Using a three‐dimensional, isoparametric, finite‐element scheme, a computer model (FE3DGW) is developed to simulate the steady state and transient behavior of large, natural, multilayered groundwater systems. A hydrologic basis for developing a finite‐element grid is presented. Graphical displays generated by the supportive programs of the model and used to verify the input data of large, natural groundwater systems and to facilitate the interaction between modeler and field hydrogeologist are also presented. Model applications are illustrated with the simulation of a groundwater reservoir beneath Long Island, New York. The finite‐element solutions are compared with electric analog model of the same region.
