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.

Sph modeling of extreme hydrodynamic forces on slender structures
Author : P. St-Germain, I. Nistor, D. Palermo, R. Townsend
A three-dimensional Smoothed Particle Hydrodynamics (SPH) numerical model was used to simulate high-velocity bore impacts on structures that can occur during extreme events such as tsunamis, torrential flash floods and dam-break floods. Numerical simulations of the impact of hydraulic bores of varying heights on a slender circular structure are performed. Resulting forces, along with the time-dependent pressure distributions are compared with large-scale experimental results obtained by the authors as part of a comprehensive experimental program conducted jointly with the Canadian Hydraulic Centre at the National Research Council, Canada. This study is a component of a wider scope joint hydraulic and structural engineering research project, whose final purpose is to improve design guidelines for inland structures located in coastal regions prone to tsunami waves attack. The results of this study are also applicable to other types of extreme hydrodynamic impacts and loading such as flash floods and dam-break waves.
