SoilStorage: Calculating S in the Curve Number Equation from soil water content

Description

This function calculates S, used in the SCS-CN equation, from the water content of the soil.

Usage

SoilStorage(S_avg, field_capacity, soil_water_content, porosity)

Arguments

S_avg

Average S, as used normally in the CN equation, calculated from the curve number, which is based on land-use. This is in units of depth, often mm or inches

field_capacity

field capacity - the amount of water that a soil can hold after drainage. (fraction)

soil_water_content

Soil water content (fraction) on a given day.

porosity

Saturated water content, approximately equal to the porosity of a soil (fraction)
