AQMODL is an analytical mathematical aquifer modeling program for the HP‐41C handheld programmable calculator. It does not require any written instructions for its use. It guides the operator through its use and prevents operator error. It is designed so that it can be used by anyone only basically familiar with the operation of the HP‐41C calculator, and with aquifer modeling. There are no special key assignments, and no special data preparation or storage operations or any other prior preparation necessary before running AQMODL, simply XEQ AQMODL and follow the calculator’guidance. AQMODL can be used to model simple or complex single aquifer situations. It considers any regional change (rising or falling) in water level not necessarily associated with the development being modeled. It also models the aquifer's water‐level gradient. Sixty pumping and/or recharge wells can be entered into the model, and the resultant change in water level and water‐level elevation determined at an unlimited number of observation points in the aquifer.
