Abstract
Jaruženje je jedan od najrasprostranjenijih denudacijskih procesa u priobalnim dijelovima Sredozemlja. Razumijevanje intenziteta jaruženja važno je za rekonstrukciju promjena krajolika u prošlosti, ali i za predviđanje njegovog budućeg razvoja. Jaruge su na razini Hrvatske vrlo slabo proučavane. U ovom diplomskom radu predložen je koncept praćenja intenziteta jaruženja zasnovanog na korištenju digitalnih modela površina (DMP), izvedenih iz snimaka prikupljenih UAV fotogrametrijom. Da bi se odredilo odgovoravajuće područje za praćenje intenziteta jaruženja provedena je višekriterijska GIS analiza (GIS MCDA), utemeljena na različitim kriterijima (značajke terena, vegetacijski i pedološki pokrov, itd.). Na temelju GIS MCDA izvršena je raščlamba prostora otoka Paga s obzirom na podložnost terena jaruženju. Točnost izvedenih zona visoke podložnosti jaruženju potvrđena je na temelju postojećih jaruga, kartiranih kroz primjenu objektno-orijentirane analize (OBIA). Na temelju izdvojenih područja visoke podložnosti jaruženju i obavljenih terenskih izviđanja za detaljniju analizu odabrana je jaruga Santiš. Jaruga Santiš oblikovana je u naslagama smeđeg tla te su unutar nje zapaženi tragovi intenzivnog jaruženja. Praćenje intenziteta jaruženja i nastalih prostorno-vremenskih promjena unutar jaruge Santiš izvršeno je kroz usporedbu periodičkih DMP-ova visoke rezolucije. Da bi se promjene mogle kvantitativno opisati razvijen je egzaktni alat (GULIVER), namijenjen mjerenju vertikalnog pomaka unutar poprečnih presjeka jaruge. Predloženim konceptom uspješno je utvrđen i kvantificiran intenzitet jaruženja unutar šestomjesečnog razdoblja.
Abstract (english)
Gully erosion is one of the most prominent denudation processes at coastal parts of the Mediterranean. Understanding of gully erosion rates is important for reconstruction of past landscape changes and prediction of its further development. Studies considering gully erosion in Croatia are scarce. In this graduation thesis concept of using repeat UAV photogrammetry derived high-resolution digital surface models (DSM) for monitoring of gully erosion rates is presented. In order to determine most suitable area for detailed high accuracy monitoring of gully erosion GIS-MCDA was performed, that was based on different criteria (terrain attributes, lithologic cover, vegetation cover, etc.). GIS MCDA divided Pag Island into different zones, in regard to the gully erosion susceptibility. Extracted high gully erosion susceptibility zones were verified by the reference gullies that were mapped through the object-based image analysis (OBIA) approach. Based on extracted high gully erosion susceptibility areas and conducted field research gully Santiš was found. Gully Santiš, formed in deep soil sediments and with recorded intensive erosion was selected for in detailed survey. The monitoring of the gully erosion intensity and the resulting spatial-temporal changes within gully Santiš was performed by comparing the high resolution periodic DMPs. In order to be able to quantitatively describe the changes, an exact tool (GULIVER) is developed, designed to measure the vertical shift within the cross section of the gully. The proposed concept has successfully determined the gully erosion intensity within the six months study period.
