| Summary | The Blue Transition project accounts for the complex and cross-cutting relationships between climate adaptation and water management. In the framework of this project, a drone-based electromagnetic study targeting groundwater systems in northern Germany was performed. This research seeks to improve and advance the use of multi-patch drone-based EM inversion for groundwater exploration and aids in the development of a hydrological model to evaluate the impacts of climate change on groundwater. Data was collected over a 4 km² area, divided into seven flight patches and measuring with four different transmitter locations. Initial inversion results using data from two of the transmitter, including Bx and Bz components, show promising outcomes, identifying the fresh/saline water boundary between 50 and 150 m depth and resolving the conductive zones with deep salinization. The survey area exhibits signs of salinization with 3D conditions, making sAEM a preferred method for investigating deep salinization zones. |
