Applications of three-dimensional geoscientific mapping and modeling systems to hydrogeological studies

Abstract

Three-dimensional Geoscientific Information Systems (GSIS) are being evaluated in support of 3-D ground-water modeling activities at several scales and for a variety of hydrogeologic conditions. The complexity of the ground-water flow systems may be more readily modeled and understood if a 3-dimensional ground-water modeling approach is integrated with a true 3-dimensional geologic model. The process of hydrogeological analysis may be considered in terms of four fundament modules: 1) subsurface characterization; 2) three-dimensional GSIS; 3) statistical evaluation and sensitivity analysis; and 4) ground-water flow and transport modeling. These concepts have been tested using a case study at a site along the Platte River near Denver, Colorado. -from Author
