hydroSWAT: Tools for multi-objective calibration and workflows for the SWAT model in R

`hydroSWAT` is an open-source R package for multi-objective calibration of theSoil and Water Assessment Tool (SWAT). It implements the Non-dominated SortingGenetic Algorithm II (NSGA-II) with parallel execution capabilities, enablingefficient evaluation of large populations of parameter sets. The packagesupports calibration for both the standard SWAT model and its tropical variant(SWAT-T). Beyond calibration, `hydroSWAT` provides tools for preparing forcing data,running simulations, evaluating model performance, and conductingpost-calibration analysis within a unified R-based workflow. A built-in dataset and a vignette implementing a complete calibration andresults analysis workflow are included to support reproducibility and useradoption.
