中文摘要 | 以時間-頻率域之頻譜分析研究臺北盆地河流與地下水位之頻譜反應,得知臺北 盆地淡水河與新店溪下游及部份地下水位之半日、一日與1/3日水位波動頻率與天文潮相 同。M□主要太陰半日潮與K□全日性日月合成潮自臺灣海峽延著淡水河傳遞至大漢溪下游 之新海橋站及新店溪下游之中和。蘆洲、五股、三重、二重及中和等地下水位亦反應出與 M□及K□潮相同頻率之波動。1/3日水位波動頻率與材a潮相同,出現於淡水河口、土地公 鼻與新海橋河流水位及蘆洲、五股、三重、二重等地下水位,但能量較小。三重地區地下 水則有週期6.24小時之不明原因之波動現象。 |
英文摘要 | The purpose of this study is to analyze the spectral response of the tidal river and groundwater in Taipei Basin by using spectrum method in time- frequency domain. It is shown that Tan-Shui river and part of groundwater stations reveal the fluctuation of frequency with semidiuranl, diurnal and ter-diurnal tide. The semidiumal M□ and diurnal K□ tide propogate along Tan-Shui river from Taiwan Strait up-stream into Ta-Han Stream and Hsin-Tien Stream. Lu-Chou, San-Chung, Erh-Chung, Wu-Ku and Chung-Ho areas clearly reveal the tidal responses of M□ and K□ in the groundwater level. The ter-diurnal response may be related to M□ tide for all three river stations and part of groundwater stations, even though its energy is smaller than M□ and K□. There is unknown distrubance of groundwater level of period about 6.24 hours near San-Chung and Erh-Chung stations. |
