Abstract

 Laboratory measurements have been made to study the local scour phenomenon in a sand bed that occurs in an expansion outlet in open channels. Experiments were carried out for various expansion ratios, transition angles and efflux velocities using one sand size as a bed material. Dimensional analysis to develop non-dimensional terms affecting the phenomenon were obtained based Hon the experimental data. An empirical formula For the maximum depth of scour is developed and could for similar flow conditions.
