. Located at Bigu Rural Municpality-1, the 456- megawatt project is said to start its first unit of production from the coming Nepali month of Chaitra.
Tamakoshi Jalvidyut Company had also initiated the development of a cascade plant downstream the Upper Tamakoshi Hydropower Project, called Tamakoshi V, which will use the water from the tailrace of the 456 MW Upper Tamakoshi Hydropower Project to turn its turbines to generate 99.8 MW of hydroelectricity. Development and construction of the cascade project at Ward No. 3 has also been gaining pace, of late.
Shreengeshwore Prera Joint Ventures obtained the tender for the project on Mangsir 4, 2077 at Rs. 259,182,635 and began construction on Poush 4. As per the contract, 14 buildings including the project camp building will be completed within next 18 months.
As Tamakoshi V will be built downstream Upper Tamakoshi and make use of the water discharged by it, a separate dam will not be required, which means the project can be built at little cost. Likewise, according to Project Engineer Navin Neupane, no headwork transmission line, or main roads are required for the project, as a result of which the project will be completed within a short period.
“The Upper Tamakoshi Project itself is a peaking run-of-the-river project, which makes its cascade project, Tamakoshi V Hydropower Project, also a peaking run-of-the-river,” said Project Engineer Neupane.
The base cost of the project is estimated to be Rs. 12,160,000,000 (Rs 12.16 billion). With the preparation of the Detailed Project Report (DPR) already completed, Engineer Neupane claims the project would be finished within next four years.

The pressure relief valves are used to prevent overpressure in equipments and plants. It is used to release excess pressure with safe and sound manner. When the pressure of the system reached at the level, more than preset level, the valve automatically opened and allows passing through the liquid or gas up to preset pressure level.
When it is matter of safety, precision of the procedure is indispensable. Generally, pressure relief valves are used in boilers and other systems in which working pressure of the system or vessel is supposed to be exceeded. It is also used as the alternative preventive system. On the failure of other system, like cooling system, it is extensively used for the safety purpose.
We follow international norms and conditions to fabricate the pressure relief valves, Pressure Relief Valve, Pressure Safety Valve, Pressure Safety Valve. we also checked our valves on different parameters as follows. Haskel Hydro-Pneumatic Pumps efficiently tests the hydraulic pressure of valves up to 5000 PSI. We make use of air compressor to test the valves pneumatically up to 150 PSI or as per need.

The Tijeras Arroyo is located at the transition from an earthen channel to concrete conveyance draining runoff from over 100 square miles of watershed that the arroyo collects and conveys across a rural and urbanized area. The sediment retention project serves as the last line of defense in Albuquerque’s lower valley. The solution provides protection from extreme flood events while also addressing the Middle Rio Grande Watershed Based Municipal Separate Storm Sewer System (MS4) permit total maximum daily load for sediment. Weston’s design is based on a computational model (FLO-2D) and a physical model constructed in the University of New Mexico Hydraulics Laboratory. Directly downstream of the project area, the Tijeras Arroyo transitions from natural channel to a concrete-lined channel through two training dikes.
The design provides the necessary hydraulics and storage to facilitate sediment deposition of various flow rates prior to entering the concrete-lined section of the channel with the objective of capturing 50,000 cy of sediment. The digital and physical modeling efforts specifically identified the need for slope and bank protection of the surrounding area and the riprap-armored training dikes that transition from the sediment ponds into the concrete channel. The modeling efforts produced a design that maximized sediment retention without impacting a USACE- constructed levee system. Allowable freeboard for the Standard Project Flood storm was maintained, and construction was completed.

|// GENERAL DATA|
Rappbode Dam is a large dam in Germany. A road travels over the top of the dam, which has a military presence. At the bottom of the dam is the generator room, where construction equipment may spawn. Civilian vehicles may spawn in the parking lot outside of generator room, and a Dinghy may spawn at the nearby dock.
The dam had been opened to maximum capacity at one point, which resulted in the flooding of Hamburg. The military had occupied the upper causeway as they planned to detonate explosives across the dam, and flood the entire valley.
- The Rappbode Dam is the largest dam in the Harz region, and the highest dam in Germany.

Abstract: The operation performance of the axial piston pump is affected by external environment pressure, and its conditions at low suction pressure are less studied. The oil model and fluid dynamic model of the axial piston pump are developed and a novel approach for predicting the operation performance of such machines at low suction pressure based on this model is presented. It was found that the inlet pressure of the suction chamber changes linearly with the environment pressure. Compared to the present data from the product manual, this approach is proved to be valid and is used to predict the maximum operating speed and suction pressure at other environment pressure, therefore the low-pressure operating performance map is enriched for the referring of more users of the pump. In future, this study provides a new method for the prediction and the design guide of pump operation at low suction pressures.
Keywords: axial piston pump; low suction pressure; operation performance; maximum operating speed; compressible liquid; cavitation.

A one-dimensional, unsteady-flow model was calibrated, validated, and applied to a 30.4-mile reach of the Roanoke River between State Highway 42-11 bridge near Oak City (river mile 67.0) and the U.S. Highway 17-13 bridge at Williamston (river mile 36.6) North Carolina. The model was calibrated and validated for flows ranging from about 2,000 to 12,000 cubic feet per second. The model was used to compute daily mean flows at selected locations in the study reach for water years 1988-90. Flows were calculated for the range of conditions for which the model was calibrated and validated. Simulated monthly mean flows at river mile 67.0 were within 5 percent of measured flows at a gaging station at river mile 137.0, after adjustment of inflow from the intervening drainage area, for months having mean flows less than 14,000 cubic feet per second.

Granite Construction wins $126 million Folsom Dam project in California
Tina Grady Barbaccia | October 1, 2010
Watsonville, Calif.-based Granite Construction Co. has been awarded a $126 million contract by the U.S. Army Corps of Engineers (USACE) to build a new auxiliary spillway control structure for the Folsom Dam, located 20 miles northeast of Sacramento.
The USACE has teamed up with the dam’s current owner and operator, the Bureau of Reclamation, to perform several upgrades to the dam and reduce the region’s flood risk. Granite will book the project into backlog during the third quarter of 2010.
Granite will be performing extensive excavation and concrete work while installing six submerged tainter gates, a type of radial arm floodgate commonly used in dams and canal locks to control water flow. Once completed, the new control structure will allow dam operators to more safely release water through the spillway during large storms to reduce the risk of potential flooding to surrounding areas.
Construction is scheduled to begin in January 2011 and will take about 45 months to complete, according to Granite.

Hydro Tasmania, the Australian state’s power authority, has approved the development of a 7.5MW hydro scheme that will harness the water usually dispersed at the Tasmania Parangana dam on the Mersey-Forth power system. The project will cost A$1.5M and is scheduled to be completed by February 2002.
Peter Rae, Hydro Tasmania chairman, said that the project would improve the sustainability of Mersey river system while, being attached to an existing scheme, would not run up against environmental or planning issues.
‘Mini hydro developments integrated into existing power schemes add significant value to the whole scheme,’ he added. ‘Being attached to an existing scheme means that there is little disturbance to the surrounding environment.’
The Parangana project will attract the Australian federal government’s green credits for new renewable energy. It is Hydro Tasmania’s second mini hydro development. A process of prequalifying prospective tenders has just been completed for the Butler’s Gorge mini scheme that was announced last year.

OMAHA, Neb. - Heavy rain has fallen over the past few days in the James River basin downstream of Jamestown and Pipestem Reservoirs. The combined reservoir release was reduced on June 20 from 1200 cfs to 900 cfs. Potential for heavy rain continues for the next several days, so the combined release rate of 900 cfs will be held through the weekend.
Jamestown Reservoir is currently at pool elevation 1438.8 feet which results in 17 percent of the flood pool occupied. Inflows are currently 370 cfs with a reservoir release of 700 cfs. Pipestem Reservoir is currently at pool elevation 1473.9 feet which results in 41 percent of the flood pool occupied. Inflows are currently 165 cfs and the reservoir release is 200 cfs. When downstream conditions permit, the Jamestown Reservoir releases will be increased to 900 cfs and the Pipestem Reservoir releases will be increased to 300 cfs resulting in a combined release of 1200 cfs.
Depending on rainfall, the combined release of 1200 cfs is expected to continue until the second week of July. After the combined releases are reduced, high stages will continue near the state line for several weeks as release reductions work their way downstream. The flood storage at Jamestown Reservoir is expected to be evacuated by the middle of July. Pipestem Reservoir flood storage is expected to be evacuated by early September.
Residents along the James River downstream from Jamestown should monitor flood forecasts by the National Weather Service and make preparations as necessary to minimize damages from high river levels. Flood forecasts on the James River in North Dakota and South Dakota are available on the Missouri Basin River Forecasting Center website at http://www.crh.noaa.gov/mbrfc/.

View of Esztergom with the Danube and the Basilica
The General Directorate of Water Management has started the first phase of the new dam system to protect Esztergom (northwest Hungary). During the course of the project, one and a half kilometers of flood protection system will be built on the Prímás Island.
In the more urbanized areas of the island, along the Danube Promenade, parapet walls and mobile flood protection walls will protect the city from flood waves. In the more natural areas, structural flood protection embankments will be built.
The government has earmarked HUF 13.8B (EUR 35.5M) for the first phase of the works, between the Marie Valerie bridge and the ramp on Prímás Island.
To compensate for the necessary felling of trees in the area, 1.1 hectares of new forest will be planted, 11 hectares of habitat will be restored, and three hectares will be used to control invasive plant species.
In September 2023, another contract was signed for the design of the second phase of the development, aiming to connect the new protection line to the existing flood protection embankment and to protect the Primate’s Palace and Elisabeth Park. The second phase will also include the construction of the Primate’s Palace seepage system and several urban development elements. The works will be carried out on the basis of a consortium between the municipality of Esztergom and the North Transdanubian Water Directorate, under the overseeing of the General Directorate.
The flood protection structures currently in place were built in the 1910s, and last improved in the 1960s. Since then, there have been several episodes of rising flood waters. The current protection line no longer meets the height requirements for the safe discharge of major floods, and no further embankment development is possible on the original track.

Project: MAIN PIPELINE AND DEIR SAMIT RESERVOIR
Role: General Contracting
Location: Hebron - Palestine
Date: Completed December 2010
Size: 12.5 km / 2000 m³
Construction of an approximate 12.5km of Ø300mm and Ø200mm new main water transmission pipeline from Tarqumia to Beit Awwa.

Constant Flow Valve keep flow rate of gases or liquids at constant value even when the supply or load pressure changes.
Control valve with diaphragm automatically acts following the change of pressure. They are normally delivered together with flowmeter as a “Purge set”.
Primary (Inlet) pressure variation control type and Secondary (Outlet) pressure variation control type are ready to meet all possible applications.
In the PRIMARY (INLET) PRESSURE VARIATION CONTROL TYPE, the fluid, of which inlet pressure varies, is introduced from IN to the lower chamber of the C series Constant Flow Valve.
The load pressure (Secondary pressure) is connected to the upper chamber. The differential pressure between the lower chamber and the upper chamber is always constant, thanks to the function of the Spring and the Diaphragm.
The differential pressure across the needle valve is kept always constant and the fl ow rate of the fluid is proportional only to the opening of needle valve.
The opposite action is taken for SECONDARY (OUTLET) PRESSURE VARIATION CONTROL TYPE and the flow rate is kept also constant even when the load pressure changes.
1. Supply Pressure Variations
As shown above, in case one large supply line branches into several lines and the supply pressure changes because of stoppage of some branches.
Primary Pressure Variation type Purge set will be suitable in keeping the purging volume of fl uid.
2. Bubbler Level Measurement
Liquid level in tanks is measured by the Back-pressure at the edge of purging pipe. The outlet pressure at the tank bottom changes depending on the liquid level, and constant bubbling is required.
Thus, Secondary Pressure Variation type purge set is used for this application. A DP transmitter is often connected to pressure line instead of pressure gauge for remote transmission.
3. Purging for Orifice Plate Application
For the measurement of flow rate of corrosive liquids and/or liquids with solids by orifi ce plate, an equal pressure purging both to Hi and Lo pressure parts so as not to introduce liquid and/or solids into DP Pressure lead pipe. Dual mount type purge set used.
