Simulations of in-situ borehole hydraulic tests in granite massifs

  • exploration boreholes to test the host rock hydraulic properties (made by Czech Geological Survey)
  • building the computational model to fit the measured data of water pressure and discharge
  • fracture positions, hydraulic conductivity and storativity estimated
