Abstract
In this paper, the problem of dam-break flood wave propagation in non-
prismatic channels has been analyzed. The aim was to verify if the De Saint
Venant one-dimensional equations expressed in the divergent form and
numerically integrated with the TVD-MacCormack scheme were suitable for
the description of the phenomenon. The computational scheme was employed
for the simulation of some dam-break laboratory tests in channel transitions
reported in the literature.
1 Introduction
The current trend in computational hydraulics is to resort to computational
schemes able to treat very accurately both gradually varied and rapidly
varied flows. They can be applied to unsteady open channel flow equations
expressed in the conservative form, and they themselves are called
conservative schemes. A family of classic conservative numerical schemes
often applied to unsteady flow pro
