20.500.12556/RUL-138986 Geoinformacijsko vrednotenje odstranjevanja rečnih pregrad z vidika vpliva na migracije vodnih organizmov v slovenskih rekah GIS based assessment of riverine barrier removal in connection to the impact on aquatic organism migrations in Slovenian rivers V magistrskem delu smo z izdelavo prve skupne baze podatkov ugotovili število pregrad na slovenskih rekah in prepoznali potrebo po njihovem odstranjevanju z vidika vpliva na migracije vodnih organizmov. Z združevanjem več izvornih podatkovnih baz je prihajalo do zgoščevanja točk okoli ene lokacije, kar smo prepoznali kot duplikate. V ta namen smo oblikovali metodologijo odstranjevanja duplikatov, s katero smo dobili dejansko število pregrad, ki drobijo slovenske reke. V nadaljevanju smo opredelili kriterije, s katerimi smo merili vpliv pregrad na migracijo vodnih organizmov. Kriterije smo razvrstili v štiri scenarije odstranjevanja pregrad in jih glede na namen odstranitve različno obtežili. Izvedli smo dve metodi razvrščanja pregrad – zaporedno in odstotno – in rezultate kartografsko prikazali ter jih kritično ovrednotili. The master thesis tackles the abundance of barriers on the Slovenian rivers by creating first coherent barrier database as well as identifying the need for barrier removal in the scope of the influence towards water organisms’ migration. By combining data from multiple sources, we encountered point density which were recognised as duplicates. To eliminate them we applied a methodology which gave us the number of barriers that fragment Slovenian rivers. Furthermore, we identified criteria for measuring the influence towards water organisms’ migration. Criteria were classified into four scenarios and were weighted to suit the means for barrier removal. In the process we applied two methods of ranking – sequential and percent rank. The results are presented cartographically and critically assessed. rečne pregrade odstranjevanje duplikatov vpliv na vodne organizme scenariji geografski informacijski sistemi riverine barriers removal of duplicates impact on water organisms scenarios geographic information systems true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2022-08-26 13:55:57 2022-08-26 13:56:03 2022-09-15 04:17:34 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 501934 17784.pdf 17784.pdf 1 02B5EC223752CC20676C810DABB710DA ac6a6a7282e74b8c208dd3920a1e56f3cde0f6cca7b6d8b4db3bdc945b065607 08b4be18-2536-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=159490 Filozofska fakulteta 0 0 0
