Discharge Method to Estimate the Flow in Asymmetric Compound Open Channel
During flood, the water from the main channel inundates the floodplain which is known as compound channels. Floodplains are at one or both sides of the main channel known as asymmetrical or symmetrical compound channel, respectively. Estimating the rate of flow in compound channel is an important factor in flood controlling projects. For estimating the rate of flow in compound channel, various traditional and modern methods have been discussed such as single-channel method (SCM), divided-channel method (DCM), Exchange Discharge Method (EDM), lateral distribution method (LDM), and Shiono–Knight method (SKM). Generally, these methods either have extensive computations or use numerical solution of differential equations. But, their efficiency for all compound channels with various hydraulic and geometric conditions may not be satisfied. In this study, the accuracy of the aforementioned methods has been compared for symmetric, asymmetric, and non-prismatic compound channels. Data are collected from the literatures from the present analysis. Error analysis has been performed to check the strength of different existing discharge estimation methods, and the best suitable method is recommended for the estimation of flow in compound channel.
