Rivers Feeding the Andaman Sea

The Andaman Sea (eastern Indian Ocean) receives flow from major rivers of Myanmar, Thailand, and Malaysia:

Major Rivers (North to South)

1. Salween (Thanlwin) River – 2,800 km from Tibetan Plateau through Myanmar. Largest sediment load.
2. Irrawaddy (Ayeyarwady) River – 2,170 km, Myanmar's lifeline. Massive delta (Yangon).
3. Sittaung River – Shorter, steep, high sediment, Gulf of Martaban.
4. Mekong River – Minor distributary via Bassac reaches Andaman (main flow to South China Sea).
5. Chao Phraya River – Thailand's central artery, Bangkok, delta at Gulf of Thailand (connected to Andaman via Strait of Malacca).
6. Mae Klong River – Western Thailand, Gulf of Thailand.
7. Bang Pakong River – Eastern Thailand, Gulf of Thailand.
8. Prachinburi River – Tributary of Bang Pakong.

Notes

• Salween & Irrawaddy deliver ~80% of freshwater/sediment to Andaman.
• Myanmar rivers are largely undammed (Salween free-flowing)—globally rare.
• Mangroves at deltas (Sundarbans-like) critical for fisheries, cyclone protection.
