摘要
本研究探討地下水三氯乙烯的傳輸行為。使用考慮移行、延散及吸附等機制之數學模式分析地下水一維流模場試驗數據。
地下水一維流數學模式預測地下水三氯乙烯的傳輸行為與模場試驗觀測吻合。移行、延散及吸附為地下水三氯乙烯傳輸的主要機制。地下水一維流數學模式輸入參數值包括：(1)移行項，地下水滲流速度v = 12 m/day；(2)延散項，延散係數D = 9.1 m2/day；及(3)吸附項，吸附分配係數Kd = 16.4 L/kg。

Abstract
This thesis investigated the transport behavior of trichloroethylene in aquifers. One-dimensional groundwater models taking advection, dispersion and adsorption into account were used to analyze the pilot data.
The transport behavior predicted from the one-dimensional flow model agreed well with the pilot data. Advection, dispersion, and adsorption were the dorminant mechanisms for the transport process of trichloroethylene in aquifers. The parameter values of model input were as follows: groundwater seepage velocity = 12 m/day, dispersion coefficient = 9.1 m2/day, and adsorption equilibrium coefficient = 16.4 L/Kg.
