20.500.12556/RUL-152021 Analiza erozijske nevarnosti poplavnih površin z uporabo 2D hidravličnega modela premeščanja sedimentov magistrsko delo št.: 116/II. VOI Erosion hazard analysis of floodplains using a 2D hydraulic sediment transport model master thesis no.: 116/II. VOI Leta 2007 sprejeta slovenska zakonodaja na področju voda v sklopu izdelave hidrološko-hidravličnih študij, ki veljajo kot strokovna podlaga projektni dokumentaciji in prostorskim aktom, zahteva tudi analizo erozijske nevarnosti. V nasprotju s postopkom za izdelavo poplavnih kart sta postopek in metodologija izdelave erozijskih kart slabo definirana. V praksi pogosto končni izdelki bolj temeljijo le na inženirskih predpostavkah in ocenjenih terenskih razmerah kot na dejanskih podatkih o lastnostih tal in hidravličnih razmerah ob visokovodnih dogodkih. V magistrski nalogi smo preverili možnost nadgradnje trenutnega pristopa kartiranja erozijske nevarnosti z vpeljavo 2D hidravličnega modela premeščanja sedimentov. Modeliranje transporta plavin je pogojeno z natančno izdelanim in stabilnim hidravličnim modelom, ki mu dodamo podatke o geološki sestavi tal. Velik vpliv na potek premeščanja pa ima tudi raba tal. Rezultati so odvisni tudi od izbora transportnih enačb in drugih parametrov premeščanja sedimentov. Z modelom smo natančneje opisali dinamiko erozijskih procesov na poplavnih površinah ter iz rezultatov izdelali karte erozijske nevarnosti in karte razredov erozijske nevarnosti. As part of the preparation of hydrological-hydraulic studies, which are considered as the technical basis for project documentation and spatial planning acts, the Slovenian water legislation, adopted in 2007, also requires an erosion hazard analysis. In contrast to the procedure for the production of flood maps, the procedure and methodology for the production of erosion maps are poorly defined. In practice, the final products are often based more on engineering assumptions and estimated field conditions than on actual soil properties data and hydraulic conditions during high water events. For the purpose of this master thesis, the possibility of upgrading the current erosion hazard mapping approach was examined by introducing a 2D hydraulic sediment transport model. Sediment transport modeling depends on a well-developed and stable hydraulic model which also includes the information about the geological soil composition. The land use has a major influence on the transport process as well. Furthermore, the results depend on the choice of transport equations and other sediment transport parameters. The results gained with the model were used to describe the dynamics of erosion processes on floodplains in more detail and to produce erosion hazard maps. gradbeništvo magistrsko delo VOI erozija erozijska nevarnost premeščanje sedimentov 2D hidravlično modeliranje karte erozijske nevarnosti civil engineering master thesis erosion erosion hazard sediment transport 2D hydraulic modelling erosion hazard maps true false false [A.
