20.500.12556/RUL-108756 Strižne obremenitve poplavnih območij pri visokovodnih dogodkih diplomska naloga Shear Stresses on Flood Areas during High Water Events graduation thesis Visokovodni dogodki so pogost pojav na ravninskih obrečnih območjih. Poplavnih dogodkov ne gre preprečevati, ampak zgolj obvladovati oziroma jih analizirati, da lahko zmanjšamo pričakovano škodo. Ob vsakem poplavnem dogodku lahko nastopi tudi odnašanje oziroma odlaganje materiala. Erozijske procese je težje obravnavati, eden od načinov pa je empirično določanje strižnih napetosti in nadaljnja presojanja odnašanja in odlaganja materiala. V diplomski nalogi so strižne napetosti obravnavane po različnih metodah, s katerimi lahko evidentiramo morebitna erozijsko izpostavljena območja. S kombinacijo podatkov geološke sestave in rabe tal lahko predvidimo, kje bo prihajalo do odnašanja in odlaganja materiala. Tok vode na poplavnih območjih v času visokovodnih dogodkov lahko povzroča veliko mehansko degradacijo tal. Nenadnega poslabšanja tal ne želimo, rodovitna tla so navsezadnje temelj za življenje, saj na njih pridelujemo hrano za ljudi. Čeprav je spreminjanje reliefa stalen in naraven pojav, smo nanj pozorni šele takrat, ko nastopi v velikih razsežnostih. Analiza je bila narejena na odseku reke Save med Krškim in Brežicami. Za obdelavo terena z vsemi predhodnimi izračuni po petih različnih metodah je bilo uporabljeno GIS orodje. Rezultati za izbrano območje prikazujejo karte erozijske nevarnosti in odlaganja materiala. High water events in flood areas are natural phenomena. To reduce the expected damage in these areas it is not appropriate to prevent these floods, but rather only to analyze and attempt to control them. On every high-water event it may also lead to erosion. As it is harder to examine the erosion processes, one way of determining them are empirical calculations of shear stress and further estimations of erosion and material deposition. In this thesis we demonstrate shear stresses in detail using several different methods, with which we can record possible erosion exposed areas. With combination of geological land structure and land use data we are able to predict possible areas of erosion and deposition of material. The flow of water in flood areas during high-water events causes great mechanical degradation of the soil. Soils are an important basis for life since they support the food production for human consumption. Erosion and deposition are a constant natural phenomenon, but these are noticed only when they occur on a large scale. Our analysis takes place on flood plains the river Sava along between the towns of Krško and Brežice. To process the previous calculations using five different methods, we used ArcGIS software. All results of selected area are shown at the end on soil erosion and material deposition maps.
