Description: Das Projekt "Natürliche Einflussfaktoren auf das Verhalten heißer und salinärer Quellen in der Taupo Vulkanischen Zone (TVZ) und den Norddeutschen Becken (NEGB)" wird vom Umweltbundesamt gefördert und von Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum durchgeführt. Hot and saline springs have implications for deep geothermal energy exploration and groundwater utilization and contamination and are of great scientific and economic interest. Springs are surface manifestations of coupled processes occurring at depth in the Earth. In this regard, the TVZ and the NEGB represent two end members in terms of the hydrology and thermodynamics encountered. In the TVZ hot springs often exhibit spectacular behaviour such as vigorous boiling, while in the NEGB springs occur in association with geological salt formations and exhibit a complex behaviour due to the buoyancy effects caused by salinity and temperature gradients. This project proposes to develop detailed numerical models of spring behaviour for both settings. The study will provide insights in the dynamics of springs resulting from flows through fracture systems connecting the deeper (hot and saline) aquifers and shallower (fresh and cold) surface waters. The goal is to understand their behaviour under environmental stresses such as those induced by geothermal developments in the TVZ and to explain the overall dynamics of saline springs with respect to the regional fluid migration in the NEGB.
