Abstract: Unsteady flow characteristics were investigated experimentally recording detailed velocity measurements at three sections in a compound channel during repeated passages of a hydrograph. Extensive water depths measurements were recorded at eleven sections from upstream to downstream. Water depth variations, velocity distributions, discharge variations are presented. Flow depth and water surface slopes in the main channel and the flood plain are different to each other and it strongly effects on the flow mechanism. Flood flow propagation is also discussed.
