    摘要: 四重溪是南台灣著名的溫泉勝地。早年溫泉露頭可自然湧出溫泉,後因人為過度鑿井開發,溫泉露頭自湧泉自89年已然消失,溫泉水位日漸下降,為有效達到溫泉水資源管理,需要水位及抽水量之監測。目前四重溪地區建有 5 口監測井,井中有水位及水溫監測儀器,而於106年4月底在大山及公共浴室兩口抽水井加裝智慧水表,可即時監測抽水量與水位。本研究首度分析四重溪溫泉的抽用量及抽用行為,初步發現,105年有14家溫泉業者,一年抽水量約20萬噸,並無超過總量管制額43萬噸,但因抽用業者集中在東北邊,抽用最多是大山,其次依序為清泉,牡丹風情,與公共浴室,四家抽水量占總額76%,因此在這四家圍繞的監測井的水位最低。106年5月起,透過智慧水表監測大山及公共浴室兩口井可發現,大山農場每日抽水行為,早晚並沒有明顯的差別,周五有明顯稍多,每月平均抽水量約5442噸。公共浴室每日抽用集中於早上5點開始,8點以後稍少,推測為早起晨運民眾為主要使用者,周六日稍多,每月平均抽水量約1605噸。兩口井的夏季抽水總量偏低,且單日少量抽水,6月~9月水位呈上升趨勢,進入秋冬,日抽水量急增,10月~12月水位呈下降趨勢。大山抽水井與監測井距離7.4m,抽水井抽水量約0.05-0.25噸/min,大約在監測井產生1m的干擾。公共浴室抽水井兼做監測井,抽水量約4.5噸/時、最大洩降可達約8m。
    The Sihchongsi hot spring is a famous and historic hot spring in the southern Taiwan. The only hot spring outcrop had dried up since 2000 because the over-pumping of thermal wells of bathhouses. The previous studies show the hydraulic heads of hot spring aquifers are also declining due to the over-pumping of thermal wells since 2000. However, there is no study of withdrawal volumes of hot spring and the correlation between withdrawal volume and hydraulic heads is unclear. The purpose of this study is to analyze data of withdrawal volumes of thermal wells from 14 bathhouses in 2016 and install smart water meter in two wells—the Da-Sun and Public Bathroom in April of 2017. The hydraulic heads and water temperature have been monitoring in five wells since 2007. The data of this study show the total amount of withdrawal of thermal water for the total 14 bathhouses was approximately 200,000 m3/y in 2016 while the safe yield for the Sihchongsi hot spring area is 430,000 m3/y. The top four bathhouses for the withdrawal are Da-Sun, Cing-Cyuan, Mu-Dan-Fong-Cing and Public Bathroom with accounted for 76% of the total withdrawal amount. Therefore, the hydraulic heads of the monitoring wells around these four bathhouses were the lowest. The data from the smart water meter in Da-Sun show that there is no obvious difference in pumping behavior between day and night since May 2017. The withdrawal amount is obviously more on Fridays. The average withdrawal amount per month is about 5,442 m3. As to Public Bathroom, daily pumping time is mainly from 5 a.m. to 8 p.m. and the pumping amount reduces gradually after 8 p.m.. The pattern suggest that the main users are the people who get up early to exercise. In addition, the pumping amount is a little more on Saturdays and Sundays. The average withdrawal amount per month is about 1,650 m3. In summer, the total withdrawal amount of the two wells is much lower, and so is the daily withdrawal amount. From June to September, the head is ascending gradually. In fall and winter, daily withdrawal amount increases sharply. From October to December, the head is descending gradually. The distance between the pumping well and the monitoring well in Da-Sun is approximately 7.4 m. The discharge of the pumping well is approximately 0.05-0.25 m3/min, and that causes about 1 m drawdown in the monitoring well. In the Public Bathroom the pumping well and the monitoring well is the same one. The pumping amount is 4.5 m3/h and the largest drawdown can be up to 8 m.
