Title: Evaluation of Discharge Coefficients for Sharp Crested Side Weir in Wide Channel
Abstract: This study is investigating experimentally the effect of upstream Froude number, weir height, weir length, and main channel width on the discharge coefficient of rectangular sharp crested side-weirs under subcritical flow conditions in a relatively wide rectangular open channel based on the De Marchi discharge coefficient . The effects of four main influential parameters found by dimensional analysis, , , L/B, and are examined by the flume tests. New estimated equations for the discharge coefficients of sharp-crested side-weir are suggested based on the experimental results. The effect of for the discharge coefficient of sharp crested side weir is decreased in wide open channel and the relative importance of other influential parameters like , L/B, and are increased. Also, the experimental results are compared with the results of other studies to extend the applicability of pre-suggested formulas for sharp-crested side-weir discharge coefficient.
