SAINT-VENANT TYPE ESTIMATE FOR THE WAVE EQUATION
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2002 Bu çalışmada hızı azalan bir dalga denklemi için Uzaysal Azalım Kestirimi elde edilmiştir. Yük bölgesinden uzaklaşıldıkça son etkilerin, en azından kısa zaman aralıkları için çok hızlı bir şekilde azaldığı görülmüştür.

Direct sensitivity computation for the Saint-Venant equations with hydraulic jumps [PDF]
, 2008 International audienceThis Note presents a new Riemann solver for the Saint-Venant equations in conjunction with the sensitivity problem when the solutions are discontinuous. The solver is based on the a priori assumption of two rarefaction waves.

A well-balanced solver for the Saint Venant equations with variable cross-section [PDF]
Journal of Numerical Mathematics, 2015 AbstractIn this paper we construct a numerical solver for the Saint Venant equations. Special attention is given to the balancing of the source terms, including the bottom slope and variable cross-sectional profiles. Therefore a special discretization of the pressure law is used, in order to transfer analytical properties to the numerical method. Based

The effect of water stage on the infiltration rate for initially dry channels
, 2007 Several hydrological models that are used for simulating the water flow in rivers and channels are based on the shallow water equations as in Copeland and El-Hanafy, (2006) or Saint Venant equations (El-Hanafy and Copeland, 2007a). Both the shallow water

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.
