Coherent structure of meandering flow with flood plain are investigated using a nobel visualization techniqe that utilizes fluorescent dye excited by a sheet of harogen light sheet and-black lamo.Some new aspects of reversional spiral flow, in corner region, especially with respect to pattern of existence, structure, behavoir and formation are inferd from the present experiment.Tne results indicate that a lot of various coherent structures are formed in turblent meandering flow with flood plain.The structures are characterized by some boundary conditions and main flow.
