ABSTRACT

This experimental study discusses flow velocity around concrete wings for the reduction of scouring on bridge pillars. Therefore, this study aims to analyze the flow velocity around the bridge piers before and after the concrete flange curtain by using iRIC (International River Interface Cooperative) software Nays2HD 3.0. A soil channel model with trapezoidal cross-section, cylindrical pillar and concrete wing curtain model was used in this study. The observation objects were flow discharge (Q), flow velocity (v), flow depth (h), and scour depth elevation (ds) in each time interval. Furthermore, the simulation results showed that the lowest and the highest flow velocity were 0.000 m/s and 0.998 m/s, respectively. The flow velocity that occurred around the bridge piers and concrete wings was relatively small due to the changing direction of flow after the concrete wings. Meanwhile, the scour that occurred around the bridge pillars was relatively small due to the presence of concrete wings in front of the pillars. Based on the validation results between the analysis of the iRIC software, Nays2DH 3.0 and a physical model at the output velocity (ms-1), there was an insignificant difference of 4.61%.
