Tomography and hydrogeophysics

Tomographische Verfahren wie die Hydraulische Tomographie oder die Tracer-Tomographie bedienen sich Herangehensweisen der Geophysik, um relevante geologische Strukturen im Untergrund zu sichten und zu rekonstruieren. Unsere tomographischen Ansätze nutzen hydraulische und pneumatische Impulse, Durchbruchskurven, Temperatursignale oder Verformungen in Bohrlöchern, um tomographisch den Untergrund zu entdecken. Hierzu entwickeln wir effiziente computergestützte Inversionsverfahren und implementieren diese Ansätze anschließend in Feldanwendungen.
