FAQ

What is Precipitation?
The Precipitation formula is defined as the sum of Surface Runoff and Evaporation over a specified catchment area and is represented as P=S+E or Precipitation=Surface Runoff+Evaporation from water body (mm/day) . Surface Runoff water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle. 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 Precipitation?
