We present in this paper an innovative and sophisticated software environment, called Interactive Groundwater (IGW), for unified deterministic and stochastic groundwater modeling. Based on a set of efficient and robust computational algorithms, IGW allows simulating complex, 3D unsteady flow and solute transport in saturated porous media subject to both systematic and "random" stresses and geological and chemical heterogeneity. Adopting a new paradigm, IGW eliminates major bottlenecks inherent

For many problems, the new computational environment enables real-time modeling, visualization, analysis, and presentation. IGW functions as a "numerical research laboratory" in which an investigator may freely explore: creating visually an aquifer system of desired configurations, interactively applying desired stresses and boundary conditions, and then investigating and visualizing on the fly the geology and the dynamic processes of flow and contaminant transport and transformation. At any time, a researcher can pause to edit and interact on-line with virtually any aspects of the modeling process and then resume the integrated visual exploration; he or she can initiate or stop particle tracking, plume modeling, hierarchical subscale modeling, stochastic modeling, monitoring, and mass balance analyses. IGW continually provides results that are intelligently processed, organized, overlaid, and displayed. It seamlessly and dynamically merges heterogeneous geospatial data and modeling inputs and outputs into composite 2D or 3D graphical images -integrating related data to provide a more complete view of the complex interplay among the geology, hydrology, flow system, and reactive transport dynamics. These unique capabilities of real-time modeling, dynamic steering, and visual analysis significantly expand the utility of groundwater models as tools for research, education, and professional investigation. This paper is the first of a sequence of articles that introduce systematically the IGW software environment, including the new modeling paradigm, capabilities, algorithmic innovations, verifications, stochastic and hierarchical modeling, and applications.
