Abstract

U razdoblju od siječnja do travnja 2013. godine na području Grada Samobora aktivirana su brojna klizišta kao posljedica oborina. U okviru ovog diplomskog rada prikupljeni su podaci o 45 klizišta iz različitih izvora: lokalne samouprave Grada Samobora, Područnog ureda za zaštitu i spašavanje Grada Zagreba, tehničkih izvješća i geotehničkih elaborata, kao i informacija iz medija. Također je provedeno i rekognoscirajuće kartiranje klizišta na terenu u svrhu provjere podataka i prikupljanja opisnih... More podataka o točnoj lokaciji klizišta, površini klizišta i elementima pod rizikom. Ovi podaci poslužili su za analizu pokretača klizanja, koja se sastojala od identifikacije oborinskih događaja uslijed kojega su klizišta pokrenuta, kao i definiranja intenziteta i trajanja identificiranih oborinskih događaja. Pri analizi oborina korišteni su podaci o oborinama s pet meteoroloških postaja: Samobor, Glažuta, Rakov Potok, Rude i Lipovec. Na osnovi prikupljenih podataka o točnim datumima aktivacije klizišta, utvrđeno je da su ekstremni vremenski uvjeti nastupili u proljeće 2013. godine. Na osnovi analize podataka o oborinama utvrđeno je 14 oborinskih događaja s vrijednostima intenziteta oborina u rasponu od 0,025 do 0,476 mm/h i vrijednostima trajanja oborina u rasponu od 48 do 2.088 sati. Usporedbom ovih podataka s krivuljama intenzitet-trajanje (tzv. ID krivulje) iz svjetske literature, proizlazi da su u analiziranom razdoblju na području općine Bednja nastala klizišta veličine od 500 do 1.500 m2, uslijed oborinskih događaja koji su premašili granične vrijednosti prema Guzzetti i dr. (2008) i globalne ID granične vrijednosti oborina prema Clarizia i dr. (1996), a odam događaja su također premašili i granične vrijednosti prema Guzzetti i dr. (2007). Less

Abstract: In the period from January to April 2013 in the city of Samobor numerous landslides were activated due to rainfall. Within this diploma thesis data were collected for 45 landslides from various sources: archive of local government, Regional Office for Protection and Rescue of Zagreb, technical reports and geotechnical studies, as well as information from the media. Field investigation was also performed in order to check data and to collect descriptive data of the exact location of... More landslides, size of landslides and elements at risk. These data were used to analyze triggers of landslides, which were consisted of the identification of rainfall events which caused landslides, as well as defining the intensity and duration of the identified rainfall events. Measurements obtained by five meteorological stations (Samobor, Glažuta, Rakov Potok, Rude i Lipovec) were used to analyze precipitation. Based on data collected on the exact dates of activation of landslides, it was found that the extreme weather conditions occurred in spring of 2013. Based on the analysis of data, 14 precipitation events were identified with the values of the intensity of rainfall ranging from 0.025 to 0.476 mm/h and the duration of precipitation values ranging from 48 to 2,088 hours. By comparing these data with curves intensity-duration (ID thresholds) from scientific literature, it was found that landslides were caused by precipitation events that exceeded the limit values according to Guzzetti et al. (2008) and global ID limit values according to Clarizia i dr. (1996). Moreover, eight events also exceeded the limit values according to Guzzetti et al. (2007). The landslide area of activated landslides is in a range of 500-1,500 m2. Less
