Groundwater management for Lower Indus Basin

The present study aims to find out an optimum policy for pumping out the optimized volume of groundwater obtained from the authorsʹ earlier Two Level Optimization Model [N.K. Garg, A. Ali, 1998. Two level optimization model for Lower Indus Basin. Agric. Water Manage. 36, 1–21] for the Dadu Canal Command of the Lower Indus Basin. It is shown that the tubewells in this canal command may be operated at their maximum capacities to pump out the required volume of water to get the overall benefits. The groundwater hydraulics simulation model results show the development of serious waterlogging problem in the lower reaches of the command. It has also been studied that by suitably increasing and placing the tubewells, the waterlogging problem can be tackled very effectively.
