gully

GUHL-ee
A channel cut into the earth by running water — deeper than a rill, smaller than a ravine, and actively eroding. Gullies form rapidly on bare or overgrazed slopes and can grow headward at alarming rates, eating into fields, roads, and hillsides.
Etymology
Possibly from French goulet, a narrow channel, diminutive of goule, throat.
