%description
A Graphical user interface to calculate the rainfall-runoff relation using
the Natural Resources Conservation Service - Curve Number method (NRCS-CN
method) but include modifications by Hawkins et al., (2002) about the
Initial Abstraction. This GUI follows the programming logic of a
previously published software (Hernandez-Guzman et al.,
2011)<doi:10.1016/j.envsoft.2011.07.006>. It is a raster-based GIS tool
that outputs runoff estimates from Land use/land cover and hydrologic soil
group maps. This package has already been published in Journal of
Hydroinformatics (Hernandez-Guzman et al.,
2021)<doi:10.2166/hydro.2020.087> but it is under constant development at
the Institute about Natural Resources Research (INIRENA) from the
Universidad Michoacana de San Nicolas de Hidalgo and represents a
collaborative effort between the Hydro-Geomatic Lab (INIRENA) with the
Environmental Management Lab (CIAD, A.C.).
