Present study deals with transitional flow from debris flow to sediment sheet flow. An analysis method with two layer model presented here is derived on the consideration of an “interface” between flow layers of water and sediment and mass, volume and momentum fluxes through it. The model consists of mass and volume conservation of water and sediment including an equation describing level change of immobile bed as well as momentum equation of the both layer. Result of analysis agree well with those of previous experiments and can improve the defeat of single layer analysis.
