礁溪溫泉於2007年開始進行水位及水溫之監測,至2011年已累積了5年之數據,從早期4口監測井至今已增為11口,數據正大量的累積當中,本研究即為應用電腦程式處理這些數據,並討論其意義。
本研究分為二方面:資料處理及意義之解析。資料處理部份,因早期各井之記錄頻率並不相同,有10、15、30及60分鐘,導致各井數據長短不一,很難綜合比較。本研究將各數據整合為30分鐘一筆記錄,提供各井間做比較。並撰寫日平均程式,將各年數據(17520筆)濃縮為365筆,以利長期分析。
從歷年數據發現,2007-2011年水位,以JS015大忠路最低、井口下15.16m,福崇寺井水位為自湧狀態。其餘各井水位約井口下1-6m間。R003太子井下降1.01m,主因為該井旁的建築工地,因開挖地下室抽水,導致7-10月水位大幅下降。但R004國小井下降0.48m。
2009-2010年的監測井年均溫,JS003-1公園井上升0.96℃。JS015大忠井下降1.07℃。R003太子井3-9月上升、10月後下降,溫度升降幅度超過10℃,主因為該井旁的建築工地,因開挖地下室抽水,導致水溫變化。R004國小井上升0.65℃。 Abstract
The monitoring of water level and temperature in hot springs wells of Jiaosi has been conducted for five years from 2007 with only 4 wells to 2011 of 11 wells. As the great amount of data are accumulating and its inconsistency of data format, I write some computer programs to process the data and discuss its significance.
The monitoring data are composed by a variety of sampling time interval, i.e. 10, 15, 30 or 60 min. I reprocess those data to 30 min of time interval. Also, a program is developed to calculate the daily average of water level and temperature for the 30 min time interval database.
The water level (from the top of casing, TOC) of well Js015 is about 15m which is the lowest in the hot spring area. The well Js015 is located at the western margin of the hot spring area. The highest water level is at the northwestern part which is the source area of hot spring water. The water levels of other wells are about 1-6 m TOC. There was a period of significant decline of water level in July to October 2010, because the dewatering pumping during the construction of an apartment building.
Some well’s temperature were higher and some wells were lower in the monitoring period of 2007-2011. During the construction of the apartment building, the temperature of a well near the site was decreased because of the shallow groundwater flowed downwardly.
