| Summary: | 碩士 === 國立成功大學 === 資源工程學系碩博士班 === 94 === This study is aimed to evaluate the groundwater resources of the Chihben Creek Basin at Taitung county in southeastern Taiwan. Since the shortage of the hydrogeological parameters, then selected the non hydrologeological parameter methods: the recession-curve-displacement method and the base-flow-record estimation method, which developed by USGS, to estimate this basin’s groundwater resources. On the other hand, this study try to research the geological data of this creek basin, and by refer to the similar geological conditions to choose the initial hydrogeological parameters, to which simulating and rating by IGW.
Been estimated the groundwater resources of the Chihben Creek Basin with three kinds of codes, the results showed that from 1980 to 2004 the average amount of annual groundwater recharge is approximately 2.24×108～2.87×108 m3.
