A linearized solution is obtained for the unsteady, free surface seepage toward a ditch in an infinitely deep aquifer. The complex potential is defined to be the solution of a first order, linear, partial differential equation, and examination of the general solution for this equation reveals that a seepage surface cannot be imposed along the ditch boundary in the linearized model. A numerical example is treated, and it is pointed out that the same results can be used to describe the unsteady recharge of an aquifer under similar boundary conditions.
