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
