Abstract

The Suramadu Bridge is the longest bridge in Indonesia, located at Madura Strait causes an increase in the speed of ocean currents as well as obstacles to seawater flow acceleration of ocean currents due to the reduce of the wet cross-sectional area of seawater flow. This influence cause changes in the seabed bathymetry along the Suramadu Bridge and the potential for local scouring on the bridge foundation. In dangerous stage of scouring, can affect the stability and carrying capacity of the foundation structure under the bridge. The Suramadu Bridge has operated since 2009, has been almost 10 years, and bathymetric surveys is needed to ensure the actual conditions on the seabed under the Bridge. The purpose of the bathymetric survey activity is to obtain the latest bathymetric data and the scouring patterns arround the main pillar (P46 and P47) of the Suramadu Bridge. The Bathymetric Survey method used are SBES and MBES. The first Bathymetric survey was obtained at the year of 2016 since the bridge had operated, shows that the scouring was indicated at the main pillar the increase is about 7 – 8 m. Based on the bathimetric survey data of the 2017, shows the scouring is increased is about 1 meter below the result of bathymetric survey of 2016 at the seabed in the main bridge.
