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.

Flow Process of the Embankment Breaching
Author : Gensheng Zhao, Yankai Ren, Paul J. Visser and Wim S.J. Uijttewaal
Dam-breach usually happens as a result of extreme floods, earthquakes, stability drawbacks, etc., which threatens human being downstream the dam and causes costly losses. In the flood management, the dam-breaching flow plays a great role in the dam-breaching process. The paper discusses the complex hydraulic characteristics of breaching flow and gives the simulation via the physical model and numerical model. The physical model is set up to analyze and verify the hydraulic factors of the breach. The 2-D and 3-D model are used to simulate the breaching flow over the dam. The distributions of velocity, Froude number are discussed for the breaching flow. The study results of the physical and numerical simulation provide the foundation for the breaching process and are of great value to the flood management referring to the dam-breach, including the flood propagation and river erosion induced by the breach.
