Pointbars are typically composed of sands, gravel, silts, and clay deposits, that form arcuate, meanderscroll ridges. Fluvial systems are extremely susceptible to a range of environmental factors. Depositional model of fluvial deltaic architecture of braided stream deposits walker and cant, 1984. The fluvial processes include the motion of sediment and erosion or deposition on the river bed. It focuses on the preserved, ancient depositional record and emphasizes largescale basinscale depositional processes.
The thick and sometimes stacked and amalgamated sandstones of the bridgeport channel facies could have formed in such an environment. Fluvial depositional landforms types of deltas pmf ias. The decrease in stream velocity reduces the transporting power of the streams which are forced to leave some load to settle down. A read is counted each time someone views a publication summary such as the title, abstract, and list of authors, clicks on a figure, or views or downloads the fulltext. Fluvial environments include braided and meandering river and stream systems. Tectonic and climatic controls of fluvial sedimentation and the effects of baselevel change on sequence architecture are discussed. The depositional action of a stream is influenced by stream velocity and the volume of river load.
