Floodplain deposits, also known as Riverine Deposits, were formed by the deposition of river sediments during floods in flood basins (backswamp deposits) or on levees along the river banks (levee deposits).

In a little while, we turned into a different habitat called a "backswamp." Carefully he guided the boat through an eerie forest of half-submerged trees.

The types of aquatic habitats and vegetation sampled were river, "corixo" (anabranch, oxbow), floating meadow, lake, pond, seasonal channel ("vazante"), backswamp and incoming stream.

The transect is about 1 kilometer and ran from the alluvial inundated plain (Backswamp) to the upper slope (Crest) to capture the toposequence.

The site is located in a backswamp catcbanent of the Tweed River estuarine embayment.

Natural backswamp areas of the study area have been extensively modified (Tulau 1999), which changes the natural hydrological characteristics of the coastal floodplain (Sammut et al.

As the annual flood waters slowed even more away from the river, they deposited finer sediments, creating the "backswamp." This natural sorting produced a gentle incline that sloped away from the river toward the cypress swamp, which graded to marsh near sea level and Lake Pontchartrain.

Quercus lyrata-Carya aquatica EC occupies wet depressions, bottoms of chutes, slough edges, and backswamp areas.

Differences in soils were attributed to their natural levee and backswamp positions.

Intermediate backswamp areas, or chavascal, support scrubby vegetation mixed with some trees, such as the munguba (Pseudobombax munguba).

These low-lying areas of the floodplain adjacent to Fogg Dam are termed the "backswamp." In most years torrential monsoons fill Fogg Dam to overflowing and inundate the backswamp to a depth of [greater than]1 m, whereas inundation on the rest of the floodplain is [less than]0.4 m.
