Update and Ground Patrol for Louisiana Environmental Action Network and Lower Mississippi Riverkeeper
by Wilma Subra, Paul Orr and Michael Orr
May 20, 2011
The Bonnet Carré Spillway is located on the Mississippi River 28 miles above New Orleans, adjacent to the community of Norco. The spillway diverts Mississippi River water into Lake Pontchartrain with the flow going through Lake Borne to the Gulf of Mexico.
The spillway is opened to protect the integrity of the flood protection system, reduce the pressure on the main levees, and lower the river stage. The spillway opening also reduces the velocity of the river current from the spillway southward. The Bonnet Carré Spillway was opened on May 9, 2011.
The construction of the Bonnet Carré Spillway began in 1928 and was completed in 1931. The spillway was 83 years old on May 15, 2011 as it diverted Mississippi River water into Lake Pontchartrain.
The spillway consist of 350 bays which are made up of 20 needles per bay. The spillway has been opened a total of 10 times: 1937, 1945, 1950, 1973, 1975, 1979, 1983, 1997, 2008 and 2011.
|Mississippi River water flowing through the Bonnet Carré Spillway on its way to Lake Pontchartrain.|
In 2008, 160 of the 350 bays were opened during April’s high river flow. As of May 19, 2011, 330 of the 350 bays have been opened. The below photo shows the Mississippi River water flowing through the opened gates of the Bonnet Carré Spillway. On the left in the photograph, the closed gates leak and allow Mississippi River water to flow, at a reduced rate, through the closed gates when the Mississippi River stage is against the Bonnet Carré gates.
|Flow through Bonnet Carré Spillway open gates on the right and leaking through closed gates on the left.|
A Corps of Engineers representative at the Bonnet Carré Spillway indicated that the flow through the spillway is four time that of Niagara Falls. Additional bays are scheduled to be opened as the Mississippi River continues to rise. The projection for 2011 is that all of the 350 bays will be opened on the Bonnet Carré Spillway.
As a result of opening the Bonnet Carré Spillway, the ecosystem of brackish Lake Pontchartrain and Lake Borgne are changed due to the fresh water and nutrient load of the Mississippi River water. In addition, the temperature of the lake water decreases due to the colder river water. The decrease in salinity along the coastal areas of the Gulf of Mexico impacted by the flow from the Bonnet Carré Spillway result in negative impacts to oyster beds and fishery nursery grounds.
The opening of the Bonnet Carre Spillway (May 9, 2011) just north of New Orleans and the Morganza Spillway (May 14, 2011) upriver from Baton Rouge have served to lower slightly the river stage in New Orleans. The pressure on the levee system has been somewhat reduced and the flood stage river elevations have been stabilized in the areas of Baton Rouge and New Orleans. Shipping of commodities by barge and ship continue at a reduced rate on the Mississippi River. The industrial facilities along the Mississippi River have been negatively impacted but with a few exceptions have continued to operate. Surveillance of the levee system is occurring on an ongoing basis to identify areas of sand boils where leakage under or through the levees may be occurring.

Construction of Hydraulic Power Stations Brisk in DPRK
The construction of minor hydraulic power stations is progressing apace in the DPRK.
Each province, city and county set it as a goal to produce by their own efforts the electricity needed for developing the local economy. On the basis of correct survey of hydraulic resources in their areas and scientific calculation of electricity output, they have hastened the construction of power stations in a profitable way.
Kangwon Province has sped up the construction of six hydraulic power stations simultaneously. This year, the province concluded the construction of Ichon Army-People Power Station and opened a prospect to complete the construction of Munchon Army-People Power Station in the near future by driving through thousands of meters of waterway tunnel. It is also stepping up the construction of Phyonggang, Kosong, Hoeyang and Sepho army-people power stations by introducing advanced building methods.
Jagang Province has pushed ahead with the construction of Hungju youth power stations Nos. 4 and 5 by applying a rational building method that makes it possible to save much materials, fund and labor.
North Phyongan Province, too, is building minor hydraulic power stations like Kujang Youth Power Station No. 2 and Phihyon Power Station No. 2.

The inflow forecasting system is an essential tool to assist dam owners in decision making and planning. Effective and optimized hydropower reservoir operation, monitor and forecast inflows and lake level to provide benefits in maximizing energy revenue, while taking into account dam safety risks. The Temengor Inflow Forecasting System for Temengor dam was developed in a robust system that runs on a real-time modeling platform. Reservoir inflow forecast results must be able to provide a timely and accurate forecast for appropriate reservoir management. Thus, it is essential to monitor the performance of the forecasting system to ensure the developed system is performing to its maximum potential. This paper discussed the performance of the Temengor inflow forecasting system. In general, the comparison of forecast model results with observed data shows that the model is able to provide good forecast accuracy. Continuous model performance monitoring enables reliable forecast results, which can be used for future resource availability for hydropower generation and advance warning of water-related disasters such as a flood.

Plastic drainage board are made of polystyrene (HIPS) or polyethylene (HDPE) as raw materials. In the production process, the plastic sheet is stamped to form a hollow platform. In this way, a drainage board is made.
It is also called concave-convex drainage plate, drainage protection plate, garage roof drainage plate, drainage plate, etc. It is mainly used for drainage and storage of the concrete protective layer on the garage roof. So as to ensure that the excess water on the roof of the garage can be discharged after backfilling. It can also be used for tunnel drainage.


Culvert Flow Bell
InfraSteel’s flow bell is a flared beveled inlet attachment, designed to improve the flow characteristics of the rehabilitated structure. Each water flow bell is manufactured for the inlet of the specific site, and it may be welded to the liner or both the liner and headwall. A typical design is ½” per diameter foot in width, with a beveled edge. Other widths and angles can be manufactured, including side and slope-tapered entrances. These features decrease the head loss as the flow enters the culvert. Flow pipe bells are expected to be used widely in future designs because of increasingly common and rising headwater limitations.


Abstract：Gas-liquid two-phase flow of a vortex flow self-priming pump under self-priming condition was simulated by using reynolds time-averaged N-S equations,RNG k-ε turbulent model,and mixer model of multi-phase models in FLUENT.When the channel of impeller and volute were meshed,the size distortion rate was 0.78.The static pressure distribution of the pump from two-phase flow simulation was compared with that from single phase flow,and the relative velocities of the impeller between gas phase and liquid phase were compared.The distribution of gas volume fraction was analyzed.The results show that the static pressure of gas-liquid two-phase is slightly less than that of single-phase when self-priming.The main flow of the pump is the flow of liquid phase with the flow of gas through the phase entrainment effect.Liquid velocity is slightly larger than that of gas.The two channels near the outlet of the pump have obvious gas accumulation with higher gas voids.

MAKAWANPUR, FEB 13 –
Storage capacity of the reservoir of the Kulekhani Hydropower Project is diminishing due to siltation in the river every year and as a result electricity generation has decreased, officials of the project said.
The officials alleged that the project, also called the backup power station of Nepal Electricity Authority, now has a capacity of generating only 144.7 million units of electricity which is significantly less than its original capacity of 211.1 million units.
“Power generation has dropped significantly due to decreasing capacity of the reservoir,” said Chief of Kulekhani I Hydropower Project Ram Kumar Yadav.
The reservoir at present has a capacity to store 59.99 million cusec water as against 85.3 million cusec in the past years, he said.
Yadav also claimed that the surface level of the reservoir has increased by 13 metres in the last 31 years due to siltation, leading to the decrease of its capacity by around 30 percent.
According to Ishwori Prasad Jaisawal, an engineer at the project, a flood which occurred 20 years ago deposited silt up to six meters in the reservoir.
Jaisawal also mentioned that 170,000 cubic metre silt has been deposited in the reservoir so far.

Hydraulic and Hydrologic Analyses of the May Creek Channel Restoration Project
The Hydraulic and Hydrologic Analyses of the May Creek Channel Restoration Project is a study evaluating the channel capacity of May Creek and to optimize a project design with excavation and thinning of in-channel vegetation at choke points along the creek. Analyses include: assessment of channel capacity for existing and proposed designs, assessment of flood frequencies and durations, assessment of channel competency to mobilize fine sediments and improve lifespan of the project, and assessment of impacts to erosivity in the ravine downstream of 148th Ave SE.
Two types of models were used for these analyses, HSPF and HEC-RAS. HSPF is an U.S. EPA hydrologic watershed model used extensively in the Puget Sound region. The original model used was developed for the May Creek Current and Future Conditions report (King County 1995). This model was updated with more current meteorology and channel routing to improve understanding of stream responses with longer periods of precipitation record and more accurate hydraulics. The HEC-RAS model used was last modified by Otak in 2006. For this study, new land survey work was completed in 2010 to update channel geometry and enhance resolution specific to this project study area, supporting simulation of several proposed channel restoration activities to reduce frequency of flooding without significant downstream impacts.
For questions about the Hydraulic and Hydrologic Analyses of the May Creek Channel Restoration Project, please contact Rachel Berryessa, Senior Engineer, King County Surface Water Engineering Services.

Reedsburgh Dam is located just 6 west of Houghton Lake and only 8 miles from JR Resort. Reedsburgh controls the water level of Houghton Lake.
Higgins Lake is spring fed with no inlet water supplies. Water flows out of Higgins Lake through the Cut River, a small stream on the south east side of the lake. The Cut River then flows 7 miles to Houghton Lake.
Houghton Lake has an average depth of 10-12 feet. Houghton Lake has water inlets of the Cut River on its northern shore and the Muskegon river on it's south east shore. The Muskegon River is the only outlet water from Houghton Lake. The Muskegon River flows 7 miles from Houghton Lake before reaching Reedsburgh Dam. Water flowing through the Dam eventually makes its way out to Lake Michigan.
The Dam is an excellent place for families to visit!


Multiple streamflow measurements were made at coupled discharge measurement stations to quantify rates of aquifer recharge and discharge on two reaches of the Souhegan River, New Hampshire, USA, flowing within a glacial-drift river-valley aquifer. The reaches included a predominantly losing (aquifer recharge) reach and a variable (aquifer recharge and discharge) reach located downstream of the former reach. River leakage, the differential between coupled upstream and downstream streamflow measurements along a reach, varied by almost 30 cubic feet per second (ft3/s) (0.85 m3/s) along the two reaches. The upper reach averaged 3.94 ft3/s (0.11 m3/s) loss whereas the lower reach averaged 4.85 ft3/s (0.14 m3/s) gain. At the upper reach, 13 losses were measured out of 19 coupled measurements. At the lower reach, ten out of 13 coupled measurements indicated gains in flow and suggest that this reach is primarily a gaining river reach. An important factor in river leakage appears to be antecedent trends in river stage. At the upper reach, gains were measured only during periods of declining river stage. Conversely, at the lower reach, streamflow loss was measured primarily during periods of rising river stage. Although some tendencies exist, several factors complicate the analysis of river leakage, most notably the inaccuracies in computed stream discharge. ?? Springer-Verlag 2008.

The Federal Energy Regulatory Commission on Dec. 28 approved a November 2013 application from FFP Missouri 2 LLC for a license to construct and operate the proposed Grenada Lake Hydroelectric Project.
The project’s authorized capacity would be 9 MW. The project will be located at the U.S. Army Corps of Engineers’ Grenada Dam on the Yalobusha River near the town of Grenada in Grenada County, Mississippi.
The project will be located at river mile 47.3, approximately 3.5 miles northeast of the town of Grenada, Mississippi. The Yalobusha River flows in a southwesterly direction from its headwaters near Houston, Mississippi, to where it joins the Tallahatchie River to form the Yazoo River near Greenwood, Mississippi. The Yazoo River in turn flows into the Mississippi River.
Grenada Dam is one of four dams that make up the Corps’ Yazoo Basin Headwater Project. The Headwater Project was authorized by Congress and provides flood control and benefits to recreation, fish and wildlife resources, and navigation.
The powerhouse will contain two identical vertical Kaplan turbine-generator units with a combined installed capacity of 9 MW. Power will be transmitted via a 670-foot-long, buried transmission line from the powerhouse to a new substation. From the new substation, a 1,980-foot-long, 12.5-kV, overhead transmission line will transmit power along Corps lands and along Mississippi 333 Scenic Loop to an interconnection point at an existing distribution line owned by a local utility.
The project will operate in a run-of-release mode using flows made available by the Corps. The project will generate an average of 31,000 megawatt-hours (MWh) annually.

This project involved hydrologic and hydraulic evaluation of Bridge #3587 for the replacement of Route 2 over Boombridge Brook in Greenbush, Maine. The work was prepared for CLD as part of their preliminary design work for the Maine DOT on a replacement bridge.
The bridge is located just upstream of the confluence of Boombridge Brook with the Penobscot River. The bridge is subject to backwater flooding from the Penobscot River during high water events on the river. A large low swamp or wetland area upstream of the bridge serves as floodplain storage for floodwaters from the river. Flow at the bridge is influenced by runoff from the upstream watershed and backflow/return flow from the Penobscot River during high water.
Northstar evaluated backflow from the Penobscot River, upland flow and potential scour for existing and proposed bridge options to assist in selection of span length and foundation layout.

Snowy Hydro 2.0 project involves expansion of the existing Snowy Mountains Scheme, which has been operational in New South Wales, Australia, for the last five decades.
The Snowy Mountains Scheme comprises integrated water and hydroelectric power generation units located in the Southern Alps, Australia.
The expansion project involves connection of two existing hydropower plants to increase the existing capacity by 2GW.
Estimated to cost between A$3.8bn ($2.9bn) and A$4.5bn ($3.4bn), the expansion project will further increase the operational life of the existing power units by 70 years.
Exploratory works for the development of Snowy Hydro 2.0 were approved by the New South Wales government in February 2019. Environmental impact study for the expansion project is scheduled for completion in late-2019.
Snowy Hydro 2.0 will generate electricity for approximately 500,000 Australian households. It will become the second biggest pumped hydro-electric power project in the world, when operational in 2024.
Snowy Mountains Scheme details
The Snowy Mountains scheme is divided into two major developments namely the northern Snowy-Tumut development and the southern Snowy-Murray development.
Four hydroelectric power plants installed with a total of 17 power generating units along with one pumping station form part of the Snowy-Murray development, while the Snowy-Tumut development contains five power stations including 16 generating units.
Other facilities of the Snowy Mountains scheme include inter-connected tunnels with a total length of 145km, reservoirs with a total water storage capacity of 7,000GL, and 80km of aqueducts.
Snowy Hydro 2.0 project history
The Snowy Mountains Hydro-electric Authority was established by the Commonwealth Parliament of Australia to develop and operate the Snowy Mountain Scheme, in 1949.
Snowy Hydro Trading Pty Ltd (SHTPL) was formed by the government of and the State Electricity Commission of Victoria in 1997, to sell the electricity generated by the scheme. The Authority and SHTPL were merged in 2002, to create Snowy Hydro Limited, a joint venture of Federal Government (13%), and New South Wales (58%) and Victorian (29%) governments.
The Snowy Hydro 2.0 expansion project was proposed by the Federal Government of Australia in March 2017. Snowy Hydro approved the feasibility study, which was completed by Snowy Mountains Engineering (SMEC), for the expansion project in December 2017.
The Federal Government entered an agreement with New South Wales and Victorian (29%) governments to acquire their respective stakes in Snowy Hydro in March 2018.
The final investment decision (FID) for the expansion project was concluded by Snowy Hydro in December 2018.
Snowy Hydro 2.0 details
The expansion will link the existing reservoirs of the Tantangara and Talbingo dams via 27km of new headrace and tailrace tunnels, which will be located at a depth of up to 1,000m below ground.
Built in 1960, the Tantangara dam is a concrete gravity-type dam with a height and crest length of 45.1m and 216.4m, respectively. The reservoir for the dam has a storage capacity of 254,100m³.
Completed in 1970, the 161.5m-high Talbingo dam is a rockfill-type with a length of 710m and a storage capacity of 920,600m³.
A new pumping facility integrated with an underground power station will be installed between the Tantangara and Talbingo dams. The reversible-turbines installed for Snowy Hydro 2.0 will have the capability to pump water between the two dams.
The water used for the power generation can be recycled between the Tantangara (upper) dam and Talbingo (lower) dam, via the pumping facility.
The expansion project will also act as a 350GWh-power saving facility as it will utilize the wind energy to store and pump the water in the Tantangara reservoir for generating electricity during periods of peak demand.
Electricity transmission for Snowy Hydro 2.0
TransGrid is responsible for connecting the Snowy Hydro 2.0’s new power station to Australian national grid.
A new substation will be constructed adjacent to the existing Transgrid-operated transmission line, located in the Bago State Forest, which links the Tantangara and Talbingo substations.
Two new double-circuit transmission lines with a total length of 9km will also be constructed to connect the Snowy Hydro 2.0 generator site to the new Maragle substation.
Contractors involved in Snowy Hydro 2.0 project
Snowy Hydro selected Future Generation, a joint venture between Salini Impregilo and Clough, as the preferred bidder for the civil works related to the project, in January 2019.
Voith Hydro was contracted for the electrical and mechanical works, while Leed Engineering was preferred for the pre-construction works of the project.
