My professional life has been devoted to developing, testing and applying a wide variety of computational methods for analyzing fluid flow phenomena, some of which were mathematical models developed to tackle and solve complex practical problems. I have also conducted expert investigations in matters involving mathematical modelling of ground water and surface water systems and provided expert testimony.

Expert-Witness Experience

During approximately the last thirteen years, sixteen of the scientific and engineering project investigations conducted by my staff colleagues and myself at Principia, included provision of litigation support involving ground water, surface water and atmospheric flows of fluids. Within that time period, I have served as an expert-witness in ten cases. In each case, I was qualified as an expert in the fields of fluid mechanics, hydrology and contaminant transport, mathematical modelling, computational methods of analyzing data and atmospheric dispersion. In addition to conducting scientific investigations in these cases, I have also provided expert witness testimony in trial proceedings where I was cross-examined, and/or was deposed.

Two of these cases involved water rights issues in Colorado. The first was the U.S. Supreme Court case known as Kansas v. Colorado in which I was responsible for modelling of complex ground water flows and stream-aquifer interactions in the Arkansas River Basin among other matters, on behalf of Colorado. The second was the Colorado District Court case involving applications for water rights by AWDI in the San Luis Valley in which I was responsible for modelling ground water flow, steam-aquifer interactions, well pumping and vegetative consumptive use, among other matters on behalf of the Joint Objectors. Brief details of the ten cases follow.

They also included mathematical model evaluations, on behalf of Lassen County, California as well as several objectors to the applications which included the U.S. Army at their Sierra Depot. I then testified at public hearings before the authority, the Nevada State Engineer and was cross-examined.

Publications Authored or Co-Authored

I have authored or co-authored approximately sixty publications in my scientific fields of interest dealing with fluid mechanics, computational methods as well as with mathematical model applications to a variety of projects involving fluid flows and associated phenomena, in engineering processes, ground water, surface water and atmospheric systems. A number of these publications have dealt with analysis of complex ground water systems, model calibrations, model verifications, and the interactions between stream flows and local ground water systems. A list of these publications is included with my detailed curriculum vitæ.
