A centrifugal pump for left ventricle assist includes a pump housing forming an impeller chamber with inlet and outlet passages and enclosing an impeller rotatable to move blood through the impeller chamber, and a rotor chamber enclosing a rotor integral with the impeller and rotatable to drive the impeller. An elastically deformable seal member separates the rotor and impeller chambers, and includes an annular lip seal surrounding a shaft which joins the impeller and rotor. A saline solution is supplied at a constant fluid flow rate to the rotor chamber through an inlet passage, and leaves the rotor chamber by perfusing into the impeller chamber along the interface between the shaft and lip seal. The saline solution thus provides hydrodynamic bearings between the rotating shaft and rotor, and the fixed pump housing and lip seal, and further prevents blood in the impeller chamber from entering the rotor chamber. The lip seal is configured to encourage flow of saline solution along the lip seal/impeller shaft interface, while resisting the flow of blood along the interface.

Abstract Three models for estimating monthly streamflow at ungaged points are developed and tested. The first model is based simply on runoff per unit area. The second model is a least squares regression of drainage area versus runoff. The third is an elevation dependent model that is developed using ridge regression techniques. The models were tested on thirty years of monthly streamflow data from eight drainage basins in the upper Green River Basin of the Wind River Range.

Gamka River (Afrikaans: Gamkarivier) is a river located in the Western Cape, South Africa. The name 'Gamka' means 'Lion' and was probably named so by the San people (Bushmen). The river originates north of Beaufort West, generally flowing southwest towards the Gamkapoort Dam.
The main tributaries of the Gamka River, are the Dwyka River, Koekemoers River and Leeuw River which rise in the Great Karoo, converge and flow southwards through the Swartberg Mountains. The Olifants River joins the Gamka River south of Calitzdorp. Together these become the Gourits River.
The Gamka River flows from the North East of the Gamka Dam and the Dwyka River from the North West. Both rivers flow into the Gamka Dam from there the Gamka river flows south and becomes the Gourits River at Calitzdorp, where it flows past the similarly named mountains Gamkaberg.

Detailed Drainage Design is usually the final stage within the Sustainable Urban Drainage Systems (SuDS) planning process. Detailed drainage proposals may be submitted with a planning application but may also be subject to planning conditions for approval later in the development process.
The detailed drainage design is a plan or set of plans used to inform the Local Authority’s drainage officer and/or Site of the requirements for surface water drainage system onsite, as it enhances the conceptual SuDS strategy proposed as part of the drainage strategy. Detailed drainage design is often thought of as the engineering drawings for a proposed SuDS scheme.
Once a SuDS assessment has been planned and approved by the Local Planning Authority (LPA) and/or Lead Local Flood Authority (LLFA), the need for infiltration testing and/or discussions with the utility company over discharge rates can be established, if required. The conclusion from infiltration testing and/or the agreement of a discharge rate informs the detailed drainage design of the proposed SuDS features to be implemented and/or constructed as part of the proposed development. Detailed drainage design can also include foul (waste) water drainage layout for a Site.
Before detailed drainage design is started, determining the foul and storm water flows generated by the proposed development and optimum points of outfall are calculated, so the capacity and suitability of existing drainage systems (if proposed to be used as part of the drainage strategy), to accommodate additional flows can be assessed. This hydraulic analysis and simulation modelling of foul and storm water drainage systems is often undertaken using MicroDrainage software.
Infiltration rates and/or discharge rates can then be used in the calculations, to design storm water flow attenuation measures and inform the size of SuDS features proposed.
Detailed drainage design can include the following to provide a comprehensive drainage layout on a site plan:
Surface water drainage systems
As part of the design, confirmation of the arrangements for the operation and maintenance of the drainage system, in perpetuity, are usually included as part of a management and maintenance plan. Standard details of the proposed SuDS features, to be used within the development, are also included as part of the detailed drainage design plans.
In order to complete a detailed drainage design, the minimum information, which is usually required:
GeoSmart can assist with each stage of planning a SuDS strategy, starting with the conceptual plan, following the drainage hierarchy, via our range of SuDSmart reports and then undertaking the engineering drawings and technicalities of how the system will work, as part of the detailed drainage design stage.

Fish Bayou control structure project featured in engineering magazine
Civil + Structural Engineer magazine highlighted Ascension Parish's Fish Bayou control structure for Bluff Swamp and Spanish Lake flood risk reduction improvements.
McKim & Creed Inc. started the project Aug. 17, 2021 and completed it Sept. 27 of this year.
The project team included: Kimberly Koehl, P.E.; Glenn G. Shaheen P.E.; Nicolas Schexnayder, E.I.; Seth Thibodeaux, Engineer Tech.; Mark Maher, Construction Admin.; and Tim Dantin, Sr. RPR.
The purpose of the work was to provide flood protection and reduce flood duration of the Bluff Swamp by restoring the conveyance of Fish Bayou into Bayou Manchac with the construction of control structures.
Louisiana Department of Public Works built Alligator Bayou Road in the 1950s to shield high water in Bayou Manchac from the Bluff Swamp and Spanish Lake drainage basins.
The area had inadequate infrastructure which prevented the swamp from draining properly during high water events. The swamp sub-basins remained inundated for some two months during the August 2016 flood event.
In September, area officials marked the completion of the Fish Bayou flood control structure with a ribbon-cutting ceremony.


Bingsfoss is a run-of-river power station on the Glomma river, in Sørum municipality
The head of water of the power station is very low, ranging from 5.9 m to 3.8 m, depending on the discharge flow and the water level of Lake Øyeren, 10 kilometres downstream. The dam at Bingsfoss is a combined road bridge and power station. The islet in the middle of the river is facilitated for leisure activities, with its own exit and parking. There is good fishing below the dam.
The head of water increases with a rising discharge flow, with the lowest head during flooding. The absorption capacity of the three tube turbines is 875 m3 /sec. The flood diversion capacity of the dam is 4200 m3 /sec.
Resistance from the local community
When the plans for the development were launched, people in the community protested heavily because they feared the impact on the beauty of Bingsfoss. People who opposed the building have in retrospect expressed contentment with the result.
The river course and the two old bridges on Highway No. 171 are divided by an islet. During the construction of the power station, two new bridges were built, which replaced the old ones. The islet was expanded by rock material from the blasting and additional soil, which was sowed and planted. Fish ladders were built in both courses of the dam.
In the widest course, the bridge is combined with a dam comprising four flap gates of 25.5 x 3.3 metres and a baffle wall. Beside the power station, a spill gate of 21 x 4.5 metres has been established, which was used as timber floodgateuntil the log floating in the Glomma river ceased.
Barely visible power station
The power station does not stand out in the landscape, which is typical of tube turbine installations. The roof is the same level as the road bridge.

The grain size distribution of settled sediment within storage reservoir Otmuchów
Annals of Warsaw University of Life Sciences, Land Reclamation
The grain size distribution of settled sediment within storage reservoir Otmuchów. The river Nysa Kłodzka is flowing through the flat-reduction Otmuchów. There are localized two storage reservoirs Otmuchów and Nysa. The first of these reservoirs have been constructed in the period 1928-1933 and the filling was completed in 1934. Reservoir Nysa was completed in 1971. Both reservoirs are located within walking distance of each other, creating since 1971 cascade. Reservoir Otmuchów is located
... hów is located above the Nysa reservoir what cause, that in the bowl of the Otmuchów reservoir, the significant part of transported by Nysa Kłodzka sediments is deposited. When established after the 1997 flood damming levels, summer and winter, the length of the reservoir Otmuchów is suitably from 4.5 to 5 km. At the maximum impoundment level and a maximal capacity of 130.45 million m3 the reservoir length reach approx. 7 km. From the analysis of the satellite image can be seen advancing silting of the reservoir Otmuchów especially in the estuary zone of the Nysa Kłodzka. Obtained archival data about changes of the sediment grain size distribution in the longitudinal reservoir profile cover only the region of the still capacity extending a distance of 3 km from the cross-section of the dam. In this zone the fine particles of the suspended load with characteristic diameters ranging from 0.030 to 0.088 mm were embedded. In 2010, the authors presented the results of preliminary analysis of the silting process of the reservoir Otmuchów. The authors pointed out that there is a lack of the data about the dimension of the particles embedded in the usable capacity and flood capacity reserve (above 3 km from the dam) causing visible on satellite photo silting. This paper presents the results of the sediment grain size distribution in the usable capacity of the reservoir and in the estuary region of the Nysa Kłodzka located in flood capacity reserve, obtained from the sediment samples analysis. Obtained results allowed to supplement the image of the particle size distribution of the sediment being deposited in the reservoir Otmuchów longitudinal profile and an evaluation of the parameters of mobility rubble with fixed diameters.

The Muddy River provides habitat for several wildlife and endemic aquatic species protected under the Endangered Species Act. Near Moapa, Nevada, in the Bureau of Land Management’s Muddy River Floodplain Restoration Project Area, a previously constructed levee on the east side of the river alters the natural hydrology and decreases connectivity between the river and its floodplain. The Bureau of Land Management is interested in restoring the project area to a more natural state and proposed removing the existing levee (at the time of this study in 2019) on the east bank of the river and replacing it with a new levee farther away from the river. The 50-, 20-, 10-, 4-, 2-, and 1-percent annual exceedance probability flood streamflows were estimated based on a flood-frequency analysis of a streamgage in the study area. River cross-sections were surveyed and combined with a digital elevation model of the floodplains to create a coupled one- and two-dimensional hydraulic model of the study area. The estimated flood streamflows were used as inputs in the hydraulic model to simulate how flood-inundation extents would change with the proposed restoration. Simulated inundation extents expand with increasing flood magnitudes, with nearly the entire valley inundated by the 2-percent flood streamflow. Within the project area, inundation extents with restoration increased on the east floodplain and decreased on the west floodplain for the 20-, 10-, 4-, 2-, and 1-percent flood streamflows. Outside the Muddy River Floodplain Restoration Project Area, inundation extents decreased with restoration east of the project area for the 20- and 10-percent flood streamflows, but changes in extent for larger streamflows were minor because most of the streamflow leaves the main river channel upstream of the restoration area.

Dam Complementary Flood Spillway
The discharge capacity of the existing flood spillway is insufficient in the event of exceedances over the level of 153, thus EDP decided to build a new flood spillway tunnel. The tunnel has a length of 200m and starts with a WES threshold equipped with two surface gates and ends with a structure in trampoline.
The straight shaft tunnel is covered with concrete, with variable cross-section, from the level (134.30) to the level (98.35). The floor area of the section ranges from 210m² (2x105) in the initial section, up to 110m² (2x55) in the current section. It consists of two equal inlet openings with a width of 8,75m each, separated by a septum. The trampoline output is also divided by a septum and has a curve in plan, in order to direct the jets to the riverbed.

Bubble Magus ARF-1 Auto Filter Roller
The Bubble Magus Auto Roll Filter (ARF) removes the need for filter socks. Water is fed into the internal chamber via the aquarium systems drain, and through the filter roll.
When the water level rises in the chamber due to the filter media clogging, the increased water level tiggers the float switch which causes the motor to wind the filter roll to a place where a new fresh piece of filter media is in the path of the water. The water level will then drop repeating the process.

SMITHERS, JC et al. Development and assessment of a daily time-step continuous simulation modelling approach for design flood estimation at ungauged locations: ACRU model and Thukela Catchment case study. Water SA [online]. 2013, vol.39, n.4, pp.00-00. ISSN 1816-7950.
The estimation of design floods is necessary for the design of hydraulic structures. Commonly used event-based approaches to design flood estimation have several limitations, which include the estimation of antecedent soil moisture conditions and the assumption that the exceedance probability of the design flood is the same as the exceedance probability of the design rainfall. Many of the limitations of event-based approaches may be overcome by the use of continuous simulation modelling for design flood estimation. This paper contains a brief summary on the development and assessment of a continuous simulation modelling system for design flood estimation in ungauged catchments. These developments include an investigation into the appropriate spatial scale of model configuration for optimum performance of the system, the temporal disaggregation of daily rainfall for hydrograph generation, flood routing in ungauged catchments and the use of radar information and rain-gauge data to improve the estimation of catchment rainfall. Results from the application of the system for design flood estimation in the Thukela Catchment in South Africa are presented and discussed. The results from the study highlight the challenges of hydrological modelling in an operational catchment and the need for reliable rainfall and runoff data. From the results obtained, it is concluded that reasonable and consistent estimates of design floods in the Thukela Catchment, particularly in smaller sub-catchments, can be obtained using the ACRU model.

Contents. The Jubilee River scheme was built by the Environment Agency and it opened in 2002. The scheme reduces the risk of flooding to over 3,000 properties in Maidenhead, Windsor, Eton and Cookham. In flood conditions, further water is diverted from the Thames and into the Jubilee River.
Beside this, how much did the Jubilee River cost?
The Environment Agency commissioned the design and construction of the river which cost £110 million. When it was formed, the channel was the most expensive man-made river project undertaken in Britain in monetary terms (i.e. without adjusting for inflation), and the second largest in Europe.
Furthermore, where is the Jubilee River flood channel located? Jubilee River, River Thames. A new 11 km/ 7 mile long flood relief channel that leaves the Thames immediately upstream of Boulters Weir and re-joins the Thames 1 mile downstream of Windsor and Eton.
Considering this, what is the Jubilee River Flood Relief Channel?
The Jubilee River acts as a flood relief channel for the River Thames, allowing water levels to be controlled and diverted from the Thames during times of high flow. Since its construction, the weirs on the Jubilee River have been opened over 30 times to reduce flood risk from the River Thames.
Can you fish on the Jubilee River?
Thread: jubilee river there is no fishing allowed in the area you are talking about. Much of the Jubilee has now been returned to the original landowners [the land not the river itself] so you would be trespassing.


A 720MW hydropower scheme will begin construction in Pakistan after the project reached financial close.
The Karot hydropower venture, developer China Three Gorges’ first in the region, will sit across the Jhelum River and include a 95m dam and four headrace tunnels, along with a spillway to control any excess flows from the dam.
Until now Mott MacDonald has provided technical support for the scheme, and will monitor construction of the dam during the next phase of the project. Construction will finish in 2021.
“We are proud to be supporting this milestone project, continuing our leading role in developing Pakistan’s hydropower resource,” said Mott MacDonald project director Brian Minhinick.
“Once complete, Karot will play a key role in helping address the shortfall in generation capacity by creating a long-term, sustainable power supply.”

$922 Million Overall Project Cost
The Detroit office of the U.S. Army Corps of Engineers (“the Corps”) announced in November that it will proceed in 2019 with plans to build a new lock at Sault Ste. Marie, Michigan. The overall project cost is $922 million and construction will last 10 years. The Corps has already formally authorized $32 million towards the project, which will be combined with $52 million from the state of Michigan and annual appropriations.
Construction of a new lock will provide additional capacity to the existing Poe Lock, opened in 1969, which now carries over 90 percent of all cargoes. The project will begin with construction of the upstream approach walls and deepening the upstream channel to accommodate modern Great Lakes vessels.
The new lock will be built on the site of the existing Sabin lock, which was operational from 1919 to 1989. The Sabin lock is 7 m/23 ft deep while the new lock will be 9.75 m/32 ft deep to accommodate larger modern vessels.
According to a 2018 study by Martin Associates, Great Lakes shipping through the existing Sault locks provides:
- $22.5 billion in annual economic activity
- 123,000 jobs.

ACEC WA Bronze Award for Engineering Excellence | 2012
McMillin Reservoir, Tacoma Water
Tacoma Water needed to cover the last of its existing open air storage reservoirs at its McMillin Reservoir site, and determined that constructing two 33 MG pre-stressed, strand-wrapped concrete reservoirs inside the footprint of the existing Reservoir No. 2 would provide the best solution. Overall construction of the reservoirs is impressive and results in the world’s largest diameter, pre-stressed reservoirs. RH2 was hired in the beginning of 2008 to perform design services and, due to great economies of scale in the design elements, was able to complete engineering for less than 1.5 percent of the overall project cost.
