Cumulative Impacts of Stream Restoration on Watershed-Scale Flood Attenuation, Floodplain Inundation, and Nitrate Removal
… gap by evaluating the impacts of different floodplain restoration practices, varied by location and length, on flood attenuation and floodplain inundation dynamics at the watershed scale during more frequent storm recurrence intervals (i.e., 2-year, 1-year, 0.5-year, and monthly). We created …

Basin-scale spatiotemporal analysis of hydrologic floodplain connectivity
Floodplain inundation often provides water quality benefits by trapping sediment and biogeochemically transforming other pollutants. Hydrologic floodplain connectivity is a measure of water exchanges and interactions between the main channel and the floodplain via surface (inundation) and …

Evaluating surface water–groundwater interactions in floodplains using SWAT+ and gwflow
Floodplains are essential ecosystems that provide a variety of economic, hydrologic, and ecologic services. Within floodplains, surface water-groundwater exchange plays an important role in facilitating biogeochemical processing and can have a strong influence on hydrology through infiltration or …

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 …

Objectively identifying spatial variability in bankfull stage
… that defines the transition between channel and floodplain and marks the level of incipient flooding, bankfull flow represents an important geomorphic and hydrological threshold. However, most field methods of bankfull identification rely on subjective judgement which can result in varying …

The hydraulic and hydrological performance of large wood accumulation in a low-order forest stream
… the functioning of forested river channels and floodplains. Large wood has previously been removed from rivers in order to reduce flow resistance and increase channel conveyance. However, recently there has been an appreciation of the role of large wood accumulations in creating important …

Impacts of inundation and season on greenhouse gas fluxes from a low-order floodplain
… decreased emissions may mitigate its impacts. Floodplains may be particularly susceptible to climate change, as their biogeochemical processing is driven by hydrology. For this study, ten mesocosms were installed on the floodplain of Stroubles Creek in southwest Virginia. A flood event was …

The Influence of Livestock Watering Ponds (Dugouts) on Native Stream Fishes, Especially the Endangered Topeka Shiner (Notropis topeka)
Natural depressional wetlands in the floodplain are part of the mosaic of aquatic habitats important to stream fishes. Livestock watering holes (i.e., dugouts) are constructed in floodplains, yet the influence of these manmade wetlands on native stream fishes is unknown. Such information is …

The role of soil moisture and weather patterns for flood occurrence and characteristics at the river basin scale
… runoff generation, flood routing, possible floodplain inundation and finally flood losses. In this thesis, a comprehensive probabilistic process-based understanding of the causes and effects of floods is advanced. The spatial and temporal dynamics of flood events as well as the geophysical …

A novel approach for large-scale flood risk assessments
… river network model, a 2D raster based inundation model and the flood loss model FELMOps+r. Subsequently, the model chain was applied to the Elbe catchment, one of the largest catchments in Germany. For the proof-of-concept, a continuous simulation was per-formed for the period of …
