Abstract

The withdrawal method for protecting the uncontaminated part from the spread of contaminants was suggested by a simultaneous equation. The formulation of them is based upon the build up of the ridge part between the contaminated and uncontaminated parts that resulted from the efficient use of barrier wells. The quality in the withdrawn groundwater depends upon the heads at wells no. 5 and 6. The determination of pumping rates and qualities with changing the heads at wells no. 5 and 6 should be given by considering the demand for water use and the capacity and cost for removing the contained contaminants. The results of this study should be used in taking a plan for supplying water use as well as preventing the spread of contaminants from some known contaminated sources.

비오염양분(非汚染郞分)에로의 오염물질(汚染物質)의 확산(擴散)을 방지(防止)하기위한 격수방법(格水方法)이 하나의 연립방정식(連立方程式)으로 구해졌다. 입식(立式)에 있어서 기본개념(基本槪念)은 오염부분과 비오염부분의 사이에 주변보다 높은 수위를 가지는 고수위(高水位)부분을 형성하는 것이며, 이 부분의 형성은 항해(降害)우물의 유효이용으로 이루어졌다. 양수된 지하수의 수질(水質)은 우물 5와 6의 수위(水位)에 따라서 결정되었다 우물 5와 6의 수위변화에 따른 양수속도(楊水速度)와 수질의 결정은 용수(用水)의 수요(需要) 및 함유된 오염물질의 제거(除去)능력과 그에 따른 실용(實用)을 고려함에 의해서 주어질 수 있다. 본 연구의 결과는 기지(旣知)의 오염원(汚染源)으로부터의 오염물질의 확산을 방지하는 것 뿐만아니라. 용수공급을 위한 계획의 수립에도 이용될 수 있을 것이다.
