Abstract

U ovome diplomskom radu prikazana je problematika projektiranja šljunčanih plaža. Provedene su analize na dva poprečna profila različitih konstrukcija u pogledu duljine plaže, dubine te nagiba pokosa. Za potrebe proračuna optimalnog rješenja napravljeni su modeli koji su simulirali ponašanje šljunčanog materijala uslijed valnog djelovanja pomoću softvera XBeach-G. Uzevši u obzir koeficijente provodljivosti i transporta, prvobitne analize su modificirane kako bi sa većom točnošću dale realan prikaz premještanja šljunčanog materijala. Kao glavni kriterij vrednovanja pojedinog rješenja odabran je financijski aspekt troškova vraćanja žala u prvobitno, projektirano stanje pomoću građevinske mehanizacije. Na temelju količine premještenog materijala i cijene njegovog nadomjeska odabrano je optimalno rješenje u pogledu duljine plaže, dubine te frakcije zrna šljunka kojim bi se izgradila konstrukcija plaže.

Abstract (english)

In this thesis, the problem of designing gravel beaches is presented. Analyzes were carried out on two cross sections of different constructions regarding the length of the beach, depth and slope. For the purposes of calculating the optimal solution, models were created that simulated the behavior of gravel material due to wave action using the XBeach-G software. Taking into account the conductivity and transport coefficients, the original analyzes were modified in order to give a more accurate representation of the dislocation of the gravel material. The financial aspect of the costs of restoring the beach cross section to its original, designed state was chosen as the main criterion for evaluating a particular solution. Based on the amount of dislocated material and the price of its replacement, the optimal solution was chosen in terms of the length of the beach, the depth and the fraction of gravel grains that
would be used to build the beach structure.
