Biography

Dr. Meyer has more than 25 years of experience in applying hydrologic and hydraulic principles, model evaluation, and other methods to the solution of applied research and engineering problems. He developed and applied a methodology to estimate the combined impact of uncertainties in hydrogeologic model parameters, conceptualization, and future scenarios, and demonstrated the practicality and benefits of the methodology in applications to modeling uranium transport in groundwater and modeling groundwater flow for new nuclear reactor licensing. His experience includes applied analysis of flow and transport in soil covers, engineered barriers, and the near-field environment at waste disposal facilities, including the design and implementation of large-scale lysimeter experiments to evaluate waste form degradation. Dr. Meyer has completed technical analyses on groundwater impacts to support licensing of new nuclear power plants. He has contributed to flood hazard re-evaluations of operating nuclear power plants, which included reviews of flooding on streams/rivers, from dam failure, and from local intense precipitation. He contributed to development of a technical basis for the use of probabilistic flood hazard analysis in reactor licensing. Dr. Meyer has also contributed to the evaluation of water resources environmental impacts for the U.S. Nuclear Regulatory Commission and the U.S. Departments of Energy and Defense.
