Simulation of complex free surface flows [PDF]
ESAIM: Proceedings and Surveys, 2021 We study the Serre-Green-Naghdi system under a non-hydrostatic formulation, modelling incompressible free surface flows in shallow water regimes. This system, unlike the well-known (nonlinear) Saint-Venant equations, takes into account the effects of the

Approximation zones of the Saint-Venant equations f flood routing with overbank flow [PDF]
Hydrology and Earth System Sciences, 2000 The classification of river waves as gravity, diffusion or kinematic waves, corresponds to different forms of the momentum equation in the Saint-Venant system.

On the use of Saint Venant equations to simulate the spreading of a granular mass [PDF]
Journal of Geophysical Research: Solid Earth, 2005 Cliff collapse is an active geomorphological process acting at the surface of the Earth and telluric planets. Recent laboratory studies have investigated the collapse of an initially cylindrical granular mass along a rough horizontal plane for different initial aspect ratios a = Hi/Ri, where Hi and Ri are the initial height and radius, respectively.

Simulating the Influence of Buildings on Flood Inundation in Urban Areas
Geosciences, 2018 Two-dimensional hydraulic modeling is fundamental to simulate flood events in urban area. Key factors to reach optimal results are detailed information about domain geometry and utility of hydrodynamic models to integrate the full or simplified Saint ...

A multi-model approach to Saint-Venant equations: A stability study by LMIs [PDF]
International Journal of Applied Mathematics and Computer Science, 2012 Abstract This paper deals with the stability study of the nonlinear Saint-Venant Partial Differential Equation (PDE). The proposed approach is based on the multi-model concept which takes into account some Linear Time Invariant (LTI) models defined around a set of operating points.
