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.
