Required Storage based on 1973 flood + existing storage 21.5 MAF

To Arabian Sea

98.7 + 21.57 = 120.27

120

To Arabian Sea + withheld in flooded areas

98.7 + 68.7 + 21.57 = 188.97 ≈ 190 + 10% safety factor

Total Silt load = 0.1811 + 0.10332 = 0.284465 MAF/year.

Thus, it will need 334 years for silting to 50%.

Storage for multi-decadal flow regulation with Additional max. 50 MAF irrigational releases.

At least 255 + 21.57 = 277 MAF.

This will need 487 years for silting its capacity to 50%.

Decadal view

20

Storage for multi-decadal flow regulation with Additional max. 40 MAF irrigational releases in view of 34 - 37 year decadal cycle.

At least 475 + 21.5 = 497 MAF.

This will need 874 years for silting its capacity to 50%.
