| Research Abstract |
The viewpoint of the relationship between alternate bars formation and intake weir is very important to improve the planning and design of diversion dam. Analysis by field survey and flume experiment on four problems, (1) the mechanism of river-bed scouring downstream of a weir and the effect of downstream bed protection works to prevent disaster suffering, (2) the destruction of upstream bed protection works, (3) problems of sand accumulation and river bed scouring around a complex-type weir, and (4) the possibility of disaster suffering of fish ladder which stretches to upstream reach, showed the superiority of the weir with good relation to bar shape and proper structure of bed protection works to deduce bed scouring downstream of a weir.
