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 …

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 …

Comparison of Hydraulic Function and Channel-Floodplain Connectivity Between Actively and Passively Restored Reaches of Stroubles Creek 11 Years After Restoration
… while Treatment 3 was designed with a flat inset floodplain cut into the banks. The model results showed that the self-adjustment in Treatment 1 exhibited inset floodplains with diverse topographical structure including floodplain channels. These adjustments provided higher floodplain volume and …

Floodplain Hydrology and Biogeochemistry
River-floodplain connectivity is defined as the water mediated transfer of materials and energy between a river or stream and its adjacent floodplain. It is generally accepted that restoring and/or enhancing river-floodplain connectivity can reduce the downstream flux of reactive solutes such as …

Monitoring and Managing River Corridors in the Midst of Growing Water Demand
… between river channels and their adjacent floodplains. The importance of this hydrologic connectivity between rivers and floodplains has been emphasized in recent decades and now ecological engineering techniques such as stream restoration are often utilized to restore connectivity between …

Evaluating Floodplain Hydrologic Connectivity, Yakima River, WA
… to increase the quality and quantity of aquatic floodplain habitat, and evaluating the effectiveness of reconnection is a crucial and often neglected part of these projects. The purpose of this research was to collect baseline data to determine if and how floodplain connectivity affects water …

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 …

Riparian resilience in the face of interacting disturbances: understanding complex interactions between wildfire, erosion, and beaver (Castor canadensis) in grazed dryland riparian systems of low order streams in North Central Washington State, USA
… transport and pH, increased stream channel and floodplain connectivity, increased vegetation diversity in floodplain landforms, and reduced non-native species in burned riparian systems with beaver, which suggest that beaver can effectively increase wildfire resilience in streams. By studying …

Landscape vulnerability to flood impacts in a human-dominated floodplain
The variable flood regime of a natural floodplain supports a variety of vegetation and habitat niches and regenerates the landscape through erosion and deposition. However, flooding of human-dominated landscapes are termed ``natural disasters'' due to potential devastating impacts such as the loss …

Determining primary drivers of river bead functionality in mountain headwater streams
… assessment efforts, restoration of channel-floodplain connectivity and facilitating greater retention of water will provide the biggest return on river restoration investment by increasing the width of the active floodplain. Researching drivers of functionality also provides a crucial link …

Ecological-Hydrological Feedback in Forested Wetlands
… tree water use and growth responses to river-floodplain connectivity and water level variability, and interactions between tree-level and site-level effects of flooding. Energy-balance measurements in the understory of a permanently flooded swamp showed nearly all energy was partitioned to …

Factors affecting the dispersal of coarse fish
… and ecology of wild and stocked cyprinids in floodplain rivers, especially under the influence of elevated flows. This study examined the factors affecting the lateral and longitudinal dispersal of juvenile and adult (wild and stocked) coarse fish in three lowland river catchments, namely the …
