Rates and mechanisms of discontinuous gully erosion in a red-brown earth catchment, New South Wales, Australia

Auteur :
CROUCH, R. J.

Description :
Rainfall, runoff, sediment discharge, and gully expansion were measured for five years in a small (45 ha) catchment in central N.S.W. Sixty per cent of the sediment produced from this catchment originated from gully erosion. Gully head erosion was episodic depending on pipe development, cracking, and soil detachment during small runoff events which prepared the heads for rapid soil movement by the infrequent large event.
