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.

BASINS, HSPF, and various utilities are available at https://github.com/respec/BASINS/releases

For HSPF I also have developed:

• hspfbintoolbox to extract data from the HSPF binary output file https://timcera.bitbucket.io/hspfbintoolbox/docs/index.html
• hspf_utils to create water balance tables of the entire model, or particular years, and to create a CSV file useful to join to a GIS layer to map model results. https://timcera.bitbucket.io/hspf_utils/docs/index.html

pip install wdmtoolbox

conda install -c conda-forge wdmtoolbox

To compile from source you need a "C" compiler (gcc on Linux, Visual Studio 2019 for Windows), a FORTRAN compiler (gfortran on Linux, MSYS2/MINGW gfortran on Windows), Python 3.7, 3.8, or 3.9 with "numpy" installed to be able to access f2py.
