Formula Used

Maximum Potential Runoff = Total Precipitation-Initial Abstraction
R_max = P_T-I_a
This formula uses 3 Variables

Variables Used

Maximum Potential Runoff - (Measured in Cubic Meter) - Maximum Potential Runoff is generated when the movement of water into the soil is slow enough to result in water flow along the land surface and into water bodies.
Total Precipitation - (Measured in Cubic Meter) - Total Precipitation is the sum of rainfall and the assumed water equivalent of snowfall for a given year.
Initial Abstraction - (Measured in Cubic Meter) - Initial Abstraction is a parameter that accounts for all losses prior to runoff and consists mainly of interception, infiltration, evaporation, and surface depression storage.

Equation for Potential Maximum Retention

Go Potential Maximum Retention = Cumulative Infiltration*((Total Precipitation-Initial Abstraction)/Direct Surface Runoff)

Actual Infiltration

Go Cumulative Infiltration = Potential Maximum Retention*(Direct Surface Runoff/(Total Precipitation-Initial Abstraction))

Initial Abstraction given Ratio of Infiltration to Retention

Go Initial Abstraction = Total Precipitation-(Direct Surface Runoff*Potential Maximum Retention/Cumulative Infiltration)

Precipitation given Potential Maximum Retention

Go Total Precipitation = (Direct Surface Runoff*Potential Maximum Retention/Cumulative Infiltration)+Initial Abstraction

Cumulative Infiltration given Total Precipitation

Go Cumulative Infiltration = Total Precipitation-Initial Abstraction-Direct Surface Runoff

Direct Surface Runoff given Total Precipitation

Go Direct Surface Runoff = Total Precipitation-Initial Abstraction-Cumulative Infiltration

Water Balance Equation for Rainfall

Go Total Precipitation = Initial Abstraction+Cumulative Infiltration+Direct Surface Runoff

Initial Abstraction

Go Initial Abstraction = Total Precipitation-Cumulative Infiltration-Direct Surface Runoff

Initial Abstraction given Total Precipitation

Go Initial Abstraction = Total Precipitation-Maximum Potential Runoff

Precipitation given Maximum Potential Runoff

Go Total Precipitation = Maximum Potential Runoff+Initial Abstraction

Maximum Potential Runoff

Go Maximum Potential Runoff = Total Precipitation-Initial Abstraction

Maximum Potential Runoff Formula

Maximum Potential Runoff = Total Precipitation-Initial Abstraction
R_max = P_T-I_a

What is Water Balance Model?

Water Balance Model is a conceptual representation of the hydrologic cycle typically used to apply water balance principles at atmospheric, surface, soil water media, and subsurface scales.

What is Initial Abstraction?

Initial Abstraction is a parameter that accounts for all losses prior to runoff and consists mainly of interception, infiltration, evaporation, and surface depression storage.

How to Calculate Maximum Potential Runoff?
