Rock mechanics and fracture flow

Rock mechanics and fracture flow

Our focus is on enhanced understanding of flow and transport mechanisms in fractured systems. We currently develop new tomographic inversion procedures for discrete fracture network (DFN) characterization. We also inspected single fracture characteristics in granitic rocks relevant for engineered geothermal systems (EGS).
