The hydraulic characteristics of a layered ground‐water system are determined by a modified digital model. Its use provides information on the hydraulic conductivity and storage coefficient of a stratum and on the transmissivity and storage coefficient of the ground‐water system as a whole. These characteristics are determined by trial‐and‐error test runs until the calculated drawdowns reasonably match drawdown data from observation wells which are open to the artesian aquifer and to the confining beds above or below. An aquifer test of a layered ground‐water system in Palm Beach County, Florida shows that the transmissivity of the ground‐water system as a whole is 50 percent higher than just the transmissivity of the major water‐bearing zone in this system.
