Read and write Watershed Data Management (WDM) files

The wdmtoolbox

The wdmtoolbox is a Python script and library to read/write/manage Watershed Data Management (WDM) files used for time-series in hydrology and hydrological simulation. WDM files are used in the Hydrological Simulation Program - FORTRAN (HSPF) and the Better Assessment of Science Integrating point and Non-point Sources (BASINS). HSPF is a part of the BASINS system.

If these requirements are not locally available, ‘pip’ or ‘easy_install’ will attempt to download and install.

If you use the source distribution you have to have a FORTRAN compiler installed and configured for your environment.


On Windows should be as easy as running pip install wdmtoolbox in a command shell window. For Windows, the support platforms are Python 2.7 and 3.4. Not sure on Windows whether this will bring in pandas but as mentioned above, if you start with Conda, Enthought, or Python(x,y) then you won’t have a problem.

On Linux (and maybe even Mac OSX?) you could use pip install wdmtoolbox at any terminal that has access to gfortran and of course your Python interpreter.
