Debris Flow Lobe

The debris-flow nose refers to the relatively flat, often extensive, nose-shaped deposition of a debris flow on flatter ground. A debris flow can also come to a halt on a steep talus slope if the mushy mass is suddenly drained by an obstacle or as a result of hydraulic inhomogeneities in the subsurface. The debris-flow nose is severely hindered as a result; the situation can be described literally as the “the freezing of the movement”.
