A semianalytical solution is presented for the problem of drawdown distribution in a two‐layer aquifer when the system is pumped from a well that is partially penetrating in one of the layers. The solution is used to illustrate the effects on aquifer behavior of partial penetration as well as the effect of a contrast in flow properties between the two layers. The validity of the solution has been verified against four available limiting cases. A method for analyzing field data is proposed, and an example is given to illustrate the procedure.
