Abstract

Groundwater simulation model suing GIS and Arc/Info Gridfunctions were used to delineate wellhead protection areas. Groundwater simulation model was developed within Arcview GIS. The model. which integrates the data input and manipulation. Process simulation. and display of the results . was developed by considering time variations of the parameters. The model was applied to the EPA data. The hydraulic distributions from the EPA data and those calculated from groundwater simulation model agree well and zone of influence from EPA data and that calculated suing GRID functions seem to be consistent. The developed model may be an efficient tool to delineate WHPA because it integrates all the processes inside the GIS.

우물수원의 보호구역의 범위를 결정하기 위해서 GIS를 이용한 지하수 모의모형ㅇ과 Arc/Info의 Grid 함수를 이용하였다. GIS를 이용한 지하수 모형은 Arcview GIS를 사용하여 모형의 시간변화를 고려하고 자료의 입력 및 조작, 모의, 결과의 표시 등을 GIS내에 통합한 모형으로 개발하였다. 모형을 적용하기 위해 미국환경의 자료를 사용하였으며 적용시킨 결과 지하수 모형에서 계산된 수두 분포와 우물의 영향권을 계산한 값이 본 논문에서 계산한 값과 거의 비슷한 값을 나타내어 모형의 타당성을 검증하였다. 본 모형은 GIS내에서 모든 처리가 이루어지므로 우물수원의 보호구역의 범위를 설정하는데 효율적인 방법이 될수 있을 것이다.
