Datasets and Code for "Controls on Groundwater Recharge at the Watershed Scale: Nonlinear Response and Driving Factors across 210 Contiguous U.S. Basins"

These datasets support the paper "Controls on Groundwater Recharge at the Watershed Scale: Nonlinear Response and Driving Factors across 210 Contiguous U.S. Basins". The datasets include: ds01. Daily streamflow and electrical conductivity (EC) data for the 210 gages used in this study. ds02. Hydrograph separation results for the 210 gages obtained using the improved EC mass balance method. ds03. Python code implementing the hydrograph separation method. ds04. Linear and nonlinear response distributions of streamflow and recharge derived from ERRA for each gage. ds05. Watershed attributes (35 variables), separation parameters (17 variables), and ERRA outputs for the 210 watersheds.
