WebMeandering rivers contain abundant suspended sediment, which is deposited in ox bow lakes and on floodplains. Overbank deposits are better developed and finer grained in meandering river systems. Bar migration is much more regular in direction in meandering rivers because there is a well defined, single thalweg towards which the bars migrate.

WebNot all high sinuosity rivers can be categorized in terms of the meandering models described above. Smith and Smith (1980) and Smith and Putnam (1980) defined a new facies model for rivers consisting of a low energy complex of several interconnected channels of variable sinuosity, typically >1.5. WebNov 23, 2024 · As the river moves downstream, the sinuosity index of the river on the Okavango Delta decreases downstream. Based on the characteristics of different zones, the sedimentary facies model of a single source distributive fluvial system of a meandering river is proposed.
