dc.description.abstractSediment transport in rivers plays multiple key roles within every watershed. Fine sediments transported by rivers carry with them vital nutrients that are essential to riverine and estuarine life, when not in excess. Floodplain storage of these same fine sediments is of interest to parties attempting to mitigate downstream sediment and nutrient pollution. However, historic methodological and technological limitations have limited fine-scale studies of floodplain storage. This exploratory study, utilizing modern multi-temporal high-resolution topography and advanced geospatial analysis tools, sought to overcome these limitations and comprehensively assess floodplain sediment dynamics and the conditions governing them. Our findings suggest that in addition to geometric measures, flow conditions across a floodplain during the falling limb are strong predictors of floodplain-scale sedimentology. Further results suggest modern high-resolution topography is capable of adequately modeling fine-scale sediment dynamics from single storms, accurately characterizing low-relief landforms, and providing detailed terrains for hydraulic models.
