397399 - Numerical Simulation of Sediment Transport and Scouring around Hydraulic Structures on Rivers

Tuesday, June 5
4:00 PM - 5:30 PM
Location: Regency Room

After completion of the Four Major Rivers Restoration Project, several hydraulic structures have been built on main rivers in Korea. Consequently, sediment deposition and scour occurred around such hydraulic structures have become a critical issue. Following our previous study (V. T. Nguyen et al., 2015), in this study we continue to modify and apply an open source software package, the TELEMAC, to simulate sediment transport and scouring processes around hydraulic structures on rivers. Particularly, we have studied the effect of bed grain size distributions on bed evolutions, and taken into account the flood return periods to predict the maximum potential erosion around the hydraulic structures. Numerical results have been validated against available field observations, and an agreement between numerical result and observation shows the ability of the model to predict maximum scoured depths near hydraulic structures in order to suggest maintenance scenarios.
