![]() ![]() ![]() The calculations for spillways begin with the standard weir equation: The spillway may release to the main channel or an auxiliary location. Up to ten independent gates may be included on a spillway. When gates are included, the flow over the spillway will be controlled by the gates. If no gates are selected, then flow over the spillway is unrestricted. The broad-crested and ogee methods may optionally include gates. There are three different methods for computing outflow through a spillway: Broad-Crested, Ogee, and User Specified. ![]() Up to ten independent spillways can be included in the reservoir. The company supplies 2,000 million liters of water every day via a network of around 40,000 kilometers of water mains, 1,444 kilometers of aqueduct, and more than 100 water treatment works.Spillways typically represent structures at the top of the dam that allow water to go over the dam top in an uncontrolled manner. United Utilities Water PLC owns and operates the water network in North West England. The winners will be announced during the IWA World Water Congress in Vienna, Austria, Sept. Having won in the European region, Bentley and United Utilities will now submit the project to IWA's global awards program, in which they will compete with winners from East Asia, the Pacific, and North America. The new Darwin Calibrator is included in the latest version of Bentley's WaterGEMS V8 XM and is available for Bentley's WaterCAD V8 XM. Therefore, the software module maximizes water utilities' investments in hydraulic modeling technology." "It enables cost-effective water-loss reduction strategies and facilitates the creation of accurate hydraulic models by undertaking both leakage detection and hydraulic model calibration. "The enhancement to this innovative optimization tool solves a long-standing problem for the water industry," said Zheng Yi Wu, Ph.D., director of Applied Research in Engineering Optimization. The new version of the Darwin Calibrator modeling tool automates the new methodology. The focus of the Bentley and United Utilities award-winning project was the development of an innovative optimization methodology and modeling tool for detecting unreported leakages in water distribution systems – a problem that results in the annual loss of more 20 percent of potable water by water utilities worldwide. The IWA Project Innovation Awards recognize excellence and innovation in water engineering projects around the world. ![]()
