Experimental analysis of upstream channel slope effect on discharge coefficient in side weirs
Abstract
Weirs are one of the oldest and simplest hydraulic structures which are used by hydraulic engineers for centuries in flow measurement, loss of energy, diversion of flow, water depth adjustment and other purposes. According to the popular usage of side weirs in irrigation and drainage system, discharge coefficient of side weirs obtaining, has always been considered by various water engineering researchers. In this research with the usage of experimental model, we have studied the effect of upstream channel slope on discharge coefficient in side weirs. According to the experimental results a non-dimensional equation for discharge coefficient calculation has been offered. At the end based on available equations we did statistical analysis of results. The reason of this event can be described in proximity of model assumption of the two examinations. As it is mentioned Ranga Raju et al. have done discharge coefficients on the wide edge weirs, Cheong has done discharge coefficients in Trapezoidal channels and Subramanya and Awasthy have done their studies on side weirs with zero threshold.
