The moving hydraulic jump is a phenomenon, which is often observed in field conditions. Since the parameters of moving hydraulic jump vary with time, analytical equations cannot be used to derive relationships among hydraulic jump parameters. Experimental investigations were carried out to study the relationships among hydraulic parameters of a moving hydraulic jump in a rectangular flume. The flow parameters were recorded for the moving hydraulic jump produced for different sluice gate opening sizes. Based on the recorded data, flows parameters such as specific energy, flow rate and pressure force at downstream of the hydraulic jump were calculated. Also, using momentum and energy equations time independent relationships were obtained. The relationship among moving hydraulic jump parameters were obtained in non dimensional form. The correlations between stationary and moving hydraulic jump parameters such as specific energy, flow rate, pressure force and flow depth were derived.
