This study develops a GIS-based system which examines the adequacy of the Groundwater development project before the actual designing of the project. Using the system developed here, we can transfer simulation results obtained by WHPA regarding Groundwater levels in new development projects into GIS. We can also judge whether a Groundwater development project should be permitted through examining overlaps of the effects of the development and comparing with other pollutants. Since a two-tiered system which shares DB using inter- and intranets is developed, all the departments in the ministry of agriculture and forest and the agriculture base corporation can share accurate, reliable and latest information related to Groundwater.

본 연구에서는 WHPAs와 GIS 프로그램을 이용하여, 지하댐 건설 후 지하수를 효율적이고 안정적으로 양수하기 위해 관정 설치위치를 선정하고, 양수 시 영향반경을 예측하였다. A관정의 지하수 유동방향은 북서방향이고, B관정은 남쪽방향 그리고 C관정은 남서방향이다. 세 개의 관정(A, B, C)에 대하여 양수시 지하수 영향반경 해석을 수행하였다. A관정은 지하수 유동방향이 하천을 향하고 있어 하천의 영향이 적기 때문에 양수 시간에 따른 지하수 영향반경이 크게 차이가 나타난 반면에, B관정과 C관정은 주변의 지하수 유동방향과 하천의 영향으로 양수 시간이 늘어나도 지하수위 영향반경의 면적에 큰 변화가 없는 것으로 나타났다.

This study develops a GIS-based system which examines the adequacy of the Groundwater development project before the actual designing of the project. A system environment is constructed in order to efficiently and scientifically manage and analyze data related to Groundwater through a Server/Client environment. For this programs such as GIS S/W ArcVies3.2, RDBMS ORACLE, ArcSDE (Spatial Database Engine) are used. WHPA and AQTESOLV are employed as a underground water simulation program and Scripts, a language for ArcView, is used to develop graphic user interface (GUI). Using the system developed here, we can transfer simulation results obtained by WHPA regarding Groundwater levels in new development projects into GIS. We can also judge whether a Groundwater development project should be permitted through examining overlaps of th effects of the development and comparing with o pollutants. At the same time, the system has a feature of supporting Groundwater development and based designing through judging the proper amount of Groundwater in a new project. It is also possible to easily and quickly prepare charts and reports using the outputs of the system. Since a two-tiered system which shares DB using inter-and intranets is developed, all the departments in the ministry of agriculture and forest and the agriculture base corporation can share accurate, reliable and latest information related to Groundwater.

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.
