• Model:TopoFlow-Infiltration-Green-Ampt  + (The input variables used by the simple Gre … The input variables used by the simple Green-Ampt method for modeling infiltration are defined as follows:</br> K_s = saturated hydraulic conductivity (m / s)</br> K_i = initial hydraulic conductivity (m / s) (typically much less than Ks)</br> θ_s = soil water content at ψ=0 (unitless) (typically set to the porosity, φ)</br> θ_i = initial soil water content (unitless)</br> G = capillary length scale (meters) </br> = integral over all ψ of K(ψ) / K_s</br> = (almost always between ψ_B and 2*ψ_B)</br> P = precipitation rate (mm / sec)</br> M = snowmelt rate (mm / sec)</br></br>The behavior of this component is controlled with a configuration (CFG) file, which may point to other files that contain input data.
