Controls on Suspended Sediment Concentration-Disch
arge 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
