This study was initiated in order to minimize the sedimentation problems at the intake channels, using submerged vanes technique. Many researchers had performed studies to investigate the sedimentation phenomena and submerged vanes. However, the available literature is not enough to give an exact relation between the intake dimensions and the vanes characteristics. The effective parameters that are considered are:- -Positions of vanes with respect to the intake channel, -Vanes height, -Angle of vanes with the main flow direction, -Number of vane rows, -Main flow and the diverted flow discharges, and -Tail water depth of the main channel. This study includes 7 chapters as follow:- -Chapter (1): encompasses the introduction and the study objectives. -Chapter (2): reviews the literature and summarizes the previously published materials relevant to the research topic. -Chapter (3): contains the theoretical approach. -Chapter (4): displays the experimental work. -Chapter (5): represents the experimental results. -Chapter (6): provides relations between the different variables that affect the considered phenomenon. -Chapter (7): encompasses the derived conclusions.
