Supplementary Data for Spatially Explicit Water-Yield Dynamics and Hydrological Performance of the InVEST Annual Water Yield Model in Semi-Arid Catchments of Central South Africa

This dataset provides supplementary data supporting the study entitled “Spatially Explicit Water-Yield Dynamics and Hydrological Performance of the InVEST Annual Water Yield Model in Semi-Arid Catchments of Central South Africa.” It includes rainfall station metadata and quality-control summaries, monthly and annual observed streamflow volumes for gauging station C5H012, discharge data completeness assessments, annual rainy-day statistics used to derive the empirical Zhang parameter (Z = 7.17), annual residual analysis for model evaluation, and supplementary figures illustrating discharge data completeness and finite elasticity coefficients. These materials support the transparency, reproducibility, and interpretation of the InVEST Annual Water Yield model application in the C5H012 catchment.
