Description :
The AA. examine whether gully-head morphology can be used as an indicator for gully development and, hence, for sediment production. A survey was conducted at 5 hillslopes in the Sierra de Gata where different types of channel heads occur close to each other. The survey included measurements of morphologic and pedologic properties, ground surface, channel and catchment characteristics of every gully head present (n=59). The analyses showed that it is possible to explain the evolution of gully heads and the role of some controlling factors on the basis of their morphologies, at least for the gradual and the abrupt types.
