Velocity Distribution at the Cross-Over of Sinusoidal Trapezoidal Meandering Channels

Abstract

Evaluation of velocity distribution process longitudinally is very much essential for the environmental management, quantifying the mean velocity. In nature, most rivers tend to be of compound sections as well as meandering [1]. Velocity distribution is crucial for solving many engineering problems such as management of rivers and floodplains, it is important to understand the behaviours of flows within compound channels for designing of hydraulic structure, flood control, water management, sedimentation and excavation. During flood runoff water comes out natural or man-made channel, part of the discharge is carried out by simple main channel rest are carried out by flood plain. Experiment results are presented here for the studies conducted in two self designed channels, developed by known discharge. These data’s were used for the analysis of velocity distribution and depth average. Velocity at the cross-over of a meandering channel of different sinuosity at various flow depth where investigated for monitoring the contour mapping of flow and graphical analysis of velocity at the cross-over.
