What is a Closed Basin Scenario (Water)?

I am currently doing water research and I came across "a closed basin scenario". 

What is a closed basin scenario?

1. 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.

   This is the thought process for the river basins in India. All surplus basins are being diverted to basins where there is a shortfall of water. 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.

2. In completely closed basins, all utilizable water is committed to present uses. An increase in depletive use in one part of a closed basin requires a decrease in another part. (Please refer to IWMI report 49).

3. A closed basin has no or minimal exchange of materials to the outer basin, ie. both water and air. Though it has exchanges of physical factors eg. heat, temperature, pressure, etc.

4. Closed Basin: It means close loop water cooling system. In closed loop basin system evaporation losses are minimal and easy to maintain water chemistry.

5. As in the Great Basin, U.S. Nevada and Utah have rivers that flow to inland terminal lakes rather than to the sea.

7. Do not over complicate this.   When there is more than enough water in a river basin to satisfy demand, water will flow out of the basin and into the sea.  This is desribed as an open basin .  As demand for water increases within the basin the outflow is gets less.  When there is no useable water flowing into the sea, the basin is said to be closed .    

8. A Closed Basin Scenario (water) should be seen as a build-up closed loop system for integrated water management to promote re-use, recovery, recycling and treatment of water flow within a basin to mininise water losses and encourage internal recharge in the closed basin, thereby maintaining a balance water budget. However, evaporation and precipation (evapotranspiration) should be considered within the scenario definition as assumptions.

   1. Using the microbial bioremediation technology the closed system is system is sustainable. The test done in the Saudi desert  in the early 90,s was able to use the 4 inches a year of rain to supplement that which was lost due to a) evaporation, b) home veggie garden and flowers, and c) their urine moisture lost at their city office jobs. At the end of the one year social experiment the 100 gallons of water given at the start  actually had 110 gallon balance. Due to the increased evapotranspiration the humidity level had caused a slight increase in the annual rainfall levels. Apparently when using your organic waste and burying it causes the desert to become agriculturally sustainable. In 20 years they will be able to call it the Saudi National Forest. If they want such things.

10. A closed basin is any body of water that receives surface water (input), but does not give out water (runoff). Lake Chad for example, is a closed basin lake...rivers flow into it & no river flows from it.

11. In the context of stormwater infrastructure, it is a retention basin that retains the volume of run off it was designed for, with no facility to discharge via any means other than infiltration to the ground. 

12. stagnant no flow.
