Development of Colored sand Analysis system for High Frequency Monitoring of Sediment Movement

Abstract

The prototype of colored sand analysis system, which uses high-speed and high-precision colored sand measurement and is based on a high-speed image analysis, was developed for sediment dynamics monitoring. Its reliability and usefulness were verified by introducing to the developed system, a new method of density measurement of colored sand by color discrimination method. By using this system, it has become possible to observe sediment dynamics on a high-frequency, short-term basis. As the investigation of coastal erosion and other phenomena progresses rapidly, it has been confirmed that the system provides practical techniques for sediment flux management.
