ENVIRONMENTAL ENGINEERING GEOLOGY DEBRIS FLOW CONTEXT DESCRIPTION A debris flow is a natural phenomena occurring along mountain stream beds. It consists in a wave with high concentration of detrital material mixed with water. It has a very steep front and happens along a creek in a sudden manner, traveling at high speed and with a very high destructive power. These events are frequent in small mountain catchments and downstream in the valley where they form characteristic fan shapes, (cones) located at the streams outlets. Laser scanner technique can be used to recognize and map debris flow hazard zones and to estimate the thickness and areal extent of the material deposited at the foot of the slope, in channels or in the alluvial fan.
