📦 About

pySWATPlus is an open-source Python package that provides a programmatic interface to the SWAT+ model, allowing users to run simulations and conduct custom experiments.

✨ Key Features

• Modify model parameters through the calibration.cal file.
• Run SWAT+ simulations seamlessly.
• Compute performance metrics using widely adopted indicators.
• Perform sensitivity analysis on model parameters using the SALib Python package, with support for parallel computation; currently, only Sobol sampling and Sobol indices are supported.
