An analytical solution is presented for the drawdown distribution in a large diameter well during recovery. It takes into consideration the well storage. A set of type curves are given to determine the transmissivity and storage coefficient of the aquifer. The basis of the methodology is to solve simultaneous differential equations of the water balance and Darcy laws. The application of developed methodology has been given for recovery data from India and Saudi Arabia.
