Abstract: An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective function along with the constraints. The constraints are defined such that the groundwater table does not decline beyond a limit in order to avoid overdrafting. The Simplex method has been used to maximize the withdrawal volume based on the above constraint. The constraint ensures that the model results can be used to design for the sustained availability of groundwater by pumping wells throughout the pumping period. The use of the model was demonstrated by applying it to an example of an unconfined aquifer.
