Diseño de riego por melgas empleando las ecuaciones de Saint-Venant, y Green y Ampt

Tecnología y ciencias del agua, 2015
Se presenta un método de diseño de riego por melgas basado en la aplicación de un modelo que emplea las ecuaciones de Saint-Venant para describir el flujo del agua sobre el suelo, y la ecuación de Green y Ampt para representar el flujo del agua en el ...

A simple non-equilibrium bedload transport equation for the formation of dune in a shallowwater flow over an erodible bed

E3S Web of Conferences, 2018
In this work, we consider the long-standing problem of capturing dune formation in an erodible-bed channel at subcritical speed by using a reduced order model of depth-averaged equations.

Segmentation of a river using the Saint Venant equations

, 2010
The Saint Venant equations are widely used for modelling river systems for scenario simulations, flow prediction, control design, etc. In order to represent a river using the Saint Venant equations, the river is usually divided into segments which are ...

Online Model Identification Of Open-Channel System With High Order IDZ Model

MATEC Web of Conferences, 2018
In the control of open-channel, it is difficult to estimate wave propergation time because of the complexity of reflection, superposition and energy attenuation of shallow water waves. Although Saint-Venant equation have reasonable accuracy in describing

The quasiconvex envelope of the Saint Venant–Kirchhoff stored energy function

, 1995
We give an explicit expression for the quasiconvex envelope of the Saint Venant–Kirchhoff stored energy function in terms of the singular values. This envelope is also the convex, polyconvex and rank 1 convex envelope of the Saint Venant–Kirchhoff stored

Finite-volume solvers for a multilayer Saint-Venant system

, 2007
We consider the numerical investigation of two hyperbolic shallow water models. We focus on the treatment of the hyperbolic part. We first recall some efficient finite volume solvers for the classical Saint-Venant system.
