Relevant Problem of a Hydraulic Jump at Diyala Weir and the Proposed Remedy


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