Abstract
Prezentirana je potencijalna mogućnost primjene javno dostupnih baza podataka s ciljem procjene opasnosti plavljenja grada Pule za malu, srednju i veliku vjerojatnost pojavljivanja visokih razina mora. Proračun površine plavljenja proveden je u GIS sučelju, te je baziran na vremenskim nizovima reziduala modeliranih morskih razina u satnoj rezoluciji za razdoblje 1990.-2020. te digitalnom modelu visina (EU-DEM_25), sve iz COPERNICUS baze podataka. Razine mora za tri odabrane vjerojatnosti pojavljivanja na predmetnim lokacijama definirane su analizom ekstremnih nizova maksimalnih vrijednosti po segmentima (uz prilagodbu opće razdiobe ekstremnih vrijednosti) i niza premašaja praga (uz prilagodbu opće Pareto razdiobe). Za potrebe procjene greške rezultata dobivenih korištenjem javno dostupnih baza podataka, komparativno je proveden isti metodološki slijed proračuna, ali baziran na komercijalnim vremenskim nizovima mjerenih razina mora sa mareografskih postaja, te na detaljnijem digitalnom modelu visina Državne geodetske uprave u rezoluciji 5 m (DGU-DEM_5). Rezultati provedenog istraživanja pokazuju da razlika prognoziranih maksimalnih razina mora iznosi samo -6.25 cm (manje razine mora pri korištenju javnih podataka), dok su procijenjene poplavljene površine 4,3 % veće (VGP 4% i 1%) i 7,3 % manje (VGP 0,1%) u slučaju primjene javno dostupnih podataka. Shodno dobivenim rezultatima, zaključuje se da je glavni izvor odstupanja procijenjene površine plavljenja uzrokovan razlikom u modelima reljefa te u značajno manjoj mjeri razlikom u podacima o razinama mora iz COPERNICUS baze i izmjerenih mareografskih podataka.
Abstract (english)
Here is presented the potential possibility of applying publicly available databases with the aim of assessing the risk of flooding Pula for low, medium and high probability of occurrence of high sea levels.The calculation of the flooded area was carried out in the GIS interface, and is based on time series of modeled sea level residuals in hourly resolution for the period 1990- 2020. and the digital height model (EU-DEM_25), from the COPERNICUS database. Sea levels for the selected probabilities of occurrence at the locations in question are defined by analyzing the extreme series of maximum values by segments and the series of exceeding the threshold (with adjusting the general Pareto distribution).For the purposes of assessing the error of the results obtained using publicly available databases, the same methodological sequence of calculations was carried out comparatively, based on commercial time series of measured sea levels from mareographic stations, and on a more detailed height model of the State Geodetic administration with a resolution of 5 m (DGU-DEM_5 ). The results of the conducted research show that the difference in forecast maximum sea levels, when using public data is only -6.25 cm, while the estimated flooded areas are 4.3% higher (VGP 4% and 1%) and 7.3% lower ( VGP 0.1%) in case of application of publicly available data. It is concluded that the main source of deviation of the estimated flooded area is caused by the difference in the terrain models and, to a significantly lesser extent, by the difference in the sea level data from the COPERNICUS database and the measured tide data.
