Abstract

Rad ističe problem pojave erozije plaža i poznavanje pravilne metodologije procjene i predviđanja iste s ciljem usporavanja i spriječavanja razaranja obale. Plaže služe kao obrambena linija kopna zbog čega je plažni materijal stalno podvrgnut destruktivnom djelovanju valova. Kao protupmjera, plaže se dohranjuju novim materijalom. U Ujedinjenom Kraljestvu uobičajena je praksa dohranjivanje šljunčanim plažnim materijalom s obzirom na njegovu visoku efikasnost u disipaciji valne energije. U posljedna dva desetljeća došlo je do većeg interesa za poznavanje morfodinamičkog ponašanja šljunka u području projektiranja plaža.
Ovim radom opisani su empirijski SHINGLE model i numerički XBeach-G model. Dane su važeće jednakosti pojedinog modela te su opisana terenska i laboratorijska mjerenja na temelju kojih su kalibrirani. Provedena je kalibracija XBeach-G modela prema laboratorijskim mjerenjima korištenim za kalibraciju, također prikazanog, SHINGLE modela. Dodatno su izrađeni numerički i empirijski modeli dva neovisna profila plaže kako bi se provela usporedba dvije metode i provelo ispitivanje simulirane pojave erozije i naknadnog oporavka plaže uslijed olujnog događaja.

Abstract (english)

The paper highlights the problem of beach erosion and knowledge of proper methodologies for estimating and predicting it in order to slow down and prevent the destruction of coastline. Beaches are a natural defence against erosion teherefore beach material is constantly subjected to the destructive effects of waves. As a countermeasure, beaches are being replenished with new material. In the United Kingdom, it is common practice to supplement beaches with gravel due to its high efficiency in wave energy dissipation. In the last two decades, a great interest has been shown in knowing the morphodynamic behavior of gravel beaches in the field of coastal engineering. This paper describes the empirical SHINGLE model and the numerical XBeach-G model. Main equations of each model are descibed and so are field and laboratory measurements on the basis of which they are calibrated. XBeach-G models were calibrated according to the laboratory measurements used to calibrate SHINGLE models. Additionally, numerical and empirical models of two independent beach profiles were developed in order to compare the two methods and conduct a simulation of profile erosion due to the storm event and subsequent recovery of the beach.
