Introduction to River Systems
• Velocity and discharge• Length and gradient• Channel and floodplain development• Drainage area• Sediment yield
River Velocity
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)

Channel and Floodplain Development
Drainage Area
Sediment Yield
• Total sediment exported from a drainage basin to the continental margin
• Volume or weight of sediment per unit area of drainage basin
