The Helmholtz Centre for Environmental Research (UFZ) with its 1,100 employees has gained an excellent reputation as an international competence centre for environmental sciences. We are part of the largest scientific organisation in Germany, the Helmholtz association. Our mission: Our research seeks to find a balance between social development and the long-term protection of our natural resources.
The Department of Environmental Informatics is offering a position for a Master thesis to commence at the earliest convenience.
Master Thesis: Measures for Seawater-Intrusion Remediation in Shallow AquifersThe rising demand of fresh water, for example for agricultural and industrial use, may lead to overexploitation of aquifers, i.e. pumping rates exceed the natural regain of water resources by recharge or infiltration. Declining groundwater levels and seawater intrusion are possible results. The objective of this work is to evaluate the possibility of using artificial water injections and extractions in terms of creating a negative and positive hydraulic barrier against sea-water intrusion into shallow aquifers. In this work, the overall feasibility of the barrier approach is to be analyzed under possible variations of environmental subsurface conditions and groundwater utilization scenarios.
