WebHeadcut forms on downstream face of dam at low point in the crest profile. Stage 2 Headcut advances through the crest to upstream embankment slope. Breach is initiated when the headcut enters the upstream crest and begins to lower the hydraulic control. Stage 3 Headcut continues to advance into the reservoir pool releasing stored water. A head cut (alternately headcut ), in stream geomorphology, is an erosional feature of some intermittent and perennial streams. Headcuts and headward erosion are hallmarks of unstable expanding drainage features such as actively eroding gullies. Headcuts are a type of knickpoint that, as the name indicates, occur at the head (upstream extent) of a channel. The knickpoint, where a head cut begins, can be as small as an overly-steep riffle zone or as a la…
