地下水流動と物質輸送・熱輸送

抄録

An overview of studies on mass and heat transports due to groundwater flow has been made. Evaluations of groundwater flow system, recharge and discharge areas, and capture and release zones, are keys to understand the mass and heat transports in subsurface hydrological regime. Groundwater flow and mass/heat transports should be studied including the effects of interaction between surface water and groundwater, and global environmental issue such as global warming on subsurface thermal regime. A link model of groundwater flow and solute transport with data base and GIS enable us to evaluate the effects of land use change and pumping on subsurface water, mass and thermal regimes. This kind of link model is useful to predict the change in hydrological environment, therefore, it will be a good tool for water, land use and environmental managements.
