A UTILIZATION OF ADVANCED RIVER-DISCHARGE MEASUREMENT USING A CCTV OR A FAR-INFRARED CAMERA

Abstract

Space-time image velocimetry (STIV) is a promising tool for river-discharge monitoring, from the viewpoint of reliability and accuracy. Closed-circuit television (CCTV) cameras have been installed in high position along the rivers. Therefore, we tried to build a river-discharge monitoring system with high reliability and accuracy, by combination with CCTV camera and STIV. The results indicate that 59 units of CCTV cameras can be used for river-discharge monitoring in Kyushu region. In addition, present systems are automatic, continuous and give good agreements with the observed data using floats.
