GERUSAN DI SEKITAR PILAR JEMBATAN PALU I SUNGAI PALU
Abstract
The purpose of this research is to know scour around Palu I bridge pier. The benefit of this research is as one ofthe material for evaluation of scour around the bridge pier. The method used in this research is simulation using HECRAS(Hydrologic Engineering Center-River Analysis System) software. This simulation is done with river topographyand geometric bridge as geometric input, average discharge as upstream input and bed slope as downstream input andbed sediment as input grain. Based on simulation result and Analysis of bridge scour HEC-RAS at january discharge(lowest) Q = 63.977 m3 / sec maximum scour depth at 1.30 m and at May discharge (highest) Q = 204.004 m3 / secmaximum scour depth of 1,67 m.References
