Abstract |
The effects of channel meandering and of width of sinuous streams on the sediment loads and the friction factors of the flows were studied in flume experiments. Thirteen triplets of experiments were conducted in the subcritical flow domain in one straight and two meandering laboratory channels with sand beds and rigid walls. In each run, measurements were made of water-surface profiles, bed elevations, and total sediment discharge. In addition, detailed measurements of the distributions of the magnitude and direction of the local velocity and of suspended sediment concentration were made in two of the meandering-channel experiments. |
