Description

Calculates Green-Ampt infiltration for a given rainfall timeseries Reference: WinGampt by Parson & Carpena (2009): Based largely on this fortran program. http://abe.ufl.edu/carpena/software/wingampt.shtml

Usage

gampt.infil(Time, rainfall, soil.para, smax = 0.5, tstep, tol = 1e-06, ...)

Arguments

Time	Time input
rainfall	Rainfall vector corresponding to Time input
soil.para	Soil hydraulic parameters: saturated water content(ths), initial water content(thi), Ksat, Sav
smax	Maximum storage at the surface
tol	Maximum tolerance for the absolute error in iterative solution of Chu's equation

Examples

infil = gampt.infil(Time = seq(0, 4, 0.1),
rainfall = c(0, rep(1.5, 10), rep(0.1, 10), rep(1.0, 20)),
soil.para = list(ths = 0.499, thi = 0.25, Ksat = 0.044, Sav = 22.4),
smax = 0.8, tstep = 0.1, tol = 0.000001)
