River delta The Okavango Delta in Botswana is one example. The generic term "mega delta" can be used to describe very large Asian river deltas, such as the Yangtze, Pearl, Red, Mekong, Irrawaddy, Ganges-Brahmaputra, and Indus. The formation of a delta is complicated, multiple, and cross-cutting over time, but in a simple delta three main types of bedding may be distinguished: the bottomset beds, foreset/frontset beds, and topset beds. This three part structure may be seen in small scale by crossbedding. The Ganges/Brahmaputra combination delta, which spans most of Bangladesh and empties into the Bay of Bengal, is the world's largest delta.
Sacramento–San Joaquin River Delta end of the Delta. Currently, freshwater entering the Delta has to flow through a maze of river channels and sloughs before entering the Clifton Court Forebay north of Tracy, where water is pumped into the California Aqueduct and Delta-Mendota Canal. In addition, large numbers of Delta smelt and other endangered species are killed by the pumping plants that provide water for the aqueducts. The current proposal, known as the Bay Delta Conservation Plan, entails building twin tunnels under the delta and is closely associated with Governor Jerry Brown. However, the Peripheral Canal proposal has been criticized because it would further
