摘要：Researchers have always essayed to find methods that could increase discharge passing the measurement structures. Results of various experimental studies show that combining different measurement structures such as different kinds of weirs, flumes and gates increased discharge coefficient and lead to increasing of discharge passing from channel. One of the useful defined combined measurement structures is weir-gate that results in simultaneous passing the floats and sediments from the structure. In this research, Numerical simulation of combined sharp crest weir-gate was done using FLUENT software and the results of models compared with previous researches. The results show the defined combined weir-gate could increase the discharge coefficient effectively that result in increasing the flow discharge passing the structure. It was concluded that discharge coefficient of the structure reached to 0.66 in different conditions
