Runoff may be defined as that part of precipitation as well as any other flow contributions which appear in surface streams of either perennial or seasonal nature.. It is the flow collected from a drainage basin appearing at the outlet of the basin or catchment. Runoff. Streamflow. Generation. Excess Rainfall and Direct Runoff. SCS Method for runoff amount.
