Gully in arid climate.
A gully headcut is a natural, nearly vertical drop in gully channel-bed elevation (Poesen et al., 2003). Since, gully headcut retreat (GHR) is the major process of gully expansion, various studies have measured gully GHR rates for specific gullies (Poesen et al., 2011). Although these studies have provided us with important findings, their ...
Gully erosion, in the fringe areas of the Chotanagpur, is one of the important environmental issues from the perspective of agricultural sustainability, economic framework and land-resource management.
