Discussion on 'Estimating depth-averaged velocities in rough channels'

In this short communication the four estimate criteria of the depth‐averaged local velocity proposed by Byrd et al. (Earth Surface Processes and Landforms, 2000, Vol. 25, pp. 167–173) are compared both with the three‐point method of Bathurst and with the average velocity obtained by integrating the...

Description
Summary:In this short communication the four estimate criteria of the depth‐averaged local velocity proposed by Byrd et al. (Earth Surface Processes and Landforms, 2000, Vol. 25, pp. 167–173) are compared both with the three‐point method of Bathurst and with the average velocity obtained by integrating the velocity profile (FPa2) suggested by Ferro and Pecoraro (Water Resources Research, 2000, Vol. 36, pp. 2761–2770). The comparison was carried out using 84 velocity profiles measured by an acoustic Doppler velocimeter in a rectangular flume with a gravel bed. Copyright © 2002 John Wiley & Sons, Ltd.
