ABSTRACT:
HYMOD2 is an improved version of the widely used hydrological model HYMOD. The improvements are made based on simple but realistic evaporation process parameterizations. The file "hymod2.m" is the model code, which is also well commented so that it is easy to follow.
The input file needs to be in MATLAB data format (.mat). Rows should include daily sequence and columns are for the following variables: Precipitation (column-1), Potential Evaporation (column-2) and Discharge (column-3). Check "LoadData.m" function for input information and make changes as necessary. Parameter values are assigned in "PriorHyModV2.m" function. Results are stored in "Results.mat" file.
Disclaimer:
This program comes "as is" and the authors cannot be held responsible for any issues resulting from the improper functioning of the program. If found, please report the bugs to royt@email.arizona.edu. Prompt action will be taken to fix reported bugs.

ABSTRACT:
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.
