The site descriptive modeling, which includes modeling of geological characteristics at present and modeling of site evolution, is used for synthesis of investigation results. It is important to evaluate uncertainties in the model, to specify issues regarding the uncertainties, and to prioritize the specified issues, for the planning of site characterization. The aim of this study is to support for the planning of initial surface-based site characterization based on the technical know-how accumulated from the JAEA's Underground Research Laboratory Projects. In this study, comprehensive task flow from pre-existing data acquisition to site characterization planning through the modeling has been specified. Specific task flow and decision-making process to perform the tasks have been specified, and decision points have also been identified.
