非接触計測と水理解析による河川水位・流量 観測システムの確立に向けた検討

抄録

This study is to present a new safe and stable monitoring system for river water level and discharge by cooperation of image processing and hydraulic analysis. The authors individually developed subsystems such as (1) CCTV camera control, (2) water surface detection algorithm, (3) STIV and (4) DIEX method, and these were integrated. To confirm the fundamental performance of the present monitoring system, the prototype system has installed into the Ongagawa River, and laboratory experiments have also conducted. The results indicated that the evaluated velocity and discharge give good agreement with the observed data. Furthermore, we proposed a method for rejecting outlier.
