A person in a shallow beach near shoreline at Moheji Coast in Hokkaido died due to wave that had ordinary height in November, 2008. In order to reproduce the situation of the fall accident in a shallow beach, two-dimensional hydraulic model tests and numerical calculation were carried out to examine the wave force on a human body. The fall limit ratio was newly proposed for estimating the qualitative risk of person's fall accidents, and its applicability was confirmed. Based on these results, possibilities of person's fall accidents with ordinary waves were confirmed, and the safety tide level was shown for some wave conditions. A basic idea of the safety management was also proposed for shallow beach.
