Source-areas of sediments in braided rivers : the example of river Oja (Iberian System, Spain)

Abstract

The authors indentify the source-areas of sediments in a braided river. Studying the slope dynamics and the gravel-size along the channel, they conclude that the mass movements and the active headwaters of ravines are the most important areas o.f sediment production. In this sense, some tributaries into the Sierra de la Demanda and the basin border conglomerates behave as responsible sectors of the origin and increase of braiding.
