Abstract: Bridge scour is a severe and risk problem that costs millions of dollars of damage, leaves infrastructure such as bridge piers in unsafe conditions requiring maintenance, and occasionally results in loss of life. This paper summarizes the results of an experimental study on the countermeasure of scour below and bridge pier in currents. And this study analyzes factors affecting local scour in order to understand various characteristics of the local scour surrounding bridge piers. Attached with scour countermeasure devices as a method for decreasing local scour, it carries out the laboratory experiments and calculates the scour depth. From the experiments attached with the devices, it seems possible to reduce the scour depth. The paper presents the following research results: the scour depth increases in order of protecting column, protecting plate, sacrificial piles and non-protecting facilities
