Outline of Final Research Achievements

In this study, case study as such is described for a model city in Hyogo Prefecture. First, a 3-D stratigraphy model near ground surface was established based on the existing borehole data, a total of 432. Second, the water-retention characteristics of unsaturated surface soil above the ground water level were measured by performing in-situ infiltration test. Third, the 3D seepage flow analysis by considering these characteristics was carried out, and the results were evaluated by comparing the predicted ground water level against the field observation. Finally, a map for rainwater infiltration is proposed. It was manifested that the accuracy and reliability when predicting the fluctuation of ground water level were greatly enhanced by considering water retention characteristics of surface ground. Furthermore, any risk for secondary geo-hazards will be greatly reduced by installing seepage facilities based on the proposed map.
