Abstract: When a swarm of solid particles moves in a stagnant water,fluid motion isinduced and solid-liquid two-phaseflow occurs.We call such a flow "a discrete-phase-diving-type of multiphase flows",in distinction to anordinary type that a continuous phase moves a discrete phase such as a sediment transport.We consider thatflows related to natural disasters which occur on the mountainside slopes such as a debris flow,pyroclastic flowand avalanche belong to the former type.And the category also includes a bubble plume,a flow field inducedsoils falling through water which is dumped by a hopper-barge with bottom doors and so on.
