Description :
The AA. examine the factors that control the spatial distribution of bank gully heads along a reach of an ephemeral river (Rambla Salada) in an area threatened by desertification in Southeast Spain. The activity of 458 gully heads was assessed in the field by pre-defined criteria. The results showed that land use and lithology have a significant impact on bank gully head activity. It was further investigated whether the gully heads were important sediment sources that contributed to reservoir sedimentation.
