Modelling the depth-averaged velocity in trapezoidal meandering channels
This paper presents a practical method to predict lateral depth-averaged velocity distribution in trapezoidal meandering channels. Flow structure in meandering channels is more complex than straight channels due to three-dimentional nature of flow. Continuous variation of channel geometry along the flow path associated with secondary currents makes the depth-averaged velocity computation difficult. Design methods based on straight-wide channels incorporate large errors while estimating discharge in meandering channel. Hence, based on the present experimental results, a non-linear form of equation involving three parameters for estimating lateral depth-averaged velocity is formulated. The present experimental meandering channel is wide (aspect ratio = b/h > 5) and with high sinuosity of 2.04. The study serves for a better understanding of the flow and velocity patterns in trapezoidal meandering channel.
