Abstract

This paper discusses the results of 2 detailed field surveys, carried out after extreme rainfall events in springtime. The objectives are 1) to investigate to what extent the sediment delivery ratio of a catchment scale is controlled by the spatial organisation of land use in the absence of spatial control measures, and 2) to compare the size characteristics of the deposited sediment with the size characteristics of the source soil material. Such information may be used to optimise the spatial distribution of land-use in order to reduce sediment and pollutant delivery to streams
