In recent years, too many new wells were drilled and hot water was over-pumped in several hot spring areas that cause pressure of hot water decreasing and some hot spring outcrops vanished. For the sustainable use and better management of the hot-water resource, a water pressure and temperature monitoring program is setup in the Chiao-Shi hot spring area, northeastern Taiwan. This study presents the water pressure and temperature data for four wells during November 2007 to December 2008.
I suggest that rainfall and water withdrawal by wells are two major factors that cause the hot-water pressure to rise and drop. There are an annual cycle of hot-water pressure and a good correlation between hot-water pressure and precipitation in all of four wells. The higher water level occurred in September to November of rainy season and lower level in December to May of dry season. With precipitation of 350 mm at a single day of 14 September 2008, the hot-water pressure increased and water temperature dropped abruptly. At one year interval, the pressure of hot-water is lower in November-December 2008 compare with the same period of months in 2007. The decreasing of water pressure should be contributed to the over-pumping of hot-water in the Chiao-Shi hot spring area.
