(WESTERVILLE, OH — June 5, 2014) Dr. Rainer H. Helmig will offer two lectures in the 2015 Henry Darcy Distinguished Lecture Series in Groundwater Science, the National Ground Water and Research Educational Foundation announced today.
Helmig is head of the Department of Hydromechanics and Modelling of Hydrosystems at the Institute for Modelling Hydraulic and Environmental Systems, University of Stuttgart, Germany.
The first of his two lectures is titled “Evaluating the Competitive Use of the Subsurface: The Influence of Energy Storage and Production in Groundwater.” In this lecture, Helmig will provide insight into how advanced numerical models may be used to analyze and predict the mutual influence of subsurface projects and their impact on groundwater reservoirs, and the expanding need to do so.
For example, as the subsurface is increasingly being used both as a resource and as an energy and waste repository, resource conflicts are becoming more common and complex, such as thermal energy storage and the effects surrounding hydraulic fracturing in both geothermal and shale gas production.
During this lecture, participants will learn about:
The second lecture is titled “Modeling and Analysis of Soil-Moisture Processes in the Subsurface: The Influence of Evaporation and Salt Precipitation in Groundwater.” In this lecture, Helmig will explore how soil-moisture processes in the subsurface play a crucial role in the hydrological cycle and the groundwater budget.
Understanding soil-moisture conditions in this zone is of interest in various applications in hydrology, such as land-atmospheric interaction, soil evaporation and evapotranspiration, and climate modeling, as well as emerging problems in assessing the risk of, for example, the leakage of carbon dioxide or methane from deep geological formations to the shallow subsurface that affects groundwater quality and vegetation.

NGWREF, founded in 1994 as an IRS-approved public charity, is operated by the National Ground Water Association as a 501(c)(3) public foundation focused on conducting educational, research, and other charitable activities related to a broader public understanding of groundwater.
NGWA, a nonprofit organization composed of U.S. and international groundwater professionals — contractors, equipment manufacturers, suppliers, scientists, and engineers — is dedicated to advancing groundwater knowledge. NGWA’s vision is to be the leading groundwater association that advocates the responsible development, management, and use of water.
