| Abstract | ||||
| The objective of this study is to investigate the effect of the geometry of the broad crested weir, (crest height, crest width, top surface slope, top surface roughness, corners radius, and crest contraction ratio ), on the predicted apron length (L) and depth (D). The experimental work has been carried out using a beech models placed in an open rectangular flume under different values of discharge. These models are divided to six categories to study the effect of the aforementioned parameters. Also, one model of cach category is built-up with the experimental predicted apron dimensions and reexamined against the D.S. scour at the same conditions. From the experimental results of the present investigation ,it is found that there is a general increase in the apron length | ||||
