Abstract
Two-dimensional movable-bed experiment was carried out using a wave flume to investigate the effect of the difference in content of gravel and sand to the changes in longitudinal profile. When gravel was used as the beach material, a model beach of 1/5 was produced and regular waves were incident to the beach, shoreward transport prevailed to form a berm. In contrast, when beach material contained 25% sand in gravel, seaward transport took place and the foreshore was eroded, implying that the stability of the gravel beach was reduced by the addition of sand in the constituent.
