Notizen: Unsteady flow to a large-diameter well in a confined aquifer experiencing well loss has been analyzed by the discrete kernel approach. The well storage reduces the well loss component and the well storage is effective in the beginning of pumping. The inefficiency of a well is overcome by increasing the well radius. The variation of specific drawdown in a large-diameter well experiencing well loss with pumping rate is nonlinear. The nondimensional time drawdown graph at a large-diameter well, in which the well loss component follows the Jacob's equation, is not unique but dependent on pumping rate.
