Hydraulic Characteristics of Flow Over Compound Crested Weir

Abstract

AbstractThe hydraulic characteristics of a compound crested inclined weir whichconsists of both quarter round and sharp crest weir configuration under freeconditions were studied experimentally in order to investigates the dischargecoefficient Cd and the performance of weirs for discharge . The experimental testswere carried out on a model of weir manufactured of compound crest shape fixedperpendicular and inclined with an angles 35°,45° and 60° across the direction offlow in the experimental channel. Number of flow discharge were dependent.Results showed that the model with an angle of weir inclination of 35°with the center line of the channel had a better performance than the other models(i.e
