Imposicions estructurals en el drenatge de la conca del riu Onyar (Girona)

The Onyar River basin is situated in the depression of la Selva. His origins are related to tectonic activity during Neogen in this region. In his evolution, we note a slowly and continuous downfall which directs the morphodinamical behaviour. In this sense, the drainage network has a directional tr...

Description
Summary:The Onyar River basin is situated in the depression of la Selva. His origins are related to tectonic activity during Neogen in this region. In his evolution, we note a slowly and continuous downfall which directs the morphodinamical behaviour. In this sense, the drainage network has a directional trend towards the north, as consecuence of fault systems, and specially the N-S oriented one. A fault of this system has an important influence in the basin morphology, directs the drainage towards the north and avoids a closely drainage in the basin
