Thermal processes and storage in shallow aquifers
Convener: Peter Bayer  | Co-Convener: Philipp Blum 
 / Attendance Thu, 11 Apr, 17:30–19:00  / Red Posters

Thermal processes in shallow aquifers are of interest for hydrogeological analysis, for development of field experiments as well as they are of importance in the context of shallow geothermal aquifer use. Hydrogeothermics combines hydrogeology and geothermics, and delineates a trans-disciplinary research area that is dedicated to thermal phenomena, processes and technologies in water-saturated geological systems. Of growing interest are thermal processes in shallow aquifers, which are studied for different purposes. In research and practice, focal points are the realistic characterization of subsurface hydraulic and heat transport, the seasonal and long-term development of thermal conditions in aquifers, the heat transfer across aquifer boundaries, as well as geothermal energy use, long term performance of geothermal systems and their environmental performance. This session seeks contributions on the following subjects: 1) new hydrogeothermal case studies; 2) thermal response tests (TRT) and hydraulic well tests; 3) heat as a tracer; 4) new drilling techniques; 5) geochemical implications; 6) environmental impact assessments and technico-economic analyses; and 7) conceptual, analytical and numerical models of subsurface heat flow in shallow aquifer systems (< 1000 m). The session seeks to provide an overview of the current and future hydrogeothermal research, and sets its technological focus on shallow geothermal energy systems such as ground source heat pump (GHSP) systems, groundwater heat pump systems (GWHP) and aquifer thermal energy storage (ATES) and other underground thermal energy storage (UTES) systems.
