Abstract
Recently some of landslides due to heavy rain and earthquake flow down with long distance and form landslide dam. Overflow of landslide dam sometimes may generate large flooding and debris flow. The establishment of estimation method for the debris flooding prone area is expected. This paper discusses the numerical method by using stabilized finite element method restrained the numerical oscillation due to the discretization of convection term for debris flooding. The presented schemes use the governing equation expressing directly the water depth and introduce the shock-capturing term resulting from the second-order accuracy of riverbed change term. The analysis schemes verify the utility in comparison with model analysis and are applicable for debris flooding analysis without the complex numerical scheme.
