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.

Shallow Water Flow Simulation Using Multislope MUSCL Method
Author : Jingming Hou, Qiuhua Liang, Franz Simons and Reinhard Hinkelmann
Based on the classical multislope MUSCL method, this paper develops a new multislope MUSCL method which is used to extrapolate the values of the variables at the midpoints of the cell edges. This method is in a more straightforward form than the classical one. By using the extrapolated values to compute flux and slope source terms, this method is incorporated into a 2D unstructured cell-centered Godunov-type finite volume shallow water model. The good performance of the 2D shallow flow model with the new multislope MUSCL method is demonstrated in three test cases including both theoretical and practical ones. It is verified that the new method is more efficient than the classical one and is able to produce better or similar results. Moreover, the new method can be applied to simulate real large scale cases.
