“…With the current technological developments, small computers provide an efficient means for interactive graphic computation. The FE3DGW code [Gupta et al, 1979] for simulation of large, natural groundwater systems in PDP 11 series is an example of a program developed for use on small computers. Through a set of supportive programs to FE3DGW, input data can be verified by plotting grids, stratifications, and elevations or thicknesses of each layer.…”

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.

Groundwater flows and travel times were analyzed under a landfill site characterized by a thick unsaturated zone, in an arid environment, using two-dimensional models. Transport in the unsaturated zone is important in arid environments with thick vadose zones and usually determines the travel time of groundwater from the landfill site to the regulatory compliance surface. The combined use of a parallel flow (Dupuit-Forchheimer) areal model and vertical cross-sectional model is explored at a site typical in the utility industry. Flow paths and travel times to the compliance zone are obtained for use in landfill site design or environmental impact assessments. Sensitivity analysis shows that boundary conditions are important factors influencing the entire analysis and thus need to be confirmed with field measurements.

“…For the Cold Lake and Swan Hills areas presented subsequently, the model FE3DGW developed by Pacific Northwest Laboratory, U.S.A. (Gupta et al 1979(Gupta et al , 1984, was used to simulate the natural steady-state flow conditions and the hydraulic effects of deep waste injection. We shall now summarize the results of modelling fluid flow in the Cold Lake and Swan Hills areas, Alberta, in terms of simplified block diagrams of the model areas showing the input and output flow rates and the rates of crossformational flow.…”

Basin analysis must include an appreciation of both the rocks and the processes affecting their contained fluids. Therefore the objective of dynamic basin analysis is to synthesize and evaluate the present geological, hydrogeological, thermal and geochemical situation of sedimentary basins as well as their past history. For sedimentary basins such as that in western Canada, where petroleum exploration has resulted in a vast amount of information, synthesis and evaluation can only be achieved through an integrated multidisciplinary computer-oriented approach. This requires the development of a data-base management system and specialized data-processing techniques. These have been developed by the Basin Analysis Group of the Alberta Geological Survey for geological, hydrogeological, thermal and hydrochemical parameters. The synthesized information can then be integrated into a descriptive steady-state model which forms the basis of the numerical simulation of various processes and phenomena related to present fluid, heat and mass flows in the subsurface. These techniques have been applied to studies of the baseline hydrogeology of the Cold Lake oil sands deposit area and the deep waste disposal site at Swan Hills, Alberta, Canada. They are also applicable to petroleum exploration, in situ oil recovery, gas storage, geothermal resource evaluation and mineral exploration. Future research directions are to focus on the inclusion of models for mass transport and on the determination of the palaeohydrogeological regimes in sedimentary basins. Approach to basin analysisConventional basin analysis is concerned with the structural, stratigraphic and palaeogeographic study of large, regionally disturbed packages of sedimentary rocks. The last two or three decades have seen a major revolution in the techniques of basin analysis, which now occupies the attention of a wide range of specialists including stratigraphers, sedimentologists, palaeontologists, structural geologists, geophysicists and geochemists. Five fundamental changes have occurred over this period in the science of sedimentary geology:
