WebDelta-plain facies typically form an upward-fining succession. Most of the coarsest fluvial sediments are deposited in distributary channels, forming point bars and channel lags. Repetitive overbank flooding forms natural levees along distributary channels and supplies silt and clay sediments to interdistributary bays.

Sediment gravity flows in flood-dominated deltaic setting

WebFlood Plain An area of alluvium-covered, relatively level land along the banks of a stream that is covered with water when the stream leaves its channel during a time of high flow. The astronaut photo shown here, which was taken above the border between Laos and Thailand in August 2015, shows the Mekong River flood plain covered with muddy water. WebBraided rivers are a type of river that form a network of many branches within a channel. They often form when the bedload sediment is high compared to the suspended load, which then helps the development of bars, creating the braided character. Fast flow and steep gradients characterize braided rivers. Much of the geometry of these rivers is ... rct 心理学
