In this study, we constructed the spatial model for permeability and water-quality distribution in an analytical area (L = 12 km, W = 8 km, H = 1.5 km), with an existing Multi-scale Modeling method used for geology in Tono area. We recognized that a part of lineaments over 2 km length locate on a boundary between permeability or water-quality divisions from comparing these models with an existing fracture distribution model. Multi-scale Modeling method used for this study can be applied for a method to predict heterogeneous hydraulic structures distribution in rocks.
