Precipitation given Potential Maximum Retention Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Precipitation = (Direct Surface Runoff*Potential Maximum Retention/Cumulative Infiltration)+Initial Abstraction
P_T = (Q*S/F)+I_a
This formula uses 5 Variables

Variables Used

Total Precipitation - (Measured in Cubic Meter) - Total Precipitation is the sum of rainfall and the assumed water equivalent of snowfall for a given year.
Direct Surface Runoff - (Measured in Cubic Meter) - Direct Surface Runoff is the rain or meltwater that runs off during the rain or melt event as overland flow or in the vegetation cover above frozen soil.
Potential Maximum Retention - (Measured in Cubic Meter) - The potential maximum retention mainly represents infiltration occurring after runoff has started.
Cumulative Infiltration - (Measured in Cubic Meter) - The cumulative infiltration excluding initial abstraction is total amount of water that soil strata are able to absorb from rainfall or irrigation in a given time.
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.

STEP 1: Convert Input(s) to Base Unit

Direct Surface Runoff: 9 Cubic Meter --> 9 Cubic Meter No Conversion Required
Potential Maximum Retention: 2.5 Cubic Meter --> 2.5 Cubic Meter No Conversion Required
Cumulative Infiltration: 2 Cubic Meter --> 2 Cubic Meter No Conversion Required
Initial Abstraction: 5 Cubic Meter --> 5 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_T = (Q*S/F)+I_a --> (9*2.5/2)+5

Evaluating ... ...

P_T = 16.25

STEP 3: Convert Result to Output's Unit

16.25 Cubic Meter --> No Conversion Required

FINAL ANSWER

16.25 Cubic Meter <-- Total Precipitation
