Description :
Three classes are recognised : 1) high-energy non-cohesive; 2) medium-energy non-cohesive; and 3) low-energy cohesive floodplains. Thirteen derivative orders and suborders, ranging from confined, coarse-grained, non-cohesive floodplains in high-energy environments to unconfined fine-grained cohesive floodplains in low-energy environments, are defined on the basis of nine factors (mostly floodplain forming processes). Finally, it is proposed that, because floodplains are derivative of the parent stream system, substantial environmental change will result in the predictable transformation of one floodplain type to another over time.
