Abstract

A multi-layer scanning 3-D PIV system was developed, in which the different elevated laser light sheets (LLS) were projected into the tilting flume almost simultaneously. This specially designed PIV system is able to measure time-dependent velocity components in the 3-D region at the same time. In this study, turbulence measurements were conducted in a compound open-channel flow, in which large-scale horizontal eddies were observed near the junction region between the main-channel and floodplain, and as the results, it was found that there were large correlation properties between the different elevated layers and the tube-like horizontal eddies were transported in the downstream.
