Testing a parsimonious ground water model in the Silberleite catchment, Moxa Germany

The Geodynamic Observatory Moxa is located 30 kilometres south of Jena, Thuringia Germany in the narrow valley of the Silberleite. A superconducting gravimeter, which measures changes in the earth’s gravit field, is located in the observatory. The gravitational field is not only influenced by tectonic activity, but also by the hydrological situation in the vicinity of the gravimeter. In a Previous study, a steady state 3D-model of the area directly around the observatory was constructed. The objective of this study was to gain an understanding of water storage and water flow on the hill slopes around the observatory and to create a dynamic linear reservoir model for the hill slopes. This reservoir model is used to transform the steady state 3D-model into a transient model.
