HYMOD2 Hydrological Model Matlab Code

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.
