Abstract

Scouring is a natural phenomenon that often occurs in streams. Scouring can also occur locally if there are any changes in streams such as structural components within. A review of the literature has been accomplished to investigate the previous results of the effectiveness of riprap design. However, few studies were focused on the position of riprap layer design. Therefore, the main purpose of this study is to compare the effectiveness of riprap layer design for circular bridge pier by experimental study. Several scenarios have been set up by compared two layers conditions (the lower and upper sediment-based riprap layer design). The flow sediment condition used in this research is clear water condition. The stable riprap size and the optimized extension of the riprap layer around the circular pier along the flow direction were studied experimentally. The result indicates that the lower sediment-based riprap layer design is ±10 to 20% more effective compared to the upper sediment-based riprap layer design with different discharge flow scenarios. Further studies are also needed regarding the effect of riprap characteristics such as shape and diameter, variations of riprap thickness, and other related variables.
