Abstract

This research aims to find The maximum scour depth occurred in building bridges using HEC -
RAS software . Maximum scour modeling results can be used to identify and estimate the
stability of the structure of the bridge. This research using software HEC-RAS v. 4.1.0. Stages
of modeling programming includes several data input process, that is: the geometry data input
stream, bridge geometry data input, input the data flow, data input on bridge scour. Modeling is
done with the flow rate changes on any one process is running. Modelling maximum scour who
reviewed that is on the pillars of the bridge. This research result of this modeling with the flow
rate variation, it can be seen that the discharge 5.87 m³ / s to 905.23 m³ / s began to increase
the depth of scour at the pillars. Then on debit 905.23 m³ / s to 1080.15 m³ / s scour depth
experience stability pillar, at a depth of 1.76 m.
