Spatial and temporal variability in floodplain sedimentation during individual hydrologic events on a lowland, meandering river: Allerton Park, Monticello, Illinois
Floodplains are major sinks and sources for sediment within the fluvial system and are constructed through two main processes: lateral and vertical accretion. In fine grained systems, vertical accretion dominates. Overbank flooding and floodplain inundation are dependent on bank height and local …

Late Quaternary fluvial stratigraphy of the St. Albans archeologic site (46KA27), West Virginia
… facies overlying a 7.8 m channel-sand facies. Sedimentation at the site began between 9,900 B.P. and 13,750 B.P. Floodplain sedimentation rates suggest a time closer to 9,900 B.P.</p>

Alluvial Sedimentation Associated with Logging in Low Gradient Watersheds in DeSoto National Forest, Mississippi
… properties, hillslope stability, and increase sedimentation rates in local streams and rivers. The aim of this research is to determine if forestry removal causes an increase of soil erosion and how it affects floodplain sedimentation in the low gradient watershed Whiskey Creek, located in …

Analysis of sediment dynamics in intensively managed landscapes
… contributions from cropland, grassland, forested floodplain, upper grazed floodplain, and lower grazed floodplain to the suspended sediment in the stream are evaluated by sediment fingerprinting techniques. The grazed areas of the floodplain are identified as the primary source of fine suspended …

Monitoring and measuring the impacts and environmental implications of flood events on contaminated sediment dispersal in the River Swale catchment, North Yorkshire
… the sediments of rivers and in their surrounding floodplains. This thesis investigates the mobilisation, transport and the overbank deposition of sediment-associated heavy metals during flood events on the River Swale, North Yorkshire. This catchment has a prolonged history of mining for lead and …

River-Floodplain Connectivity and Sediment Transport Potential: Applications to Sediment Dynamics on Floodplains and Juvenile Freshwater Mussel Settling in Rivers
River-floodplain connectivity is the degree of water-driven transport of matter, energy, and organisms between rivers and their floodplains. Recent advancement of high-resolution lidar data and numerical modeling is helpful to explore river-floodplain connectivity precisely to improve our …

Large-scale floodplain sediment dynamics in the Mekong Delta : present state and future prospects
… the intricate system of rivers, channels and floodplains and the scarcity of observations. Thus this thesis aimed at (1) the quantification of suspended sediment dynamics and associated sediment-nutrient deposition in floodplains of the MD, and (2) assessed the impacts of likely future …
