碩士 / 國立成功大學 / 水利及海洋工程學系碩博士班 / 93 / This paper mainly inquire about Cheng Kung Artificial Waterweeds (CKAW) as a pier scour countermeasure in a free overfall. From the experiment and the results, we know that the effect of diversion was not effectively improved by using CKAW individually in free overfall condition. It indicated that the effect of local pier scour protection is better than total scour protection. However, the efficiency of total protection was improve more than 43.5% by using CKAW with support bar. Furthermore, the effect of pier scour protection in bridges was also investigated by changing length of CKAW. The results showed that length of the CKAW was not related to the effect of pier scour protection.
