碩士 / 國立成功大學 / 水利及海洋工程學系 / 102 / This study tried to figure out how the upwelling and downwelling of hyporheic water affects surface water. The preferred habitat of fish was identified by using statistical analysis methods. The results could be used as a reference for the restoration work. In addition, data collection of hyporheic water could be basis for extraction of hyporheic water in the future. Sampling sites were in the Wu Gou Shui River. Data was sampled from October 2012 to April 2014. In this study, two sections were sampled upstream of Xing Sheng Bridge and the downstream of Wu Fu Bridge. Then the T-test was used to validate water quality characteristics significant differences between upwelling and downwelling. Pearson Correlation Analysis and Principal Component Analysis (PCA) were used as a comparison to investigate the preferred habitat of different species of fishes. The results show that the water quality of stream water and hyporheic water were different in both upwelling and downwelling locations. Fish density, fish species number, and diversity index were higher in upwelling locations compare to downwelling locations. All the fish indicator species showed different habitat preferences.
