嘉南平原區域性地下水觀測站井佈置檢討

Abstract

本計畫目標在配合嘉南平原及蘭陽平原新設觀測井所產生之水文地質資料，配合水文地質含水層分析及區域變數理論等較嚴謹的監測網規劃分析的方法，對嘉南平原、蘭陽平原及澎湖本島等地區進行地下水觀測站網站井位置、深度等之檢討並作出具體的建議。並為配合其他地震前後地下水位變化相關研究，於台南白河及新竹、苗栗地區新站井位置配合建議一至二口觀測井。

This study examines the feasibility of installing groundwater monitoring wells with respect to their location and depth at Chia-Nan area, Nan-Yan plan, and Peng-Hu Island. The design procedure comprises data collection, review of the current monitoring network, hydrogeological analysis of aquifers, geo-statistical analysis of hydro-geological parameters and final design of the groundwater monitoring network based on the variance reduction. This study also recommends potential location of several groundwater monitoring wells on Tai-Nan, Hsin-Chu and Miao-Li areas to more thoroughly understand how earthquakes impact the variation of groundwater level.
