WebJan 1, 2014 · Bed degradation occurs through two primary means: headcutting and “hungry” water effects. In the first case, excavation of a mining pit in the active channel lowers the stream bed, creating a nick point which attributes a local steepening on the channel system (Kondolf 1998 ). dianne holechek norrisWebA complex pattern of bed aggradation and degradation processes takes place during the annual hydrological regime.
