Clarence River lowland floodplain : a morphostratigraphic analysis of a complex Holocene floodplain
… about 2,500 years B.P. But unlike typical floodplains of the laterally stable channels, the Clarence floodplain is complex, having subsidiary channel-splay complexes nested within the broader floodplain, which cover about 40% by area of the Clarence floodplain. Geomorphic elements within …

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 …

From grain to floodplain: evaluating heterogeneity of floodplain hydrostratigraphy using sedimentology, geophysics, and remote sensing
Floodplain stratigraphy, a major structural element of alluvial aquifers, is a fundamental component of floodplain heterogeneity, hydraulic conductivity, and connectivity. Watershed-scale hydrological models often simplify floodplains by modeling them as largely homogeneous, which inherently …

Microbial transformation of arsenic in Bengal floodplain
Presence of arsenic in paddy soils in Bangladesh has become a major concern, with Holocene soils reported to have higher levels of arsenic compared to Pleistocene. However, to date there is limited data on how geomorphology, land use and soil microbes drive bioavailability of arsenic in the paddy …

Energy Flow in a Floodplain Aquifer Ecosystem
… for the invertebrate community of a large 20 km2 floodplain aquifer, based on biomass distributions, organismal respirometry, in situ community respiration, mesocosm and microcosm experiments, stable isotopes and invertebrate gut contents. The invertebrate respiration scaling exponent was 0.474 …

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 …

Floodplain and Flood Probability Mapping Using Geodatabases
… presents methods of creating digital maps for floodplain delineation and flood probability studies and storing them in a geodatabase. Methods for creating a geodatabase for water resources outside of a GIS are presented. The geodatabase follows the ArcHydro data model. Methods are also shown …

Implications of floodplain dynamics for reservoir operation
… for feedbacks between reservoir operation and floodplain development, a specific case of socio-economic feedbacks, and discuss its potential implications for reservoir management.

Dynamics of two South African floodplain forests
Riverine systems are an important component of landscape diversity because of the interaction of biodiversity patterns, disturbance regimes and environmental gradients therein. They stabilise migrating river channels and ameliorate hydrological extremes. Concern is growing over the degradation of …

Constructed Floodplain Wetland Effectiveness for Stormwater Management
A 0.2-hectare wetland was constructed in the floodplain of Opequon Creek in Northern Virginia as a best management practice (BMP) for stormwater management. The research goals were to 1) determine if wetland hydrology existed and quantify the role of groundwater exchange in the constructed wetland …

Watershed Scale Impacts of Floodplain Restoration on Nitrate Removal and the Practical Applications of Modeling Cumulative Floodplain Restoration Hydraulics
… as nutrient processing and flood attenuation. Floodplain restoration increases floodplain exchange and is commonly implemented to improve water quality and reduce flood impacts at watershed scales. However, the effect of multiple restoration projects at the watershed scale is not well studied. …

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 …

Critical Review of Inundation Mapping Procedures for Floodplain Management
Inundation mapping is a major component of floodplain management, providing critical information as to the consequences of potential failures of flood control structures, such as dams. To develop inundation maps, a dam and river system are modeled with engineering computer programs, and a …

South Chattanooga and Chattanooga Creek floodplain: A case study
… opportunities and would run through the floodplain along the entire length of the Chattanooga Creek Superfund site. Due to persistent flooding of Chattanooga Creek and lingering questions about the adequacy of past and proposed removal actions, South Chattanooga citizens were not …

Model Development and Incorporation of GIS Tools for Floodplain Management
Floodplain management consists of efforts to reduce flood damage to critical infrastructure and to protect the life and health of individuals from flooding. A major component of this effort is the monitoring of flood control structures such as dams because the potential failure of these structures …

Organic carbon dynamics of the Neches River and its floodplain.
… of its biomass from production within the floodplain. The Neches River in the Big Thicket National Preserve is a large blackwater river that has an extensive forested floodplain. Organic carbon was analyzed within the floodplain waters and the river (upstream and downstream of the …
