Modeled vadose-zone water fluxes from spin-up sensitivity experiments with representative soil profiles in the Modesto–Turlock area, California's Central Valley

This dataset provides processed simulation outputs for evaluating spin-up effects in thick vadose zones, including realization-level and scenario-level water flux results across different spin-up strategies, soil profiles, initial states, groundwater-table depths, and evaluation depths. These simulation data support a manuscript submitted to Water Resources Research.
