Effects of cylindric al foundation on bridge pier scour / Hazmiah Mohammad Saibi

An experiment investigation at local scour at non-uniform cylindrical pier. A non-uniform pier is one of which the cross-sectional dimension varies over the length of the pier. The pier comprise a cylinder of diameter, D founded on a largest cylinder of diameter, D* cal! the foundation. The project aims to make a comparison on the estimation of local scour depth at foundation on bridge pier by using a data that observed from an experiment and the design method. Test were carried out on the models cylindrical foundation on bridge pier using wave flume situated at the hydraulics Laboratory department of Civil Engineering Mara Instrtute of Technology, Shah Alam, Selangor, Malaysia. A data taken inctuding a depth of scour, width of scour, discharge and depth of flow. A design method applies to determine an equilibrium scour depth.
