토양유실 자동화 수집기를 통한 토양유실량 추정

The research of soil conservation, especially in agricultural slope field, was not an easy work because of the difficulty of the precise measurement of soil losses. This research aims at the real-time quantification of soil losses measurement. The automatic measurement tool of soil losses was plotted with water environment research equipment ISCO 6712 model attachable to ISCO 674 rain gauge and ISCO 730 bubbler flow module. Besides, to detect the suspended concentration of run-off water the sampling bottle was connected to each water level horizon in reservoir tank at 10 cm interval. Using our planned installations, soil losses content was detectable over time and the estimated soil loss quantity approached to the measured loss amount at the confident range of 85.1% and 101.7% in a storm of 161.3 ㎜ and 82.6 ㎜ rain of 2017 year.
