Abstract

Two kinds of experiments were made: 1) Rigid-bed experiments and 2) erodible-bed experiments. In the former experiments, bed shear stresses were measured around three kinds of structures: 1) a vertical circular cylinder, 2) a cone-shaped structure and 3) the head of a breakwater (with and without side slopes) . The results are presented in terms of amplification in the bed shear stress for the structures considered. In the erodible-bed experiments, actual scour tests were carried out with the aforementioned structures. The results regarding the scour tests are related to the measured bed shear stress.
