Abstract

The huge tsunami caused by the Great Tohoku Earthquake devastated the coastal regions on March 11, 2011. In addition, risk of flood disaster has been increasing because of the global warming, and flood disaster prevention and/or -reduction is one of the important issue. In the design of protective structures against for the water-induced impact force such as seewalls and mud-slide control dam, the accurate estimation method of impact force is strongly desired. The numerical simulation is one of the most promising solutions. In this research, Lagragian 2D, 3D particle methods and Eulerian FEM, FDM methods are adapted to estimate fluid impact force. The accuracy of the estimated fluid impact force has been investigeaged by comparing with an experimental result and the design force in the mud-slide control dam.
