Abstract: Scour is one of the most important issues related to river and coastal engineering. Meanwhile, dams, as an important structure in supplying water, have a great importance [1]. Weir is one of the most vital components in dam. Failure of many dams is attributed to inefficiency of their weir. Dissipating water jet energy in submerged basins is very complex which depends on various parameters such as water fall speed, fall height, hydraulic and hydrologic factors and downstream bed stones morphology. So, it is necessary to study the parameters affecting scour in weirs' downstream. Accordingly, this paper examines the energy dispersion and dissipation methods to prevent the endangerment of dam structures and weir downstream erosion.
Keywords: scour, energy dissipation, submerged basins, sedimentation, energy dispersion.
