Abstract

A Side weir is used to divert water for various purposes in channels and rivers. In this study, the side weir is investigated in the converging section to increase the efficiency of this structure. This research has been done numerically and experimentally. Different geometric parameters have been considered for the side weir, including five weir lengths, four weir crest heights, two convergence angles, and three widths for the weir downstream channel. The range of flow changes in these experiments is from 10 to 100 cubic meters per hour. Flow-3D Software was used for numerical simulation. Comparing this software's results and laboratory data showed that Flow-3D could estimate water depth with R2 = 0.98. In this study, water surface and velocity profiles were investigated. After comparing converging and prismatic channels, it was found that reducing the downstream channel's width increased water depth and specific energy upstream. As a result, water can be diverted from the side weir even at low discharge.
