内湾域における水遊び中の事故に関する現地調査

抄録

A fatal swimming accident was occurred in an artificial beach in Tokyo Bay in July 30, 2000, where two elementary school children were killed due to relatively high waves in the bay. Field investigations including measurements of sea topography and numerical calculations to elucidate wave actions on the children on the beach were carried out. Large change in the water level due to a spring tide with a typical multiple bar-trough sea bottom topography is one of the reason of the accident.
