Transformation of transmissivity from derivative of pressure traisnet data obtained from hydraulic packer testing has applied to the testing data from fractured rock of Mizunami site Japan and Onkalo site Finland. The results show hydrogeological conceptual model for the tested area such as connectivity and continuity of the water-conducting features could be established by the proposed methodology. This method would provide useful information to the hydrogeologial and transport modeling and simulation.
