STUDY ON MOVING CHARACTERISTIC OF FLY ASH BEADS BY THE FLOW AND WAVE

Abstract

 Fly ash beads has been utilized for sludge to the enclosed bay as a beach sand alternate material and the water improvement effect is obserbed. In order to design the shoal by fly ash beads, it is necessary to understand the moving characteristic of the fly ash beads by flow and waves. However, the detailed moving characteristic in the shoal is not clear. So the moving characteristic at the time of installing fly ash beads in a shoal is clarified by a hydraulic model experiment. This paper reports the experimental result about moving characteristic of fly ash beads by the flow and wave.
