To obtain accurate and reliable solutions for site investigations, the derivations of mathematical theories, developments of numerical models, formulations of conceptual models and the associated assumptions, applications of field-scale problems, and the parameter estimations and calibrations are recognized to be the important procedures. Motivated by the requirements to obtain the reliable assessments on groundwater flow and transport on sites, this study employ well developed numerical models such as FEMWATER(Three-Dimensional Finite Element Model of Water Flow Through Saturated-Unsaturated Media), MODFLOW (Modular Three-Dimensional Groundwater Flow Model) associated with MT3DMS (A Modular Three-dimensional Multispecies Transport Model),and IGW (Interactive Groundwater) to investigate in deep the simulation technologies for groundwater flow and contaminant transport. The main topics of the study will include (1) mathematical theories and numerical algorithm for groundwater flow and transport, (2) general concept on creating conceptual models from existing physical models (or in situ conditions), (3) mathematical and numerical algorithms for handling common hydrogeological boundary conditions, and (4) synthetic and realistic case studies by using interactive software environment for groundwater flow and transport modeling. The objective of the study is to develop a rigorous procedure to conduct groundwater flow and transport simulations, especially for assessments on potential sites for nuclear geologic repositories. Additionally, a series of internal workshops and short courses will be held to provide platforms for discussing key technologies for site specific problems. 研究期間:10001 ~ 10012
