Conceptual hydrogeological cross-section across the Gaborone catchment from Kanye area to Gaborone city, Botswana

The dataset contains a scaled, semi-quantitative conceptual hydrogeological model of the Gaborone catchment along a general WSW-ENE direction including; (1) the geographic coordinates of the extremities of each segment of the polyline transect; (2) the raster, scaled image of the conceptual hydrogeological cross-section.

Where/When

Study area

Provenance & quality

The conceptual hydrogeological cross-section was generated from publicly available, primary datasets, including geological maps, hydrogeological maps, and hydrological datasets, using the following workflow:
• With Google Earth: (1) polyline transect selection; (2) extraction of the geographic coordinates of the extremities of each segment of the polyline transect; (3) topography extraction along the full polyline transect;
• With both Google Earth and Inkscape: (4) delineation of geological unit boundaries and regional faults at the surface; (5) extension of geological units and faults at depth; (6) location of surface water bodies; i.e. streams, reservoirs and dams; (7) projection of monitoring boreholes and delineation of water table;
• With Inkscape: (8) water table interpolation across the cross-section; (9) interpretation and drawing of groundwater flow directions; (10) interpretation drawing of surface run-off, groundwater recharge, and groundwater-surface water interaction processes; and (11) raster image export at 600 dpi.
