Abstract

The government has recently carried out monitoring to attain a better understanding of the current situation and model for prediction of future events pertaining to water quality in the estuarine area of Yeongsan River. But many users have noted difficulties to understand and utilize the results because most monitoring and model data consist of figures and text. The aim of this study is to develop a GIS-based integrated information system to support the understanding of the current situation and prediction of future events about water quality in the estuarine area of Yeongsan River. To achieve this, a monitoring DB is assembled, a linkages model is defined, a GUI is composed, and the system development environment and system composition are defined. The monitoring data consisted of observation data from 2010 ~ 2012 in the estuarine area of Yeongsan River. The models used in the study are HSPF (Hydrological Simulation Program-Fortran) for simulation of the basin and EFDC (Environmental Fluid Dynamics Code) for simulation of the estuary and river. Ultimately, a GIS based system was presented for utilization and expression using monitoring and model data. The system supports prediction of the estuarine area ecological environment quantitatively and displays document type model simulation results in a map-based environment to enhance the user's spatial understanding. In future study, the system will be updated to include a decision making support system that is capable of handling estuary environment issues and support environmental assessment and development of related policies.

최근 정부에서는 영산강 하구역 수질환경의 현재 상황 파악 및 미래 상황 예측을 위하여 모니터링 및 모델 연구를 진행 중에 있다. 그러나 모니터링 및 모델 자료는 대부분 수치 및 문자 형태로 이루어져 있어 사용자들의 이해도가 떨어지는 실정이다. 따라서 본 연구에서는 하구역 수질환경의 현재 상황 파악 및 미래 상황 예측을 지원할 수 있는 GIS기반 통합정보시스템을 개발하였다. 시스템 개발을 지원하기 위하여 모니터링 및 모델 DB 수집, 모델 연계 방안 마련, 시스템 GUI 및 개발환경 정의, 시스템 구성 등을 수행하였다. 모니터링 자료는 2010 ~ 2012년 영산강 하구역을 대상으로 실시된 관측값을 사용하였으며, 모델 자료는 유역 지역을 모의하기 위한 HSPF(Hydrological Simulation Program-Fortran) 모델과 하천 및 하구 지역을 모의하기 위한 EFDC(Environmental Fluid Dynamics Code) 모델 자료를 사용하였다. 최종적으로 모니터링 및 모델 자료를 시스템에 적용하여 관리 및 표출 방안에 대하여 제시하였다. 본 연구를 통해 개발된 시스템은 영산강 하구역 수질환경을 정량적으로 파악 및 예측하는데 지원할 수 있으며, 지도 기반 환경에 모니터링 및 모델 자료를 표출함으로써 사용자의 공간적 이해도를 높였다. 향후에는 영산강 하구역 수질환경 문제점에 대처 가능한 의사결정지원시스템으로 고도화하여 환경 평가 및 정책 수립에 지원할 수 있을 것으로 기대된다.
