HMETS hydrological model

Source code and interface to lumped conceptual hydrological model HMETS

Code and interface to hydrological model HMETS. HMETS is a very simple, yet efficient, lumped conceptual hydrological model. It simulates all main hydrological processes including snow accumulation and snowmelt. Automatic calibration of the model is provided with the SCEUA and DDS algorithms (NOTE: to use DDS, additional files have to be downloaded - see below). There is a climate change module using the constant scaling downscaling method. A user guide is provided in the zip file. There are two main folders:
-HMETS code - use this folder if you want to use the m-files directly. A test watershed file is provided. Following the information in the user guide, you can run and calibrate the model within a few minutes.
-HMETS interface - use this folder if you want to use HMETS from its graphical user interface.
It has not been tested on older version of Matlab, but it is very likely to run properly on older versions.
IMPORTANT NOTES:
- To use the DDS algorithm (Tolson and Shoemaker, 2007) which is the most efficient optimization algorithm for HMETS, you have to download the p-files from the Github repository site. https://github.com/akamel001/Dynamic-Dimension-Search You do NOT have to download all of the files. Eight files are needed and are mentioned in the user guide.
- A few routines come from the air-sea exchange toolbox. All such files are mentioned in the user-guide and in the routines themselves http://www.mathworks.com/matlabcentral/linkexchange/links/1419-air-sea-toolbox-for-matlab. None of theses routines has been modified.
- the SCEUA algorithm has been lightly modified from the File exchange program code of Q. Duan. http://www.mathworks.com/matlabcentral/fileexchange/7671-shuffled-complex-evolution--sce-ua--method
