In this study, a laboratory analog is used to simulate the conduit and matrix domains of a Karst aquifer. The conduit domain is located at the bottom of the transparent plexiglas laboratory analog and glass beads occupy the remaining space to represent the matrix domain. Water flows into and out of the two domains separately and each has its own supply and outflow reservoirs. Water and solute are exchanged through an interface between the two domains. Pressure transducers located within the matrix and conduit domains of the analog provide data that is processed and stored in digital format. Dye tracing experiments are recorded using time-lapse imaging. The data and images produced are analyzed by a spatial analysis program. The results present a plausible argument that laboratory analogs can characterize groundwater water flow, solute transport, and mass exchange between the conduit and matrix domains in a Karst aquifer. The analog affirms the predictions of a numerical model and demonstrates the need of laboratory analogs to provide verification of proposed theories and the calibration of mathematical models. Quantification of solute and water exchange between conduit and matrix domains is needed is for accurately modeling groundwater flow and transport processes and that information is provided by this experimental study. / A Thesis submitted to the Department of Geological Sciences in partial fulfillment of the requirements for the degree of Master of Science. / Fall Semester, 2008. / November 19, 2008. / Calibrate Numerical Model, Matrix Domain, Conduit Domain, Solute Transport, Groundwater Flow, Karst, Matrix, Conduit, Flow Cell, Laboratory Model, Bench Top Model, Hydrology, Laboratory Analog / Includes bibliographical references. / Bill Hu, Professor Directing Thesis; Stephen Kish, Committee Member; James Tull, Committee Member.
