SoilStorage {EcoHydRology} | R Documentation |
This function calculates S, used in the SCS-CN equation, from the water content of the soil.
SoilStorage(S_avg, field_capacity, soil_water_content, porosity)
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) |
This equation is not the same as the one used in SWAT. It was given to Dr. Todd Walter by Dr. Keith E. Saxton
