Actual Infiltration Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Potential Maximum Retention - (Measured in Cubic Meter) - The potential maximum retention mainly represents infiltration occurring after runoff has started.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Potential Maximum Retention: 2.5 Cubic Meter --> 2.5 Cubic Meter No Conversion Required
Direct Surface Runoff: 9 Cubic Meter --> 9 Cubic Meter No Conversion Required
Total Precipitation: 16 Cubic Meter --> 16 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

F = S*(Q/(P_T-I_a)) --> 2.5*(9/(16-5))

Evaluating ... ...

F = 2.04545454545455

STEP 3: Convert Result to Output's Unit

2.04545454545455 Cubic Meter --> No Conversion Required

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 Actual Infiltration?

Actual Infiltration calculator uses Cumulative Infiltration = Potential Maximum Retention*(Direct Surface Runoff/(Total Precipitation-Initial Abstraction)) to calculate the Cumulative Infiltration, The Actual Infiltration formula is defined as the process of water entry into the soil through the earth's surface. The water at the soil surface can originate from rain, snowmelt or anthropogenic activities. Cumulative Infiltration is denoted by F symbol.
