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
Discrete fracture network in the Potucky site model – hydraulic communication of two boreholes.
Results of piezometric head in the fracture network during a particular test
Results of the fitting the time-pressure measured curve with various values of storativity (thick uneven lin e is the measurement)
