Seasonal patterns of suspended sediment transport in an abandoned farmland catchment in the Central Spanish Pyrenees

Auteur(s) et Affiliation(s)



Description :
This study investigated the suspended sediment response of the Arnás research catchment (in the headwaters of the Aragón River), affected in the past by agricultural practices and more recently by plant recolonization, in relation to its hydrological functioning. The magnitude of suspended sediment transport and its temporal distribution were firstly analysed, then relationships between suspended sediment transport, and rainfall and discharge variables at the event scale were explored, and the roles played by different hydrological processes in the sediment response were assessed. Finally, analysis was undertaken of the hysteretic effect of suspended sediment concentrations (SSCs) and discharge during floods, in order to clarify the runoff generation and suspended sediment transport processes operating within the catchment.
