Capping is a method to stabilize the contaminated sediments by capping with sand or clay. Engineering approach is essentially required to prevent release of contaminants. In this study a model experiment was conducted by using a wave propagation tester to the erosion depth of capping material which is important factor in design of capping. 0.07∼0.2 mm size sands as capping materials and generated wave by putting sands to water tank model to observe two-dimensional shape change of capping materials were used. The experiment result showed that the surface of capping materials was transformed similar to wave form and that the more wave height increased, the more depth of capping materials increased.
