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.

Cfd simulation of local scour in complex piers under tidal flow
Author : J. A. Vasquez, and B. W. Walsh
We report the qualitative simulations of local scour in complex bridge piers under tidal flow using the commercial Computational Fluid Dynamics (CFD) model Flow-3D. The model was applied to compute the initial stages of scour development in a complex pier made of a large pile cap and 10 cylindrical piles. Flow-3D was able to correctly reproduce the expected interaction between the piles. The CFD model was also applied to simulate scour in a 3-pile group under tidal flow reversal. The results were in qualitative agreement with measurements reported in the literature, demonstrating that Flow-3D has potential as a hydraulic design tool for complex piers under various flow conditions.
