Explore floodplain sedimentation patterns above the deltaic apex of the Lower Mississippi River near Natchez, USA, through this 52-minute conference talk. Examine how a prolific series of floods over the past 15 years has resulted in overbank sedimentation within the embanked floodplain system. Analyze overbank sediment samples collected following flood events and investigate floodplain sediment cores to understand how depositional thicknesses, sedimentation rates, grain size distributions, organic carbon content, and nutrient concentrations vary based on multiple factors. Discover the relationships between sub-basin inputs, flood magnitude and duration, and long-term historical trends associated with land-use changes and flood mitigation efforts. Gain insights into the complex dynamics of river-floodplain interactions and their implications for sediment transport and deposition in one of North America's most significant river systems.
