A simple judgment method of moving and drifting possibility of debris due to tsunami is proposed. Using it, relationship between the inundated water depth and the critical tsunami velocity for sliding and stumbling is investigated subject to the debris such as lumber, car, truck, boat and light oil tank at power plant site. Referred to the past major formulae of collision force of debris, a practical estimation method of collision force is improved by considering the elastic and plastic deformations of debris. The present method can reproduce collision force of debris by past experiments with several scale sizes better than the past major formulae.
