The Ayeyarwady River, also referred to as the Irrawaddy River, is located in Southeast Asia and is the main river in Myanmar (Burma). It is about 1,350 mi (2,170 km) in length. The river rises in northern Myanmar, flows southward through the center of the country, and discharges into the Bay of Bengal and Andaman Sea through nine river mouths. These mouths form the 13,500 mi2 (35,000 km2) Irrawaddy Delta. The rivers are heavily silted with turbid waters and the delta is actively accreting seaward, forming a wedge shape.
