The Irrawaddy
The Salween carries an estimated 108 to 237 million tonnes of sediment per year. About 92 percent of sediment is delivered to the ocean during the monsoon season. The Salween delta is physically contiguous with the Irrawaddy and Sittaung deltas. The Irrawaddy–Sittaung–Salween delta is relatively stable, with the coastline advancing an average of per year between 1925 and 2006. Sediment accumulation is largely balanced out by subsidence and transport by ocean currents. However, proposed dams along the Salween would trap much of the sediment with potential detrimental impacts to coastal erosion.
