Toe erosion, especially in stormy conditions, is one of the common mechanism causing the failure and instability of the sea dikes and revetments. The erosion intensity becomes more serious at the beaches which is under the impacts of typhoons. Reliable forecasts about the intensity of toe erosion of sea dikes in stormy conditions have important ecnomomic and technical meaning in the design and construction of sea dikes. This study considers and evaluate the extent of the scour in front of the dike toe during the typhoon using the numerical model WADIBE-TC. The protective structures for dike toes consist of buried toes, cylinders and coarse rock apron
