River Discharge• Volume rate of water flow through a cross-

sectional area• Units of m3/s (cubic meters per second) or ft3/s

(cubic feet per second or cfs)

Sediment Yield

• Total sediment exported from a drainage basin to the continental margin

• Volume or weight of sediment per unit area of drainage basin
