A genetic classification of floodplains

摘要: Abstract Floodplains are formed by a complex interaction of fluvial processes but their character and evolution is essentially the product stream power sediment character. The relation between stream's ability to entrain transport erosional resistance floodplain alluvium that forms channel boundary provides basis for genetic classification floodplains. Three classes recognised: (1) high-energy non-cohesive; (2) medium-energy (3) low-energy cohesive Thirteen derivative orders suborders, ranging from confined, coarse-grained, non-cohesive floodplains in environments unconfined fine-grained environments, defined on nine factors (mostly forming processes). These result distinctive geomorphological features (such as scroll bars or extensive backswamps) distinguish each type terms genesis resulting morphology. Finally, it proposed that, because derivatives parent system, substantial environmental change will predictable transformation one another over time.
