DESCRIPTION

The program is written in fortran 90 and compiled with Fortran intel 2018 (note that incompatibilities with gfortran or gf95 might exist). It calculates soil infiltration and redistribution during a series of storms for 1D (vertical) and 3D (point source, drip/trickle) using Munoz-Carpena and Gowdish (2009, 2018) MGAR method
Fortran source code, windows executables and sample files are included in the package.
To run type  "mgar 1" or mgar 3" from the command line. Other values different that 1 or 3 will result in an error.

SAMPLE FILES 
A brief PDF with details of the content of the files is included in package. See also journal papers below for additional details.

a) 1D case 
Soil_In.txt 'Input file, Soil MGAR1D parameters
Rain_In.txt 'Input file, Rainfall time series for 1D case
1DInfilOutput.txt 'Output file from 1D case 
Other files not used (deprecated). They will be cleaned up in a future release

b) 2D case
Soil_In3D.txt 'Input file, Soil MGAR3D parameters and multistory rainfall pattern. Units: Length [cm], Timestep [h]
3DInfilOutput.txt 'Output file from 1D case for the 90 degree line (vertical below point source) inside the wet bulb
Other files not used (deprecated). They will be cleaned up in a future release
