Gravity and seismic reflection applied to the hydrogeological research in a large Alpine valley

The determination of the bedrock morphology is an important parameter for the purpose of the hydrogeological research. In the case of large alpine valleys the bedrock depth may vary from few hundreds to thousand meters. Furthermore, structural differences in the sedimentary body, generally linked to lateral valley contribution, are another important parameter to take into account. In the outline of a research project of the Geological Survey of the Province of Trento (ltaly), several gravity profiles was measured in the Adige valley, neighboring the urban area of Trento. A 2.5 D model was elaborated on the base of the gravity data. Geology, borehole information and seismie reflection was used to constrain the 2.5D gravity modeling.
