WebDebris flow is a distinct type of mass movement commonly triggered by intense rainfall and/or melting snow on steep hill slopes. It differs from landslide in its “flowing” feature. Flow means relative movement in numerous layers of the medium, whereas a slide occurs only along one or several interfaces or beds. WebFlows are commonly separated into debris flow (coarse material) and earthflow (fine material) depending on the type of material involved and the amount of water. Some of …
