SWAT streamflow calibration statistics and calibration parameter values for the HUC2-02 Mid-Atlantic Region

The dataverse encompasses comprehensive data on streamflow calibration parameters at the HUC12 scale across the United States. This dataset is derived from two calibration studies: 1) Calibration of the SWAT model for gaged watersheds (Bawa et al., 2023, Journal of Hydrology) and 2) Regionalization of Calibration Parameters using Machine Learning and Physical Similarity to extend calibration parameters from gaged to ungagged HUC12 subbasins (Bawa et al., 2023, Water Resource Research).

The dataset includes information specifically on the HUC12 scale streamflow calibration of the HUC2-02 Mid-Atlantic Region. Table A1 presents calibration statistics before and after machine learning-based regionalization of calibration parameters and Table 2 provides calibration parameter values for all 3,036 HUC12 subbasins within the HUC2-02 region.
