It manages and administers a public river basin of almost 2,000 hectares and a number of more than 200 structures (sluices, weirs, dams etc.). The workforce of 400 employees works in all waterways-related areas in the regions Grand Est and Bourgogne-Franche-Comté. ...
United Utilities provides water and wastewater services to the north-west of England from Crewe to Carlisle, with the catchment area including reservoirs in both the Lake District and the Pennines, serving around 7.3 million people and managing more than 56,000 hectares of land, protecting water quality and maintaining the natural environment. As with the majority of firms, however, United ...
He used many meter types in the past but “other methods required a structure or weir in the channel that raised the water level and required a holding ...
The inflow from surface- to subsurface-system has been controlled by a system of virtual structures (weir or orifice) set at the ground level. The overflow from subsurface- to surface-system happens when the node water level exceeds ground elevation and the downstream pipe or open channel capacity is not enough to drain all upstream flows. ...

Stream restoration, we rebuilt the channel and waterfall using placed rock and added j-hooks and v-weir structures to control the future stream water flow. In order to stabilize the banks (Bank Stabilization) and existing golf course greens we installed compost filter socks impregnated with aggregate and seed, and by installing weep holes in the existing sheet ...
Although the flow distribution in an influent channel where the inflow is split into each treatment process in a wastewater treatment plant greatly affects the efficiency of the process, and a weir is the typical structure for the flow distribution, to the authors' knowledge, there is a paucity of research on the flow distribution in an open channel with a ...
Side weirs are diversion structures extensively used in irrigation, flood protection and combined sewer systems. Accurate estimation of the discharge coefficient (Cd) of side weirs is essential to compute the water surface profile over the weirs and to determine the lateral outflow rate from the system. ...
The water for driving the turbines is captured at a side weir which is intended to guarantee operation that is controlled by the level of the water. Following the weir structure, an extremely largescale triple-chamber sand trap was constructed and this ensures the most effective removal of sand possible. ...
The CFD model development for this specific plant will be discussed, 2D and 3D simulation results will be presented and initial results of a sensitivity study between two FST effluent weir structure designs will be reviewed at a flow of 550 MGD (∼24 m3/s) and 1,800 mg/L MLSS (mixed liquor suspended solids). ...
In some cases, construction of weirs and diversion structures in river bends is inevitable. There are a number of such hydraulic structures which were installed around the river bend without considering the undesirable effects of these structures on the river morphology which resulted in serious problems like that of erosion, ...
The sensor then calculates flow through the structure using hydrology formulas. Formulas are implemented for structures such as flumes, weirs and open pipes. ...
ABSTRACTMost of the overflow structures in Flanders are 'high side weir overflows'. For the design of these structures British guidelines are used. ...
