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.
Mississippi River Delta the nation's most productive and important natural assets. Consisting of natural levees, barrier islands, forests, swamps, and fresh, brackish and saline marshes, the region is home to complex ecosystems and habitats that are necessary for sustaining its unique and vibrant nature. In addition to the environmental factors, the Mississippi River Delta also provides numerous economic resources and benefits that are unique to the region. These vital resources are at constant risk of being lost with the continual land loss and the decreasing size of the natural coastal area. The Mississippi River Delta has a strong economy which relies heavily on
