Consistent initial conditions for the Saint-Venant equations in river network modeling [PDF]
Hydrology and Earth System Sciences, 2017 Initial conditions for flows and depths (cross-sectional areas) throughout a river network are required for any time-marching (unsteady) solution of the one-dimensional (1-D) hydrodynamic Saint-Venant equations.

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.

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.

Third Order Reconstruction of the KP Scheme for Model of River Tinnelva [PDF]
Modeling, Identification and Control, 2017 The Saint-Venant equation/Shallow Water Equation is used to simulate flow of river, flow of liquid in an open channel, tsunami etc. The Kurganov-Petrova (KP) scheme which was developed based on the local speed of discontinuity propagation, can be used to
