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.
Indus River Delta Indus River Delta The Indus River Delta (, ), forms where the Indus River flows into the Arabian Sea, mostly in the Southern Sindh province of Pakistan with a small portion in the Kutch Region of the Western tip of India. The delta covers an area of about 41,440 km² (16,000 square miles), and is approximately across where it meets the sea. The active part of the delta is . The climate is arid, the region only receives between of rainfall in a normal year. The delta is home to the largest arid mangrove forests in the world, as well
