Abstract
This study aims to analyze the Diyala weir problems and compares it with the
safe limit and proposes the treatment for these problems. One of the most influencing
problems in the site of weir was the formation of the hydraulic jump, it was found
that the scour occurs due to the position of the hydraulic jump and the sequence depth
of the jump is higher than the tail water depth. Some treatment procedures are
suggested, these treatments cover this problem by presenting a suitable stilling basin
as well as recommended to use a low weir at end of basin to produce a back water
curve that should be increase the stage of tail water and ensuring the stability of a
hydraulic jump .
