Abstract

V nalogi so prikazane izpeljave enačb valovanja morja po teoriji valov majhnih amplitud (linearna teorija valovanja). prvi del vsebuje izpeljavo osnovne diferencialne enačbe ob upoštevanju ustreznih robnih pogojev, ki opisujejo valove majhnih amplitud in reševanje osnovnega robnega problema z vsemi poenostavitvami. v drugem delu izpeljemo enačbo za dinamični tlak pod valom in podrobneje analiziramo odvisnost tlaka in njegove rezultante od parametrov v enačbah: globine vode, valovne dolžine in višine valovanja. grafični prikaz odvisnosti dinamičnega tlaka od razmerij med pari parametrov omogoča neposredno kvantifikacijo vpliva parametrov valovanja na dinamični tlak v širokem spektru razmer, ki se lahko pojavijo v naravnem okolju.

Secondary title: ǂThe ǂequations for sea level oscillations
Secondary abstract: In the thesis we demonstrate the derivation of the equations of small-amplitude sea waves (linear wave theory). in the first part, we establish the main differential equation and the boundary conditions, which describe the linear wave theory. we solve the boundary value problem with all the necessary simplifications. in the second part, the equations for the pressure field under a sea wave are derived. we further analyse the behavior of the pressure field and its resulting force in relation to all the relevant parameters: water depth, wave length, and wave height. we represent the dependence of the dynamic pressure to the ratio among pairs of parameters graphically, which enables us to directly quantify the effect of the parameters to the dynamic pressure for a wide range of conditions, which can appear in the natural environment.
