碩士 === 國立成功大學 === 資源工程學系碩博士班 === 97 === This study investigated the effects of the geostatistical simulator on the hydrogeology fields, two simulated techniques are applied: the indicator cross variogram function and transition probability function. The resulted connectivity of the flow field are explored. The study area is a contaminated site in Tainan. The major integral range in horizontal direction is about 272m and the minor integral range is 50m, the vertical integral range is 5m. Using the transition probability, the high hydraulic conductivity soil continued in horizontal direction is found to be 300m and the mean length is about 700m, while the low hydraulic conductivity soil continued in horizontal direction is 100m and the mean length is 120m, and the high hydraulic conductivity soil continued in vertical direction is 5m and the mean length is 3.7m, the low hydraulic conductivity soil continued in vertical direction is 3m and the mean length is 1.2m. The simulation resulting using the transition probability are found to be with a higher connectivity which may result in a faster transport path of contamination.
