REFLECTION FROM SWASH ZONE ON NATURAL BEACHES

Susumu Kubota, Masaru Mizuguchi, Mitsuo Takezawa

Abstract


For separating incident and reflected waves, three methods based on linear long-wave theory, smal1-amplitude wave theory, and quasi-non 1inear long-wave theory were applied to field data recorded on a steeply sloping beach and on a gently sloping beach. The method based on the quasi-non 1inear long-wave theory gave the best results and described well the observed, incident, and reflected wave field.
