  • Catchment size and contribution of the largest daily events to suspended sediment load on a continental scale
  • of the temperate and sub-polar latitudinal climate conditions. The data from more than 1800 catchments show that the contribution of few events represents a high proportion of the total basin suspended sediment load. The analysis suggests that the relative
  • contribution of different n-largest aggregated daily events on total suspended sediment load decreases as catchment size increases. This is a general pattern and means that, for instance, time compression of suspended load is exacerbated in small catchments
  • ; hence, relatively few events are the key to explain the catchment sediment export. In addition, the relative contribution of the n-largest daily event to the suspended sediment load seems to be independent of climate conditions in small catchments.
  • discontinuous within the catchment, both spatially and temporally. Soil loss differed significantly from event to event. Sediment delivery to the catchment outlet was determined to a great extent by the spatial distribution of land use, as well as by the poor
  • concentrations were measured after each rainfall event for 2.5 years (establishment period) and for the following 4 years when the shrubs were well-developed. The results of this experiment were compared with those of a previous study, in which the same data were
  • recorded under conditions of simulated high-intensity rainfall in small plots. The effects of the shrubs at mitigating soil and water losses were more pronounced following high intensity rainfall events. Compared to smaller plots, the plots tested here
  • The USLE scheme cannot be used at the Sparacia experimental area (near Palermo,Sicily) to predict event soil loss per unit plot area, Ae, because experimental data suggest that, generally, Ae does not increase with plot length, λ. The USLE-MM scheme
  • The AA. study the impacts of climate change on runoff and soil erosion in 2 Mediterranean watersheds, located in central and southern Portugal, by coupling a seasonal-scale with an event-scale model. PROMES results were used to estimate changes
  • plot as well as main outlet of the watershed associated with 12 storm events occurred during November 2006 to June 2007. The results verified that the accuracy of plot estimates on sediment and runoff improved while the plot length increased
