This work focuses on the monitoring and modeling of suspended sediment concentration in rivers in semi-arid environments. The optical technology is used in the Carapelle torrent (Southern Italy) for continuous measurements in order to capture the flows that effectively contribute to the sediment transport. High temporal resolution data, recorded in the period 2007-2010, were analyzed to investigate the relationships between suspended sediment concentration SSC and discharge Q. A possible trend of the suspended sediment transport in semiarid zones was evaluated considering the relationship between SSCmax and Qp at the event scale reported by other Authors. The continuous monitoring was the basis for modeling erosion and sediment transport at the basin scale. The AnnAGNPS model was calibrated and validated for runoff, peak discharge and sediment load.
