This paper demonstrates the effect of uncertainty in spatial estimates of rainfall on predictions of runoff volume, peak runoff and sediment yield. In particular, the effect of raingauge network density, spatial arrangement of individual raingauges within the catchment, and spatio-temporal characteristics of rainfall events on model predictions is examined. This is achieved by applying a distributed runoff-erosion model to a 6.73 km[2] catchment with a dense recording raingauge network in an area dominated by convective air-mass rainfall events and infiltration-excess overland flow mechanisms
