Stratigraphically and geomorphically complex, fluvial systems can be impacted by both bankfull and overbank stages. In this paper, Ghinassiet al. explore 3D geometries of sandy deposits accumulated by a fluvial pointbar in the Pleistocene of the Dandiero Basin (Eritrea), reconstructing the main bar geometry and discuss its morphodynamic evolution and investigating the role of overbank flow in channel bend dynamics. The results of this work provide new conceptual depositional models to explain fluvial pointbar dynamics, and are of interest in terms of fluvial environment management and exploration of alluvial sandstone bodies.
