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.

Modeling dam break flows using sph technique
Author : H.M. Kao, C.H. Wang, T.J. Chang, M.H. Hsu and Y.C. Tan
A meshless numerical model is proposed to investigate shallow-water dam break flows in 1D open channels. The numerical model is to solve the shallow water equations (SWE) based on smoothed particle hydrodynamics (SPH). The concept of slice water particle (SWP) is adopted in the 1D SPH-SWE formulations. Model validation is examined by a benchmark problem of dam break flows through a rough flat channel. The simulated results indicate that accurate performance is reached in the presence of shock discontinuities and shock front motion. The simulation is carried out by PC within 10 minutes. Thus, the proposed numerical model has proved its efficiency and reliability for dam break flow computations in open channels
