Abstract

The river is a place where scouring events occur continuously based on the flow in the river itself. In this research model aims to analyze the distribution of flow patterns using triangular plate resistance. Installation of this barrier is to prevent scouring to the bottom of the channel as a result of scouring in the bridge abutment structure that is experiencing structural failure.This research was conducted using the Nays2DH computational simulation from I-ric with flume modeling. In flume modeling, the flow pattern that occurs after passing through the plate resistance makes a certain pattern so that the scour that occurs can be predicted. It is expected that these results indicate the flow pattern that occurs after the resistance has changed. Flow pattern is very influenced by discharge, channel cross section, flow velocity, shields number and shear stress.
