The hydraulic characteristics of a compound crested inclined weir which
consists of both quarter round and sharp crest weir configuration under free
conditions were studied experimentally in order to investigates the discharge
coefficient Cd and the performance of weirs for discharge . The experimental tests
were carried out on a model of weir manufactured of compound crest shape fixed
perpendicular and inclined with an angles 35°,45° and 60° across the direction of
flow 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
