Were Rivers Flowing across the Sahara During the Last Interglacial? Implications for Human Migration through Africa
Figure 3
Seasonal flow of surface water across the Sahara during the last interglacial.
Monthly probability of surface water being present for (a) August, (b) September, (c) October and (d) November. These illustrate the hydrodynamics of the system simulated by the large scale 2d hydraulic model that routes a flood wave of water north across the desert from the mountains.
