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.

A novel well-balanced scheme for modelling of dam break flow in drying-wetting areas
Author : JIA MAO(1), LANHAO ZHAO (2)
A novel well-balanced finite element scheme is proposed for simulation of dam break flows over complex domains
involving wetting and drying. The shallow water equations are discretized by a fractional finite element method using a
two-step Taylor-Galerkin scheme. In order to maintain the ‘well-balanced’ property, the pressure gradient term and bed
slope terms are incorporated into the Poisson equation, and a local bed slope modification technique is employed in
drying-wetting interface treatments. The new model is validated against several benchmark tests and laboratory
experimental data related to dam-break flood wave propagation and promising results are obtained.
