FAQ

What is Runoff when Precipitation is known.?
The Runoff when Precipitation is known. formula is defined the excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds and is represented as S=P-E or Surface Runoff=Precipitation-Evaporation from water body (mm/day) . Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations. and Evaporation from water body (mm/day) is the process by which liquid water from an open water surface is converted directly to water vapor.
How to calculate Runoff when Precipitation is known.?
The Runoff when Precipitation is known. formula is defined the excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds is calculated using Surface Runoff=Precipitation-Evaporation from water body (mm/day) . To calculate Runoff when Precipitation is known., you need Precipitation (P) and Evaporation from water body (mm/day) (E).
