yes. the red area would be the reservoir held back by the dam.
It receives heavy rainfall and Brahmaputra water. This would desalinate the body of water over time.
The dike would have some type of submerged floodgates near the bottom. When the dam's level is higher than the ocean, you open the gates, and salt water goes out. When the dam's level is LOWER than ocean, you shut the gates, and ocean water doesn't come back in.
Theoretically, this reservoir of water would be totally desalinated in 4 years this way. Then it could be piped into those relevant areas for greening.
note, I'm not a civil engineer or anything, feel free to point out why this wouldn't work, but it just seems like it would. it's just fluid pressure equations
