This study used morphometric techniques to generate new information describing the evolu-
tion and hydrogeological behaviour of the Limpopo River Basin in Botswana, based on the
analysis of drainage surface features, form, and size. Drainage basins provide basic information
on their evolution, which, when quantified, yield information on the interaction between
tectonics, climatic, and surface processes. Drainage networks were extracted from the
Shuttle Radar Topographic Mission (SRTM) Digital Elevation Model (DEM) (90 m × 90 m), and
subsequently, morphometry indices were computed using ArcGIS 10.5. Drainage network
extraction was performed using the Arc Hydro extension in ArcGIS 10.5. ArcGIS 10.5 image
processing technique was used to extract lineaments and create rose diagrams. The results
showed that the Limpopo sub-basins in Botswana were drained by fourth- and fifth-order
streams, with a total drainage area of 107, 871 km2. Additionally, the basin asymmetry and
mean bifurcation ratios showed tilting in the sub-basins, suggesting tectonic instability and
structural control in a low – to-moderate active tectonic zone. The sub-basins also had a coarse
texture, indicating a high infiltration capacity. These results are essential for planning and
managing watershed systems, flood risk assessment, and potential groundwater assessment
for the different sub-basins of the Limpopo River Basin in Botswana.
