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.

An efficient hydrodynamic modelling system for predicting flood induced geomorphological processes
Author : QIUHUA LIANG(1,2), JINGMING HOU(2), LUKE S SMITH(2)
ABSTRACT
This work presents a 2D hydro-morphological modelling system within the framework of a Godunov-type finite volume scheme for simulating hydro-morphological processes under flood conditions. The model solves the 2D shallow water equations for flow hydrodynamics and includes a coupled component for geomorphological evolution that takes into account the transport rate and capacity of both bed and suspended load. The coupled modelling system is implemented on graphics processing units (GPU) to substantially improve the computational efficiency for practical applications. The performance of the new hydro-morphological modelling system is demonstrated by reproducing a laboratory test and then applying it to simulate the hydro-geomorphological processes during a field-scale flood event.
