碩士 === 國立屏東科技大學 === 土木工程系所 === 96 === Because of the population increased in Taiwan in recent years, the economy grew fast, the social structure rapid change, the water resource used demand therefore increased dramatically, to solve the water demand problem and the water resources multi-functional development in Pingtung Plain, the study discussion feasibility in the Kaoping Lake pilot for aquifer dynamic behavior and the infiltration mechanism analysis. The study of results, in groundwater level, there had the bubbling spring phenomenon in partial region, in rainy season and dry season the water level below the surface at ca.2~4m. From recharge experiment, the recharge amount and infiltration rate is balanced by 500 CMD and 350 CMD respectively. When the hydraulic head is 1.5 m, the hydraulic conductivity is 1.16~1.71×10-4 cm/sec at the bottom of pond which belongs to the low permeability. The infiltration rate reduce is resulted from the sediment cogging.
