HYMOD2 is an improved version of the widely used hydrologic model HYMOD. The improvements are made based on simple but realistic evaporation process multi-parameterization. There are two files in this resource, (1) hymod.m and (2) Inputs.mat. The first file is the model code which is well commented so that it is easy to follow. The second file is an example input file which consists of time series of three different variables, precipitation (column-1), potential evapotranspiration (column-2) and discharge (column-3), all in mm.
