Abstract
Rad ukazuje na problem pojave erozije plaža i pravilnu procjenu i sprječavanje istog. S obzirom na to da je plažni materijal prva linija nailaska valova, lako dolazi do njegovog preslagivanja, pomicanja i trošenja zbog čega se narušava morfologija samog profila i stabilnost plaže. Osnovna mjera koju je potrebno poduzeti je nadohrana novim materijalom. Sama količina potrebna za nadohranu proizlazi iz procjene erodiranog i nasutog materijala te izgleda profila plaže nakon određenih valova. Ovim je radom dana kalibracija već poznatog analitičkog SHINGLE modela u odnosu na laboratorijska mjerenja. Vrlo su dobro imitirani prirodni uvjeti zato što uvjeti laboratorija s velikim valnim kanalom i generatorom u Hanoveru dozvoljavaju mjerenja u omjeru 1:1. Na inicijalni profil generiraju se valovi većih ili manjih valnih visina te se bilježi izgled profila nakon prolaska vala, a modeliraju se profili za valove koji prema Powellu rade aktivne promjene morfologije plaže u situacijama kad na trenutačni profil dolazi val veće valne visine od prethodnog vala. Dodatno je napravljena usporedba i kalibracija SHINGLE modela u odnosu na situaciju poravnavanja profila između dva mjerenja na inicijalni nagib 1:8.
Abstract (english)
This paper demonstrates the issue of beach erosion and adequate estimation and prevention of the same. Since the beach material is on the first line of wave ascension, it could be easily moved, transported or damaged which can reshape beach profile and endanger stability of the beach. Therefore, beaches need to be filled with gravel whose quantity comes from estimation of eroded and accrete material, as well as the appearance of beach profile after the waves. This paper presents the calibration of well-known analytical SHINGLE model and comparation with laboratory measurements in wave flume in Hanover, where field conditions were imitated very well due to great wave canal and generator, which enable the possibility of 1:1 experiments. Waves of higher or lower height were generated on the initial beach profile, which was recorded after every wave passage, and predictions with Shingle were only made for those that have made significant morphological changes according to Powell, in situations when the incoming wave has bigger wave height than the previous one. Additionally, the calibration of SHINGLE model was made and compared with situation of alignment of profiles between two measurements on initial slope 1:8.
