| 中文摘要 | 近年來台灣受到氣候變遷的影響,乾濕季日趨分明,尤其以臺灣南部乾濕季降雨比例高達9:1,然而以集水區水平衡概念進行水資源管理過程中,水文資料受限於空間分布且取得不易,地下水儲存量無法有效量化,因此本研究採用Brutsaert(2008)、Vogeland Kroll(1992)及Kirchner(2009)等三種低流分析方法進行流域除水特性評估,進行流域儲水特性評估,低流分析排除集水區降雨以及蒸發散的影響,探討河川流量與地下水儲存量之關係,藉由低流分析的河川消退曲線特徵化臺灣南部流域水文特徵,進而量化地下水儲存量,本研究探討臺灣南部長期的地下水儲水特性,結果顯示近十年來,八掌溪流域常盤橋測站與東港溪流域潮州測站,地下水儲存變化量為呈現下降現象。 |
| 英文摘要 | Since we have limited hydrological and precipitation data, we were not able to quantify Southern Taiwan groundwater storage capacity by water balance method. In this study, Brutsaert (2008), Vogel and Kroll (1992) and Kirchner (2009) methods were used to conduct low river flow analysis. The approach excluded the impact of precipitation and evapotranspiration thereby correlated the river flow solely and directly to groundwater storage capacity. River recession curve characterized Southern Taiwan basin hydrogeology characteristics that were used to quantify long-term groundwater storage capacity. Results of this study showed that the groundwater storage capacity of Changpan Bridge station in Bazhang River basin and Chaozhou station in Donggang River basin have declined in past decade. |
