  • Updated description of SCS Hydrological Soil Groups Over South Africa At Terrain Unit Resolution from

    Auto-imported dataset for scs-hydrological-soil-groups-over-south-africa-at-terrain-unit-resolution
    to
    This dataset provides a high‑resolution, terrain‑unit‑based map of SCS (Soil Conservation Service) runoff‑related hydrological soil groups for South Africa. Developed to support the widespread use of the SCS hydrograph‑generating technique in the country, the dataset assigns SCS hydrological soil groups to each of South Africa’s 27 491 terrain units. The classification is derived by linking SCS soil groups to South African soil series, incorporating key soil texture, drainage, and hydraulic characteristics required for runoff modelling. The dataset includes a detailed, nationally consistent methodology for defining and mapping hydrological soil groups, along with the resulting spatial layer. Compared with earlier maps based on coarser soil‑land‑type units, this terrain‑unit approach provides significantly enhanced spatial detail, improving the representation of runoff generation processes across catchments nationwide. The final map offers refined input data for hydrological modelling, design flood estimation, and water‑resources applications.
