Vpliv meteoroloških spremenljivk na pogostost padanja kamenja v Baški grapi

Rekanje, Blaž (author), Kobal, Milan (mentor)

Na treh testnih območjih v Baški grapi smo izvedli periodične popise padajočega kamenja. Na Selih nad Podmelcem smo z meteorološko postajo merili meteorološke spremenljivke. Podatke smo vnesli v tabele in uredili v programu Microcoft Excel. V programu ArcMap smo za vsako območje izračunali prispevno območje in površino možnih izvorov kamenja. S programom Rstudio smo izračunali korelacije in linearni model regresije med območji, kategorijami izvora ter meteorološkimi spremenljivkami. Rezultati niso pokazali statistično značilnih povezav med pogostostjo padanja kamenja in meteorološkimi spremenljivkami v Klavžah. Padavine so pozitivno povezane s pogostostjo padanja kamenja v Lojah 1 in Lojah 2 ter v vseh kategorijah izvora. Z naraščanjem temperature zraka in tal se pogostost padanja kamenja v Lojah 1, Lojah 2 in vseh kategorijah izvora manjša. Dnevne amplitude temperature zraka in tal ne kažejo značilne povezave s številom kamenja. Padavine ter temperature zraka in tal imajo večji vpliv na pogostost padanja kamenja iz brežine kot višje iz izvorov. V raziskavi nismo zaznali statistično značilnih korelacij vetra s pogostostjo padanja kamenja.

• Title: The effect of meteorological variables on frequency of rockfall in Baška grapa

Abstract

Periodical surveys of rockfall were made on three test sites in Baška grapa. We measured weather variables with a meteorological station located in Sela nad Podmelcem. The data was entered and organised in the Microsoft Excel software. We calculated watershed and areas of potential rockfall source for every test site in ArcMap software. We performed correlation and linear regression model for each test site, category of source and weather variables in RStudio software. The results showed no statistical significance between the frequency of rockfall and weather variables in Klavže. Precipitation is positively linked with the frequency of rockfall in Loje 1, Loje 2 and all categories of source. With rise of air and ground temperatures the frequency of rockfall in Loje 1, Loje 2 and all categories of source declines. Daily air and ground temperature amplitudes don’t show any significant correlation with the number of rocks. Precipitation, air and ground temperature have greater effect on the frequency of rockfall from the strand than from higher source areas. No statistically significant correlation was found between the wind and rockfall frequency.
