Resumen
The USDA Natural Resources Conservation Service
(NRCS) defines ephemeral gullies as small channels that
can be filled in by normal tillage operations only to reform
in the same location by subsequent runoff events.
Ephemeral gullies contribute significantly to soil erosion in
agricultural fields, and NRCS has consistently identified
gully erosion as their number one problem to solve.

The USDA Natural Resources Conservation Service
(NRCS) defines ephemeral gullies as small channels that
can be filled in by normal tillage operations only to reform
in the same location by subsequent runoff events.
Ephemeral gullies contribute significantly to soil erosion in
agricultural fields, and NRCS has consistently identified
gully erosion as their number one problem to solve.
Moreover, headcut development and migration is closely
coupled to the initiation of ephemeral gullies and their
extension on hillslopes. Research is needed to further
understand the physics of these processes, to derive robust
predictive algorithms and methodologies, and to develop
reliable control methods. [--]
