Analysing the long term reduction in groundwater temperature due to pun pumping
1995
TANIGUCHI, MAKOTO
A heat transport model that incorporates the effect of decreases in hydraulic head due to pumping of groundwater has been developed to explain the decrease in groundwater temperature during the last three decades in the Nara basin, Japan. Vertical two-dimensional temperature analyses have been made based on a theory of simultaneous transfer of heat and water in porous media. The calculated relationships between the depth and the groundwater temperature in the discharge area agree well with the observed temperature-depth relationships. The model used suggests that the decrease in groundwater temperature is caused by the decrease in the hydraulic head due to pumping.
