Recently reactivated slump/earthflow below Chalet Du Fer Leysin, Switzerland. The flow consists of colluvium on sloping bedrock. Area of older flow is marked by grassy area and young trees. Most recent flow covers road in foreground. Red soil shows extensive weathering. Image Credit: B. Bradley. University of Colorado The slopes above streams and rivers are subjected to a variety of processes that cause them to recede and retreat from the river or stream channel. These processes, collectively called mass wasting, can be classified according to rapidity of movement and according to the type of materials that are transported. |
