碩士 / 嘉南藥理大學 / 觀光事業管理系 / 103 / Hot spring is the most important natural resource for tourism in Jiaosi. However, according to the previous studies, declining water pressure and temperature in hot spring water resources in recent years. There are more than 100 hot spring spa houses in Jiaosi with a total of approximately 3000CMD of hot water withdrawn during weekdays. In peak seasons and holidays, the amount of hot water usage up to 16000CMD. The usage amount of hot spring might exceed the economical safe yield. The purpose of this research is to investigate hot water usage behavior of the spa house for understanding the distribution of production wells, and to know if the period of the maximum amount of pumping would be related to the varied seasons. This will provide a reference to maintain the sustainable operation of hot spring resources.
The daily interference drawdown (DID) is the pressure difference between the highest and lowest water pressure in one day in the monitoring well. The DID usually caused by the withdrawing of nearby wells. I use data from eight monitoring wells with water pressure recorded in a half hour interval in 2013.
The results show that 55% of the production wells are located in the upstream areas which have higher DIDs with highest value in the Tai-Zhi well. However, only 1% of the hot spring wells are in the downstream areas. Therefore, the DIDs declined to 20~40cm. Moreover, the minimum water level occurred mostly during the period from 21：30 to 0:30 in the morning, which implied that most hot water was withdrawn during the night time. The tourists tend to do activities and enjoy spa at night. Finally, the DIDs were higher in spring and autumn, rather than in winter that I assumed more spa tourists in winter because of low temperature. In winter, the Northeast monsoon results in humid weather which makes people unwilling to go sightseeing; on the contrary, the pleasant weather in spring and autumn attracts more tourists. As a result, the amount of pumping in spring and autumn is higher than that in winter.
