Abstract
Meandering bed pattern with alternate scour holes, which occurs occasionally in rivers, was reproduced consistently in a straight laboratory flume. The occurrence of this pattern was directly related to: (1) The presence of rough walls, and (2) the increase of main flow velocity with both time and distance. This study clearly pointed out the importance of investigation on unsteady and nonuniform flows for the understanding of river morphology.
