| abstracts | The paper is concerned with the problem of gravitational wave propagation in water ofvariable depth. The problem is formulated in the Lagrangian description, and the ensuingequations are solved numerically by a finite element method. In computations a convectingmesh that follows the material fluid particles is used. As illustrations, results of numericalsimulations carried out for plane gravity waves propagating over bottoms of simple geometryare presented. For parameters typical of a laboratory flume, the transformation of a transientwave, generated by a single movement of a piston-like wave maker, is investigated. Theresults show the evolution of the free-surface elevation, displaying steepening of the waveover sloping beds and its gradual attenuation in regions of uniform depth. |
