Abstract
The discrepancy between the theoretical solution of the Saint-Venant equations
for flood routing calculations and the problems encountered during practical
implementation is often quite big. This paper tries to give an overview of the
different bottle necks and the possibilities to cover the gap between theory and
practice. After a brief overview of the equations used for steady and unsteady
flow simulation, collection of topographical and hydraulic data is discussed.
Then follows some practical considerations on the processing of input data on
cross-sections, longitudinal profile and friction coefficient. Finally the impact of
different approaches on the quality of the nu
