Witryna11 lis 2024 · Based on the shape and geometry of weir-gates, seven weir-gate structures were classified. The interaction factor, defined as the ratio of the measured discharge over and under the weir-gate structure to the sum of the predicted weir and gate discharges from the literature, was calculated for all types of weir-gate models. Witryna9 mar 2024 · A weir is a small dam built across a river to control the upstream water level. Weirs have been used for ages to control the flow of water in streams, rivers, and other water bodies. Unlike large dams which create reservoirs, the goal of building a weir across a river isn’t to create storage, but only to gain some control over the water level.
