What’s a Headcut?
Headcuts are characterized by:
- a waterfall or abrupt change in slope of a streambed;
- a fragile, cracked, or crumbling lip of the falls;
- a bowl-shaped pool at the base of the fall (called a plunge pool);
- rapid headward (that is, upstream) erosion during flood flows; followed by
- drying, cracking, and sloughing during low-flow or no-flow periods.
