GERUSAN DI SEKITAR PILAR JEMBATAN PALU I SUNGAI PALU
Abstract
the 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 topography
and geometric bridge as geometric input, average discharge as upstream input and bed slope as downstream input and
bed 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 / sec
maximum scour depth of 1,67 m.
