. A large finite element program has been adapted to a PDP‐11/23 minicomputer to obtain the advantages of an interactive computer system. The program used is UNSAT2, a code for unsteady, saturated and/or unsaturated flow of ground water. The advantages and disadvantages of this type of system in terms of the potential for its use in mine hydrology and related areas are considered. Some of the advantages of this interactive system are: (1) ease of data input by the use of a digitizer; (2) the opportunity to review all output files and to select for printing only those of interest; and (3) the opportunity to change the physical boundaries of a problem at any desired time to make use of new information as a project progresses. This feature is particularly useful in mine‐related water inflow predictions. This characteristic facilitates the simulation of flow into a vertical mine shaft as the shaft is being developed. A problem presented to demonstrate this feature illustrates some of the above advantages. The major disadvantage is increased computational time. However, the authors believe that this disadvantage may not be particularly great because many organizations are not required to cost‐account time on a minicomputer whereas this may not be the case for large machines.
