20.500.12556/RUL-163167 Modeliranje evtrofikacije Blejskega jezera magistrsko delo Eutrophication modelling of Lake Bled master thesis Blejsko jezero se kljub implementaciji večjih sanacijskih ukrepov za izboljšanje stanja jezera v preteklosti še vedno sooča z veliko pritiski iz okolice. V magistrski nalogi smo analizirali in modelirali vire obremenitev s hranili iz prispevnih območij ter vire, ki jezero obremenjujejo neposredno. V ta namen smo postavili dva modela: model spiranja hranil s porečja v orodju MapShed in model stanja jezera v programu AQUASIM. Predpostavili smo, da je fosfor edini omejitveni faktor, ki vpliva na kakovost jezera. Med drugimi vplivi, smo opazovali tudi vpliv hranjenja rib na stanje jezerskega ekosistema. Na podlagi umerjenih in validiranih modelov smo ugotovili, da k obremenitvi s fosforjem največ prispeva pritok Mišca in da ima velik vpliv na cvetenje alg notranja obremenitev jezera. V zaključkih smo predlagali ukrepe za izboljšanje stanja Blejskega jezera. Despite implementing vast rehabilitation measures to improve the state of Lake Bled in the past, it still faces many pressures from the surrounding area. In the master’s thesis, we analysed and modelled the sources of nutrient loads from the contributing areas and direct loads to the lake. For this purpose, we set up two models: the model of nutrient leaching from the catchment in the MapShed tool and the model of the state of the lake in the AQUASIM program. We assumed that phosphorus is the only limiting factor affecting lake quality. The influence of fish feeding on the state of the lake ecosystem was modelled and assessed along with the rest of the load from the catchment. Based on calibrated and validated models, we found that the Mišca tributary contributes the most to the phosphorous load and that the internal load of the lake has a significant influence on the algae bloom. In the conclusions, we proposed several measures for improving the state of Lake Bled magistrska dela modeliranje kakovost Blejsko jezero evtrofikacija MapShed AQUASIM master thesis modelling quality Lake Bled eutrophication true false false [L.
