η = (f_p/K-1)*F_p/S_c
This formula uses 5 Variables

Variables Used

Porosity - Porosity is the ratio of volume of voids to volume of soil.
Infiltration Capacity at Any Time t - (Measured in Centimeter per Hour) - Infiltration Capacity at Any Time t from the start of the rainfall is the rate at which water percolates in the soil.
Darcy's Hydraulic Conductivity - (Measured in Centimeter per Hour) - Darcy's Hydraulic Conductivity measures soil's ability to transmit water, vital in understanding groundwater flow and environmental processes.
Cumulative Infiltration Capacity - (Measured in Centimeter per Hour) - Cumulative Infiltration Capacity is calculated by subtracting the cumulative runoff from the cumulative rainfall.
Capillary Suction at Wetting Front - Capillary Suction at Wetting Front is due to capillary attraction in the soil voids and is large for fine grained soils such as clays and small for sandy soils.

STEP 1: Convert Input(s) to Base Unit

Infiltration Capacity at Any Time t: 16 Centimeter per Hour --> 16 Centimeter per Hour No Conversion Required
Darcy's Hydraulic Conductivity: 13 Centimeter per Hour --> 13 Centimeter per Hour No Conversion Required

What is Green Ampt equation?

The Basic assumption behind the Green and Ampt equation is that water infiltrates into (relatively) dry soil as a sharp wetting front. The passage of this front causes the moisture content to increase from an initial value to a saturated value.

What is Infiltration Capacity?

The Infiltration Capacity is defined as the maximum rate of infiltration. It is most often measured in meters per day but can also be measured in other units of distance over time if necessary. The infiltration capacity decreases as the soil moisture content of soil surface layers increases.
