Dam-break is a serious disaster resulting in severe damage to downstream communities. Therefore, analyzing the affected range and evolution process of dam-break floods advance valuable. However, difficulties challenges lie complexity breaking earth-rock dams, uncertainty floods, geographical variability. Given this, objective this study analyze characteristics flood evolution. The chooses Cheng...

Abstract The object of this paper is the Saint-Venant torsion a solid elliptical cylinder made orthotropic homogeneous piezoelectric material. We find shape cross section which does not warp under applied torque. sizes section, has maximum value torsional rigidity for given cross-sectional area, are also determined.

This survey paper is focused on the Saint-Venant inequality for the Laplace operator with Robin boundary conditions. In a larger context, we make the point on the recent advances concerning isoperimetric inequalities of Faber-Krahn type for elastically supported membranes and describe the main ideas of their proofs in both contexts of rearrangement and free discontinuity techniques.

In this paper, the existence of a solution in the form of a minimizer or microstructure is established for the boundary value problems of nonlinear elasticity with certain nonconvex stored energy functions such as those of St. Venant-Kirchhoff type materials. Necessary and sufficient conditions for minimizing sequences of the potential energy to converge to a minimizer or to microstructure are ...

flood routing in rivers is a mathematical procedure to determine flow hydrograph at a point in a river. one of routing methods is based on solution of saint-venant equations for unsteady flows. because this method is very complex and need to more information of river, other methods with simple calculations and reasonably accurate results have been extended and give generally satisfactory result...

The overelevation of the water table in surface irrigation plots is one main factors affecting salinization agricultural soils. Therefore, it necessary to develop simulation models that consider effect a shallow process advance-infiltration an event. This paper, first series three, develops simple mathematical model for advance phase border soils with presence table. In this study, hydrodynamic...
