Abstract

Recently, along with the increase in chemical accidents, the number of accidents-related disasters has been increasing continuously since 2012, and when looking at the hydrogen fluoride incident which is a representative example of domestic chemical incidents, there is insufficient technology applicable to the incident site. The result was that the damage spread. Therefore, in this paper, we will adapt the water pollution accident response system to a location-based approach, and introduce a measurement method for alternative index tracking using a GPS electronic floater of a location-based index measurement method for real-time response in the water environment when a chemical incident occurs. The research target area is Gumi City, which is the area where the hydrogen fluoride incident occurred, and Gamcheon is selected, and alternative tracking using GPS electronic floater is conducted in the corresponding target area through water quality and flow measurement. As a result, it is possible to measure water quality and flow at the same time in tracker experiments using GPS electronic floater based on the research results, it is believed that using GPS electronic floater will be of great help in disaster response systems for spill incidents in the river.

최근 화학사고 증가와 함께 사고로 인한 재해에 대한 건수가 2012년부터 계속적으로 증가하고 있으며 국내 화학물질 사고 대표 사례인 구미 불산 사고를 보았을 때, 사고현장에 적용 가능한 기술이 미흡하여 피해가 확산되었다는 결과가 발생하였다. 따라서 본 논문에서 수질오염사고 대응체계를 위치기반에 맞춰 화학사고 발생 시 수환경에서 실시간 대응을 위한 위치기반의 지표측정방식의 GPS전자부자를 이용한 대체지표 추적에 대한 측정방법과 그에 대한 연구결과를 소개하고자 한다. 연구대상지는 불산사고가 발생했었던 지역인 구미시를 대상으로 김천시와 구미시 등 2개 시 로 이루어진 감천을 선정하였고 해당 대상지에 수질-수리 측정을 통해 GPS전자부자를 이용한 대체추적물질 추적에 대한 실험을 진행하였다. 이를 통해 GPS전자부자를 이용한 추적자실험에 있어 수질-수리 측정이 동시에 가능하며, 특히 해당 연구결과를 통해 GPS 전자부자를 활용한다면 하천 분야에서의 유출사고에 대한 재난대응체계에 상당히 도움이 될 것으로 사료된다.
