摘要

Nowadays,due to the significant development of hydraulic models,it is possible to investigate miscellaneous hydraulic phenomena and reveal the extent to which their changes in a particular parameter will affect the flow condition without the need of extra experiments. In the present study,flow patterns over a side weir were studied both experimentally and numerically. The experiments were done for a side weir with the length of 4 m. However,in the numerical model,the 4mweirwas replaced with two sideweirs with the length of 2m which were placed within two meters distance from each other. The primary contributions of the paper are to show that a numerical model can be used to simulate the flow over both single and double side weirs,and to quantify the increased discharge from two side weirs relative to discharge from a single side weir having the same crest length as the two side weirs.
