“…Similar phenomena were also observed by Odgaard and Bergs [21]. Using experimental data of a rectangular fixed-bed river bend, Hussein and Smith [10] suggested the following modified logarithmic law profile to reflect the downward shift of the location of the maximum velocity.…”

“…(4)), is a function of the width-depth ratio. The width-depth ratio of this experiment was about 10 and according to the data of Hussein and Smith [10], the corresponding a value was proposed to be 0.2. At the channel centerline, the velocity profile is similar to that of a straight channel, and hence a equals to zero.…”

“…In this study, the concept proposed by Hussein and Smith [10] is extended for alluvial channel bend. Combining the velocity profile and the longitudinal depthaveraged momentum equation, satisfactory solution for the depth-averaged mean velocity distributions at the alluvial channel bend is obtained.…”

The existence of the secondary current changes the vertical and lateral velocity distributions, bed topography, and sediment gradations in an alluvial channel bend. An analytical solution is proposed to describe the transverse bed slope, lateral depth-averaged mean velocity distributions and sediment distributions for both developing and fully-developed reaches of an alluvial channel bend under steady uniform flow conditions. The theory is based on the findings of Odgaard [20] and Hussein and Smith [10], coupled with a streamwise momentum equation, and a longitudinal force balance equation. The results are verified by experimental data of Lee [15] and Odgaard and Bergs [21], and by field data of Sacramento River [22]. The solutions obtained are quite accurate. -ê-JOdgaard [20] • Hussein and [io] z m m ftes Lee [15] R Odgaard and Bergs [21] Zií^ftÍtA Sacramento * Correspondence addressee Downloaded by [Purdue University]
