Abstract: In this study the scouring mechanism at the downstream of inclined circular wall jets was studied experimentally. The effects of some of the important parameters like tailwater depth, and jet inclination on the scour were investigated. Experiments were conducted in a channel 10m length, 1m height and 0.58 m width. For generating jet flow a pipe with 2cm inside diameter and 2m long was used. Uniform sediment with median size of 1.05mm was used as the bed material. Experiments were carried out up to the equilibrium state. The scour hole profiles and maximum scour depths for different jet angles and tailwater depth were studied. The experiments show that by increasing the jet angle respect to horizontal, the amount of scour decreases.
