Rainer Senger is a hydrogeologist with over 23 years of experience in water-resources investigations, aquifer and petroleum reservoir characterization studies, and site characterization and performance assessment of potential waste sites. He has experience with a variety of characterization methods, including well testing, tracer testing, air-permeameter measurements, and analysis of water-level variations and hydrochemical constituents. He has complemented these characterization tools with geostatistical analysis and numerical modeling techniques for deterministic, stochastic, and inverse simulations. He has been involved in a variety of investigations for hydrogeological characterization of nuclear waste sites in the U.S., Europe, and Japan. In the area of site characterization, Dr. Senger specializes in two-phase flow phenomena associated with migration of waste-generated gas from a potential waste repository, including potential coupled hydromechanical processes. He has been involved in the gas testing campaign for the French national radioactive waste disposal agency's (Andra) underground research laboratory near Bure, France, and is a team member of an international consortium headed by RWMC, Japan, for the design and analysis of the gas migration test at the Swiss national radioactive waste disposal agency's (Nagra) underground research laboratory at the Grimsel Test Site in Switzerland. In the area of water resources investigations, Dr. Senger has studied water resources and water quality aspects of many aquifers in Texas, with particular focus on the Edwards Aquifer in central Texas, and has been the modeling technical manager for developing regional-scale groundwater models for the northern and southern portions of the Carrizo-Wilcox Aquifer. In addition, he has investigated basin-scale groundwater flow involving variable-density effects in the Palo Duro Basin of Texas, and has simulated salt-water intrusion scenarios of coastal aquifers.
