在这份说明中，我们提出了一个创新的软件环境，称为交互式地下水（IGW），统一的确定性和随机地下水建模。基于高效的计算算法，IGW可以模拟饱和介质中的三维（3D）非稳定流动和输运，这些介质受到系统和“随机”应力以及地质和化学异质性的影响。IGW采用了一种新的计算模式，消除了传统建模方案中的碎片，并允许充分利用当今显着增加的计算能力。对于许多问题，IGW支持真实的实时建模、可视化、映射和分析。该软件环境作为一个“数值实验室”，研究人员可以自由地探索以下内容：可视化地创建所需配置的含水层系统，交互式地施加应力和边界条件，然后在飞行中研究和可视化地质和流动和运输动力学。研究人员可以随时暂停，与建模过程的几乎任何方面进行动态交互，然后恢复集成视觉探索;他或她可以启动、暂停或恢复粒子跟踪、羽流建模、子尺度建模、随机建模、监测和预算分析。IGW不断提供动态处理、叠加和显示的结果。它动态地将建模输入和输出合并为复合二维/三维图像-集成相关数据，以提供地质、水文、水流系统和运输之间复杂相互作用的更完整视图。这些独特的真实的建模、操纵、分析和映射功能扩展了模型作为研究、教育和专业调查工具的实用性。
We present in this note an innovative software environment, called Interactive Ground Water (IGW), for unified deterministic and stochastic ground water modeling. Based on efficient computational algorithms, IGW allows simulating three‐dimensional (3D) unsteady flow and transport in saturated media subject to systematic and “random” stresses and geological and chemical heterogeneity. Adopting a new computing paradigm, IGW eliminates the fragmentation in the traditional modeling schemes and allows fully utilizing today’s dramatically increased computing power. For many problems, IGW enables real‐time modeling, visualization, mapping, and analysis. The software environment functions as a “numerical laboratory” in which an investigator may freely explore the following: creating visually an aquifer system of desired configurations, interactively applying stresses and boundary conditions, and then investigating and visualizing on the fly the geology and flow and transport dynamics. At any time, a researcher can pause to interact dynamically with virtually any aspects of the modeling process and then resume the integrated visual exploration; he or she can initiate, pause, or resume particle tracking, plume modeling, subscale modeling, stochastic modeling, monitoring, and budget analyses. IGW continually provides results that are dynamically processed, overlaid, and displayed. It dynamically merges modeling inputs and outputs into composite two‐dimensional/3D images—integrating related data to provide a more complete view of the complex interplay among the geology, hydrology, flow system, and transport. These unique capabilities of real‐time modeling, steering, analysis, and mapping expand the utility of models as tools for research, education, and professional investigations.
