IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Numerical investigation of flow and sediment transport around a circular bridge pier
Author : S. Abdelaziz1, M.D. Bui1, and P. Rutschmann1
A computation module for sediment transport in open channels was developed and incorporated into the commercial code FLOW-3D. In the module, the bed-load transport is simulated with a non-equilibrium model. Effects of bed slop and material sliding are also taken into account. The bed deformation is obtained from an overall mass-balance equation for sediment transport. This paper presents the results of a model application to compute the temporal variation of flow and scour around a circular bridge pier. The experimental investigation has been carried out by Unger and Hager (2006). The predictions are compared with measurements of flow and bed deformation, for which the results show generally good agreement.
