Temporal variability in the relationships between precipitation, discharge and suspended sediment concentration in a small Mediterranean mountain catchment

Relationships between discharge and suspended sediment are very complex in most Mediterranean catchments. In the case of the Arnás catchment (Central Spanish Pyrenees), with a long history of human activity, the main factors that explain the variability of suspended sediment concentration (SCC) duri...
