River is one of the most important components in water resources for human and has important role in human civilization. Especially in Indonesia, river cannot be separated from its people’s life. In its development, river can be a meander. Meander has particular characteristic, which is the development of erosion in the outer side of river bend, and sedimentation in the inner side of river bend. <br /> <br /> <br /> This research aimed to study the effects of placement of bridge pier on a river bend to the local scour. The research conducted by building physical model on a flume in laboratory. Three pier models arranged from group pile was being used at three observation location that has been decided. <br /> <br /> <br /> Physical parameter results obtained from this research are velocity and scouring depth. Scouring depth obtained with visual observation on local scouring around pier with 30 minutes interval, and ended with topographic measure on the end of the research. Observed scour depth was then compared with estimation result from Colorado State University (CSU) <br /> <br /> <br /> equation. Result of the study shows that there is influence of the placement position of the pier in the river bend to the development of local scour, and local scour that developed in the river bend is deeper than the one developed in a straight channel. <br /> <br /> <br /> The influences of the placement of pier made into position factor on the river bend. These values added into Colorado State University as correction factor on the river bend.
