Authors have been developed the technique for estimating hydrogeological structures, which influence the deep groundwater flow, by an inverse analysis using tilt change by an artificial impact of the underground facility construction. It is possible to complement the data from borehole investigations by using the technique based on the data obtained from surface area. This paper describes the results of evaluation for the applicability of the technique by comparing with the long-term hydraulic monitoring data.
