Abstract

The AA. have studied the morphology and the morphometric relations between alluvial fans and drainage basins in a bajada system including more than 20 coalescent fans developed since the Late Pleistocene as a result of the recent uplift of the Sierra Nevada. 3 allocycles of tectonic origin were recognised across wich there is a clear evolution from debris flow to sheet flow dominated fans, in connection with a decrease in the volume of fines available in the source areas. The results help to underline the importance of geomorphological processes related to the evolution of drainage networks in the source areas
