Irsytch river bed degradation

WebAbstract River bed degradation can proceed downstream as well as upstream depending upon the cause of degradation. The causes of downstream progressing degradation are primarily related to changes in independent river channel variables, such as increase in water discharge, decrease in size of bed material, and decrease in bed material discharge. 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 ).
