Examining the morphodynamics of point bars
Kory Konsoer, Assistant Professor of Geography and CSI Fellow, has been at LSU since 2014. He and his research group study the morphodynamics of meandering rivers through process-based field investigations focusing on hydrodynamics, sediment transport, and planform evolution of rivers across the US. One of the group’s current research projects aims to improve our understanding of the dynamic interactions between channel migration (rate and pattern of erosion) and point bar development (internal structure and sedimentology) on meandering rivers with complex planform geometry. This research is being conducted in collaboration with scientists from the USDA – National Sedimentation Laboratory in Oxford, MS. The study employs a range of techniques to provide high-resolution morphologic, geologic, and hydrodynamic data, including terrestrial LiDAR, sUAS (drones), multibeam echo sounding (MBES), ground penetrating radar (GPR), and acoustic Doppler current profilers (ADCP), on a series of meander bends along the Pearl River (Louisiana) and the Wabash River (Illinois). Findings from this project have implications for determining how sediment routing paths lead to floodplain alluvial architecture, and sediment flux to downstream reaches including coastal margins.
