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.

Development of a numerical model for debris flow over steep slope terrain near the suburbs and urban area
In this study, a numerical model for the debris flow analysis was developed with emphasis on adopting the flow resistance
relations with among 10 bottom shear stresses in the literatureoptions. To these ends, the shallow water equations were
modified to have variable bottom shear stresses, and Petrov-Galerking stabilization scheme was employed to consider
complex geomorphology in the suburbs and urban areas. The Numerical results from the developed model in this study
was were compared with the analytical solution in applied to the dam break problem by plastic fluid. Since physical
phenomena of the debris flow were accurately reflected on the mathematical model, the developed debris analysis model
for general purposes was found to be efficient in simulating the debris movement and computing the extent of spread
