Abstract

The influence of a sheared velocity profile on the wavelength of standing small amplitude surface waves M. Bouhadef Algeria ABSTRACT The small amplitude surface waves propagation problem, in the general case of a sheared flow, is studied. The phase velocity determination leads to an eigenvalues problem which can be solved by a one-dimensional Galerkin finite element method. The wavelength of standing waves is determined, for each velocity profile, and compared to that measured in an open horizontal channel with an obstacle lying on the bottom.. INTRODUCTION The small amplitude surface waves propagation problem was subject to many studies ( [1], [2], [3] ) conducted generally in the particular case of shallow water, which means an hydrostatic pressure distribution . This paper is concerned with an arbitrary pressure distribution and Froude number and is an extension of [4] and [5] in which experim
