Abstract

Monitoring of river is significant both in flow management and river usage. Although river monitoring systems have been installed in many rivers in Japan, most of the existing system do not record images and utilize them for quantitative measurement of the flow. Already proposed methods for quantitative measurement include image analysis techniques such as large scale particle image velocimetry (LSPIV) or space-time image velocimetry (STIV) proposed by the authors. However, there still resides skepticism about the accuracy of the methods. Therefore, we conducted concurrent measurements with ADCP to verify the performance of the image analysis techniques. At the same time, we established a quasi-real time system of discharge measurement by introducing a novel image collection system with high image compressibility.
