Controls on Suspended Sediment Concentration-Discharge Relationships • Intensity and areal distribution of precipitation event; • The amount and rate of runoff; • Distance of the sampling site from sources of water and sediment production (upland areas); • Differences in the transport rates between water and sediment; • The amount of sediment stored within and along the channel; and • The depletion of easily eroded debris within the channel or the surrounding uplands
