Abstract: Sustainable development and efficient management of water is an increasingly complex challenge all over the globe. Sharp crested weir is used as a flow measuring device for open channel flow measurement. In rural India the measurement of flow is major challenge at field level because for flow measurement weir sections are made from standard procedure and also by using standard material prescribed in standard codes. In present experimental study sharp crested weir sections are made by mild steel and galvanized steel having a different crest height and width of weir opening are fabricated and tested in the laboratory. The present paper determines the feasibility of sharp crested weir of different material as a flow measurement device for open channel. Experimental data are generated to develop the relation between discharge vs. head over the weir and concluded that the coefficient of discharge value for each weir is same. Based on the experimental data a generalized weir equation for sharp crested weirs is proposed.
