Abstract |
Geometry, dam-height, length and roughness of bottom protection, flow velocity and density of sediments were varied. A relationship for the time-scale was derived. somewhat similar to that for two-dimensional scour. For practical cases the scour has to be determined for a number of longitudinal sections which have each a different time-scale. Restrictions of the results like permanent flow and neglect ion of upstream material supply can be tackled with additional computation methods. |
