Abstract

Streams have an important function for human by providing irrigation, electricity, etc. Streams also have the sediments within that typically flow following the direction of water velocity. The differences in characteristics among streams have also been clear since it can be changed easily due to climate change, or other natural factors. Streams also can change in dimension according to the surrounded environmental conditions, for example local scouring caused by bridge pier. And then by using riprap is the most common countermeasure to prevent local scouring. Riprap is a method that can be used to prevent erosion in streams or other conditions that have water flows with high velocity. Therefore, the purpose of this study is to compare two models riprap design around the pier for scour protection. The riprap models that were compared are rectangular and circle shaped. The condition used in this study is clear water condition, under sediment-based layer design, and riprap layer thickness. The experimental study was used to compare both riprap model design. The result of this study indicates that circle shape model riprap is better than a rectangular shape. Further studies are necessary regarding the effect of flow type, cross-sectional shape, or other related variables.
