How to Evaluate Equation for Runoff?

Equation for Runoff evaluator uses Runoff Volume = Surface Runoff+Net Ground Water Flowing Outside Catchment to evaluate the Runoff Volume, The Equation for Runoff formula is defined as the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. Runoff Volume is denoted by QV symbol.
