中文摘要 | 本文探討嘉義縣東石鄉六腳排水至朴子溪間之地下水水質及其污染物 傳輸情形。經現場取樣分析地下水之電導度、氯離子與鈉離子濃度等結果發現, 離海岸約3km範圍內之淺層含水層地下水之含鹽量極高,而深層含水層及遠離海 岸之地下水含鹽量較低。本文並以地下水污染傳輸模式模擬地下水流動及污染物 傳輸情形。文中選用二維之SUTRA軟體為模擬工具,以氯離子為傳輸關鍵物質, 模擬該物質在地下水中傳輸現象。模擬結果可說明該區域抽水與海水入侵之關 係,以做為管理沿海地下水之參考。 |
英文摘要 | The object of this study is to investigate the quality and the pollutant transportof groundwater in Tung-shih, Chia-yi. The region around the downstream and thedrainage ditch near the seashore is chosen as the study area. Electric conductivity,chloride and sodium in the groundwater were investigated. Results indicated that theupper aquifer about 3 km away from the seashore has high salt content, but it islower in the under aquifer. The aquifer greater than 3 km away from the seashorealso has lower salt content. Seawater intrusion is the main reason for groundwaterpollution. A two-dimensional groundwater tranport model (SUTRA) is used to simu-late the concentration of chloride variation in the groundwater and it is found thatthe relationship between pumping and seawater intrusion can be described by thesimulation result. |
