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.

Numerical modeling of the tidal bore propagation process
Author : WEI WU(1), DONGFANG LIANG2)
ABSTRACT
A tidal bore is an integral part of our environment and cultural heritage. It is a series of waves propagating upstream with a
sudden increase in flow depth that may form during spring conditions when the tidal range exceeds 4-6m. This paper
concentrates on numerical modeling of the tidal bore propagation process. A hybrid of the two-dimensional Boussinesqtype
model and the shallow water model are applied to simulate this natural wonder, which is solved using a shockcapturing
TVD (Total Variation Diminishing) Lax-Wendroff scheme. Severn River bore is one of the most famous fluvial
landmarks in Europe. This paper emphasizes on the propagation process of Severn River bore. The numerical results are
validated by some existing experimental measurement data. Then the influence of some hydrodynamic parameters on the
Severn River propagation process is studied. Parameters include the river flow rate, the bed friction and the development
of tidal energy project in the Severn River estuary, which remains to be a controversy since it was put forward. The future
results can provide people with a more comprehensive view on how to better protect the tidal bore and ecosystem.
