AIDA – Modellkopplung HEM1D+

AIDA-Logo

The multi-disciplinary collaborative project AIDA aims to generate user-oriented information from geophysical data describing the structural characteristics of the shallow subsurface. The joint project is the GEOTECHNOLOGIEN program "Tomography of the usable underground - From sound transmission to real-time monitoring" funded by the BMBF and the DFG.

Within the BMBF joint project, BGR executes the "Project TP2 model coupling HEM1D +" and takes over the task of combining different modeling approaches and user-oriented interpretation of aero-and ground geophysical data to explore the near-surface usable subsurface on a regional scale.

By including ground geophysical and geological data into the inversion of the aerogeophysical data (HEM) this inversion should be optimized. Local conductivity structures, that can not be interpreted in one dimension (1D), should be interpreted, tracked, extracted, modeled in three dimensions and then re-integrated into the regional model structure. Both 3-D simulation as well as inversion algorithms should be used, some of them developed by the project partners. A newly developed user interface will control all imports and exports of data and models as well as linking different data sets and models.

As a result, not only a more accurate 1D inversion of HEM data by use of external data, but also an improved interpretation of complex structures by the combination of 1D and expected 3D models are to be expected.
