Abstract

A profiling monitoring system has been developed to monitor the water quality variations according to each water depth and applied for a test-bed. The key parameters were derived to disclose the aquatic ecology and environment of river systems, and the real-time monitoring techniques to profile the variations of each parameter were verified. Monitoring parameters were configured to include water quality, hydrodynamic, and weather conditions. Considering the water depth of the 4 major rivers in Korea, a profiling monitoring system with 1.0 m water depth interval for each monitoring has been established. To understand the real-time variation properties in the Han river, the monitoring system has been installed and operated at the YangHwa-Dock as a test-bed. Based on the results of the detailed analyses on the spring season, as the characteristic diurnal and water-depth-related variations for water temperature, pH, dissolved oxygen (DO), and chlorophyll-a were observed, it could be concluded that the real-time water-depth profiling monitoring system is a very effective tool for the proper management of river environment.

수심에 따른 수질 변동을 모니터링할 수 있는 수심 프로파일 모니터링시스템을 개발하여 대하천의 현장에 적용하고자 하였다. 이를 위하여 하천의 수생태 및 수환경 변화를 반영할 수 있는 핵심 항목을 도출하고, 수심별 실시간 모니터링 기법 및 시스템을 개발하였다. 모니터링 항목은 수질, 유황 및 기상 항목을 포함하도록 구성하였다. 대하천의 수심을 고려하여 1.0 m 간격으로 모니터링이 가능한 시작품을 제작하고, 한강 수질의 실시간 수심별 변동특성을 파악하기 위하여 양화선착장을 test-bed 대상지로 선정하여 모니터링시스템을 구축 운영하였다. 춘계를 대상으로 상세분석을 실시한 결과, 수온, pH, 용존산소량(DO) 및 클로로필 a 등의 항목에서 뚜렷한 일주변화 및 수심별 변화가 관찰되어 수심별 실시간 모니터링이 하천 수환경의 적절한 관리를 위한 매우 유효한 수단인 것으로 나타났다.
