Initial Abstraction given Total Precipitation Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Total Precipitation - (Measured in Cubic Meter) - Total Precipitation is the sum of rainfall and the assumed water equivalent of snowfall for a given year.
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.

STEP 1: Convert Input(s) to Base Unit

Total Precipitation: 16 Cubic Meter --> 16 Cubic Meter No Conversion Required
Maximum Potential Runoff: 11 Cubic Meter --> 11 Cubic Meter No Conversion Required

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

Initial Abstraction given Total Precipitation Formula

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