Zusammenfassung |
This research reconstructs the past evolution of the Limpopo River, a
transboundary system located in south-eastern Africa, and describes its
geomorphological settings through a literature review and field work
activities, with the aim of analysing flood hazard in the basin. Major
changes have occurred since the late Jurassic–early Cretaceous period due to
successive tectonic events. The paper demonstrates that the apparently
abandoned drainage conformation of the palaeo-Limpopo in the upper and middle
stretches of the river today constitutes preferential flood-prone areas in
the case of major rainfall events. An important palaeo-delta is identified in
the lower Limpopo, which imposes a particular drainage pattern onto the
floodplain in Mozambique and influences the flood dynamics at present. The
adopted method is helpful in determining flood hazard in a data-scarce area
showing complex fluvial dynamics, and allows for the identification of
unsuitable locations for human settlements. |
