Abstract
Recently, transport parameters of conservative solutes such as KCl in a porous medium have been successfully determined using time domain reflectometry (TDR) . This study was initiated to Investigate the applicability of TDR technique to monitoring the fate of a heavy metal ion in a sandy soil and the distribution of its concentration along travel distance with time. A column test was conducted in a laboratory that consists of monitoring both resident and flux concentrations of
최근 들어, 다공질 매질에서의 KCl 같은 보존성 용질의 운송계수를 결정하는데 TDR이 성공적으로 사용되고 있다. 본 연구는 TDR 기법이 사질 토양에서 중금속 이온의 운명과 시간에 따른 농도 분포를 측정하는데 적용가능한지를 알아보기 위하여 수행되었다 실험실에서 파과곡선 조건의 주상실험을 수행하여 사질토양에서 침출수와 잔존수의
