A closed basin scenario is on in which no water flows out of the basin, ie to the seas or oceans. All the water in the river are dedicated to certain uses already.

While this may provide short time economic gains, the overall humanity will pay a price for the destruction of the ecology through its flow into the seas and oceans.
