On the Image Processing of the Alluvial Channel Bed Configuration During Its Initial Formation and Development Stages

Abstract

A non-contact and simple method of quantitative measurement of alluvial channel bed configuration during its initial formation and development stages under running water has been devised. The information of the bed configuration obtained by the use of a laser-light sheet and ultra-sonic sounder is undergone the image processing by the use of an electronic computer. The time-and spatial variations of the bed configuration can thereby be obtained with no interruption of water flow.
