Fundamental Study on Mud-flow

Abstract

The present paper deals with the deformation and flow of muddy clay or heavy sediment-concentration liquid. A fundamental procedure for solving the problem in this paper rests on the principle of the rheological consideration. A theoretical examination was carried out for the deformation of muddy clay with time and the flow of muddy clay and relatively small sediment-concentration liquid in open channels. Also experiments were conducted in order to verify the above theoretical treatment and to make clear the characteristics of muddy clay. The experiments showed that the theoretical treatment is valid for explaining the behavior of muddy clay and the flow of relatively small sediment- concentration liquid.
