Areas of Expertise
Dr. Heppner has over twenty years of experience applying hydrogeologic knowledge and expertise to provide technical and strategic problem solving in water resources management. His water resources work, much of which was done in support of the Sustainable Groundwater Management Act (SGMA), has included basin safe yield analysis; groundwater supply assessments; aquifer test planning, performance, and analysis; municipal well design; development of materials to support grant funding applications; groundwater monitoring program development and implementation; groundwater flow and solute transport analytical and numerical modeling in support of water resources and contaminant remediation evaluations; development of water budget and soil moisture budget models; modeling of integrated groundwater/surface water flow and sediment transport; research into unsaturated zone recharge processes in fractured rock; development of hydrologic models and data analysis tools; and collection of hydrologic field data in multiple environments.
Dr. Heppner has published articles in peer-reviewed journals related to recharge in fractured rock settings, watershed-scale hydrologic response simulation, and sediment transport modeling, and has presented at conferences on topics including basin sustainable yield estimation, salinity in shallow groundwater, numerical modeling methods, and equitable groundwater pumping allocation strategies.
