Abstract

The large breeding of algae in rivers has caused the algal bloom and has becoming a serious national problem for the safety of water sources. Therefore, in order to supply stable water resources through securing clean water, it is necessary to develop technology for prevention of water pollution caused by algal bloom. The purpose of this study is to improve the water quality management ability of river by applying the algal bloom detection technique using UAV. Unmanned aerial images were acquired for the Dodong in the middle region of the Nakdong River where algal bloom are frequent. In addition, the phytoplankton concentration was acquired through the sampling of algal bloom and the examination of water quality. Correlation between phytoplankton concentrations and the results of applying the algal bloom index to the Unmanned aerial images showed a strong positive correlation. The remote sensing method suggested in this study is expected to improve the initial response capability of river water pollution.

하천에서 조류의 대량 번식은 녹조를 일으키고 수자원 안전에 대한 심각한 국가적 문제로 제기되고 있다. 따라서 깨끗한 용수를 확보하여 안정적인 수자원 공급을 위해 녹조로 인한 수질오염의 방재 기술 개발이 필요하다. 이에 본 연구는 무인항공기를 이용한 녹조 모니터링 기법을 적용하여 하천의 수질 관리 능력을 향상 시키고자 하였다. 녹조현상이 빈번하게 발생하는 낙동강 중류의 도동 나루터를 대상으로 무인항공영상을 취득하였다. 또한 녹조시료 채취 및 수질검사를 통해 식물성 플랑크톤의 현존량을 조사하였다. 무인항공영상에 녹조 탐지 지수식을 적용한 결과와 식물성 플랑크톤의 현존량 간의 상관관계가 강한 양의 관계를 가지는 것으로 나타났다. 본 연구에서 제안된 원격탐사 기술은 하천 수질 오염 초기 대응 능력을 향상시킬 것으로 기대된다.
