The TOPSOIL Project - Integrated Approach of Near Surface Geophysics and Groundwater Modelling

To ensure a sustainable freshwater supply good knowledge of the aquifer system is essential. Especially in coastal areas water quality is threatened by seawater intrusion and extensive withdrawals. The aim of our study is an integrated approach of geophysical methods and groundwater modelling to provide the data base for groundwater management strategies. The study area is located in North-Western Germany, where aeroelectromagnetic data are available. Additionally, ground based geophysical measurements for aquifer structure and properties are planned (e.g., 2D electrical resistivity, magnetic resonance soundings, ground-penetrating radar, seismic reflection profiles). The study is in progress and part of the INTERREG North Sea Programme project TOPSOIL.
