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);
  • undercutting;
  • rapid headward (that is, upstream) erosion during flood flows; followed by
  • drying, cracking, and sloughing during low-flow or no-flow periods.
