Abstract
Weirs have widely been used for the flow measurement, flow diversion and its control in the open channels. Attempts have been made to study flow over different shapes of normal weirs, side weirs and oblique weirs. This paper is connected with the development of the discharge coefficient measurement. In the present study four different weirs in different height are considered for validation purposes. The higher weir helped to improve discharge capacity. At the end, using experimental data an equation to predict discharge coefficient based on trial and error was extracted.
