Geoarchaeology of the Orontes River Floodplain Surrounding Tell Qarqur, Syria
… northern Ghab Basin, located within the Orontes River Valley of western Syria. Tell Qarqur, the archaeological site around which this project is focused, has a continuous occupational sequence throughout the Holocene. Annual inundation of the site by seasonal marshlands suggests that the marsh …

Ecology of spring-migrating waterfowl within the lower Wabash River floodplain
… for many waterfowl species. The lower Wabash River floodplain, in southeastern Illinois and southwestern Indiana, has been anecdotally suggested to contain suitable habitat for large concentrations of migratory waterfowl, but currently lacks robust estimates of waterfowl use. Therefore, I …

Flood Processes, Forest Dynamics, and Disturbance In the Congaree River Floodplain, South Carolina
… a result of the biophysical linkages between the river and the floodplain. These ecosystems contain significant habitat heterogeneity and support rich diversity of species, but have been altered and manipulated by anthropogenic impacts. This study was designed to examine the forest development …

The Role of Floods in Particulate Organic Matter Dynamics of a Southern Appalachian River/Floodplain Ecosystem
… matter (POM) dynamics of the Little Tennessee river/floodplain ecosystem in western North Carolina, USA. I measured litter inputs, leaf breakdown, floodplain litter, and aboveground herbaceous net primary production at 12 sites. Annual litter inputs (274-625 g m-2 y-1) were typical of a …

Mixed-Silver Maple Forests Of The Upper Mississippi River Floodplain: Variations In Composition, Structure, And Growth Along Environmental Gradients
Floodplain forests of the Upper Mississippi River are characterized by complex interactions between biota and the physical environment, specifically aspects of hydrology. The role of environmental variation in overstory composition, structure, and growth is not well documented. Goals of this study …

Sapling growth and recruitment as affected by flooding and canopy gap formation in a river floodplain forest in southeast Texas
… flooding history using a combination of river gauging, a local water-level recorder, and contour maps. 1979 was an extreme flood year for this site, as was 1989. Reduction in flooding frequency since dam construction in 1965 was significant for all elevations, while reduction in flooding …

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 …

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 …

PATTERNS OF SEEDFALL AND SEEDLING ESTABLISHMENT IN AN EAST TEXAS RIVER FLOODPLAIN FOREST: THE CONTRIBUTION OF SEEDLING DYNAMICS TO SPECIES COEXISTENCE (PLANT DEMOGRAPHY, DISPERSAL, TREE REGENERATION, SURVIVORSHIP, MORTALITY)
… survivorship, and growth in an East Texas river floodplain forest from 1980 through 1984, and estimated the importance of several factors including flooding, drought, shading, insect herbivory, and fungal attack in causing seedling mortality. Tree species fell into two groups on the basis …

Temporal Patterns of Aquatic Macroinvertebrate Communities and Organic Matter Standing Stock Availability in a Coastal Floodplain (Altamaha River, Georgia)
<p>River floodplain habitats of the Southeastern United States are sites of high biological productivity that rely on a predictable flooding event as a keystone process. This study took place in a river-floodplain area of the Altamaha River, an unimpounded large-order river in the Coastal Plains …

Flood pulse influences on exploited fish populations of the Central Amazon
… population dynamics and catches of fishes from river-floodplains. Although different measures of flood pulses, here called flood pulse variables, have been correlated to changes in catches of river-floodplain fishes, the flood pulse variables that have the strongest relationships to catches have …

Applied geology of the Bismarck-Mandan area, North Dakota
… miles located along both sides of' the Missouri River in south-central North Dakota. The area can be divided into two major physiographic divisions: the broad Missouri River floodplain and the nearly flat uplands which are dissected by minor streams. Geologic units in the area include Upper …

Wildlife Habitat in the James River Valley, South Dakota
… on the 12 485 ha study area of the James River floodplain in north-eastern South Dakota. Included were vegetation mapping, small mammal trapping, waterfowl breeding pair counts, waterfowl brood counts, bird census routes, and general observations. Natural vegetation consisted of 3181 ha of …

Quarternary Alluvial Deposition in the Upper Green River Valley, Kentucky
… geomorphic evolution of the Upper Green River in Kentucky by documenting the nature of flood plain sediments at two sites along the valley bottom of the Upper Green River between Mammoth Cave National Park and Green River Lake. Field methods employed included stratigraphic descriptions of …

Surface geology for land use planning, Minot, North Dakota area
… square kilometres along both sides of the Souris River in north-central North Dakota. The area can be divided into the flat Souris River floodplain, the steeply sloping sides of the Souris and Des Lacs meltwater channels and larger tributaries, and the gently undulating uplands dissected by small …

Air-breathing and movement ecology of Arapaima sp. in the Amazon
The annual hydrological cycle of floodplains supports fishes that are uniquely adapted to optimize resources throughout the year. Such adaptations to changing environments include air-breathing for seasonally hypoxic waters and directed movements to best utilize habitats as they become available. …
