Oblong Bridge Pier Shape Influence toward Flow Velocity Characteristic and Scour Depth

Flows that occur in rivers are usually accompanied by scouring/erosion and sedimentation/deposition processes. The scouring process that occurs can be caused by river morphological conditions and the existence of river structures that obstruct the flow. Structures such as bridge piers can change flow patterns so that in general can cause local scouring. One method for reducing the scouring that occurs around a bridge pier is to consider the shape of the pier bridge design. One of the most common pier bridge designs is the oblong shape. This research aims to find out the effect of streamlining the oblong pier shape on the change in flow characteristic and scour depth reduction using FLOW-3D numerical modeling. © Published under licence by IOP Publishing Ltd.
