| Flow in meandering channel is a great concern to civil engineers and may further be characterized as one of the key problems in river morphology. It is difficult to state generalized criteria for channel improvement applicable to any particular river. But it is important to provide some principles and quidelines for the design engineer. The objective of this experimental study is to suggest riprap size, principles and quidelines for the design engineer by the hydraulic model test. For the sake of effective uses for the bank stabilization, hydraulic model tests about riprap weight and size are performed and examing thoroughly. Riprap weight for the upstream of the curvature appex can be computed by U.S.B.R. and Brahms' equation, and the size by Mavis and Laushey's equation. Those for the downstream can be computed using Brahms' and Steinberg's equations, respectively. |
