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.

Use of Two Dimensional Hydraulic Models to Estimate Hydraulic Hazard
Author : Monique Retallick, Mark Babister and James E Ball
Hydraulic hazard (measured as the depth x velocity product) is used in floodplain risk management studies to identify flowpaths and floodways and suitable landuse. Hazard is used to define where people will be swept away, cars will be washed away and development should be excluded. Recent work by Cox et al. (2010) has revised the safe hazard values. It is therefore fitting to review the 2D models used to determine the hazard within rural and urban floodplains throughout Australia. This study builds on the work by Retallick and Babister (2008) and Werner and Lambert (2007) comparing existing data from physical models and theoretical results to 2D model results. Flow within the compound channel has chosen to produce an interesting hazard distribution on the overbank. The ratio of over estimation and underestimation was examined. The outcomes demonstrate the ability of the various software modelling packages used to estimate hazard.
