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 lattice boltzmann model for one-dimensional open channel flow
Author : HONGDA WANG(1), HAIFEI LIU(2)
ABSTRACT
A new lattice Boltzmann approach to the one-dimensional open channel flow is developed by solving the Saint-Venant
equations. Contrary to the conventional computational fluid dynamic method, the lattice Boltzmann method is based on
reallocating the computational particles on lattice spacing, by choosing corresponding equilibrium distribution function
properly. The model is verified by two benchmark tests, a one-dimensional subcritical gradient flow and a dam-break
wave flow. The results showed the accuracy of the proposed method and its good applicability in simulating open
channel flow.
