Abstract
Abstract: Development of Methodologies for the
Characterization of Fluvial Aquifers
Professor of Geology at TAMU-Kingsville
Software tools for groundwater modeling, such as HORIZONS in GMS, have provided modelers new tools for characterizing subsurface heterogeneity. While this approach has provided acceptable results for simplemodels, it falls short in the development of stacked aquifer sequences. Recently, groundwater modelers have been tasked to simulate the fate and transport of contaminants in complex fluvial systems. Scenarios such as these require a more detailed subsurface geometry than previous models. The primary research focus is to develop a set of procedures that compensate for the inherent weakness of the characterization process. Idealized fluvial landforms were used in the creation of these newly developed procedures to create a baseline against which further work can be calibrated and tested. The results of this phase of research include not only a more accurate representation of a fluvial aquifer but also produced a set of tools and guidelines that can be adapted for future hydrogeologic modeling.
