MEASUREMENT OF DIFFERENCES IN FLOW VELOCITY DISTRIBUTION BETWEEN WITH BED LOAD AND WITH SUSPENDED LOAD

Abstract

 Many experimental studies about sediment transport have been carried out until 1990's. These days, research with numerical simulation for bed changing have been taken with knowledge from experimental research results. However, there are some issues of estimation of sediment transport rate. Advanced measurement technologies, camera and PIV system, and so on enable measurement of flow distribution with sediment flow to be carried out. Therefore, some series of flume experiments have been taken in order to indicate relationships between sediment movement and water flow strictures with PIV and PTV system. I could measure sediment particle velocity and flow velocity with PIV/PTV, so that I succeeded in indicating effects of both suspended load and bed load transport on flow velocity.
