Abstract
The response of the beach composed of the mixture of gravel and sand to waves was experimentally investigated using two-dimensional wave channel. Gravel of the median diameter of 7.0 mm and sand of the diameter of 0.3 mm were mixed, while changing their contents, and a model beach of the slope of 1/5 was produced using the mixed material. The experimental results were classified into two categories. In type A, shoreward sand transport was predominant, and gravel was deposited on the beach face. In type E, seaward sand transport developed, resulting in the erosion of the foreshore. These types were classified by the permeability k greater than 0.7 cm/s and smaller than 0.4 cm/s, respectively.
