摘要

Vertical drop structures (weir, grade control, check dams) are often adopted for engineering approach to intake water or to deal with channel degradation problems in Taiwan. This study presents five failure cases of vertical drop structures in weak bedrock channel. Three types of failure processes of the drop structures were concluded according to the results of field investigation and aerial-photograph observation. These processes include (1) local scour in channel bed and bank toe downstream the vertical drop structure; (2) scour at structure edges of the transition interface between artificial material and natural bedrock; (3) damage of concrete pavement by impact of large boulders.
