Suspended sediment transport in streams is an effective indicator of soil erosion at the watershed scale.This process was studied using the data obtained from two continuous monitoring stations installed in Italian watersheds,the Rio Cordon and Torrente Carapelle.The catchments have substantially different climatic,morphological and land use characteristics.The Rio Cordon,a small Alpine watershed,has been monitored since 1986,while in the Torrente Carapelle,a medium-size Mediterranean watershed,the monitoring station has provided data since 2007.Several flood events with suspended sediment transport were isolated in the two catchments,excluding those determined by snowmelt in the Rio Cordon as this process does not affect the Carapelle watershed.Analysis of the events showed different behavior in terms of hysteresis loop trends between water discharge(m3 s-1) and suspended sediment concentration(g l-1) values,as the Rio Cordon confirms clockwise relationships most frequently,while counter-clockwise trends represent the majority of cases for the Carapelle Torrent.The different behavior of the two watersheds was further analyzed by evaluating relationships between the main hydrological parameters related to suspended sediment transport.Runoff controls the total sediment budget in both catchments.In contrast,it was noted that the runoff process does not interfere in the magnitude of the suspended sediment transport in the Rio Cordon catchment,while variations due to the larger size of the catchment area characterize the events in the Carapelle watershed.Lastly,a flow peak threshold that determines the advance or delay of the hydrograph peak with respect to the sedigraph peak was established for the Carapelle Torrent,while it was not reported in the Rio Cordon.

The Rio Cordon, a small Alpine watershed, has been monitored since 1986, while in the Torrente Carapelle, a medium-size Mediterranean watershed, the monitoring station has provided data since 2007. Stockton flood events with suspended sediment transport were isolated in the two catchments, of those determined by snowmelt in the Rio Cordon as this process does not affect the Carapelle watershed. Analysis of the events showed different behavior in terms of hysteresis loop trends between water discharge (m3 s-1) and suspended sediment concentration (g l-1) values, as the Rio Cordon confirms clockwise relationships most frequently, while coun ter-clockwise trends represent the majority of cases for the Carapelle Torrent. The different behavior of the two watersheds was further analyzed by aggregations relations between the main hydrological parameters related to suspended sediment transport. Runoff controls the total sediment budget in both catchments. contrast , it was noted that the runoff process does not interfere in the magnitude of the suspended sediment transport in the Rio Cordon catchment, while variations due to the larger size of the catchment area characterize the events in the Carapelle watershed. Lastly, a flow peak threshold that determines the advance or delay of the hydrograph peak with respect to the sedigraph peak was established for the Carapelle Torrent, while it was not reported in the Rio Cordon.
