Thermal mixing of the Sava iver in the future Brežice reservoir |
Sekundarni povzetek: |
Graduation thesis is discussing mixing processes and thermal pollution of the Sava River at the
location of future reservoir Brežice. The reservoir will be extending from a weir located in the vicinity
of Nuclear power plant Krško to the future dam at the location of hydroelectric power plant Brežice.
We were interested on the influence of cooling water on the thermal conditions of the Sava River in
the future conditions. We analysed the results of a three-dimensional simulations that had been made
with mathematical model PCFLOW3D. The results of simulations were section profile images with
temperature contour lines. With a help of these results, we defined the future location of complete
mixing. We were checking if temperatures are going to be in compliance with regulations. We
analysed the current conditions with one-dimensional mathematical model HOTRIVER. Evaluation of
model results was made with the assistance of temperature measurements in the Sava River.
Measurements were made on several locations in July and September in year 2010. In this way we
have defined current thermal conditions in the region of the future accumulation Brežice and we have
compared it to the future conditions. |

V diplomski nalogi smo obravnavali procese toplotnega mešanja Save na območju bodočega bazena
Brežice. Bazen se bo raztezal od jezu pri Nuklearni elektrarni Krško (NEK) do bodoče pregrade pri
hidroelektrarni Brežice. Zanimalo nas je, kako bo hladilna voda iz NEK v bodočem stanju vplivala na
toplotne razmere Save na tem območju. Analizirali smo rezultate tridimenzionalnih simulacij, ki so
bile izvedene s pomočjo matematičnega modela PCFLOW3D. Izrisali smo toplotne izolinije v
posameznih prečnih prerezih struge. Na podlagi teh rezultatov smo nato določili bodočo točko
popolnega premešanja savske vode z hladilno vodo. Kontrolirali smo, če bodo temperature v skladu z
zakonskimi omejitvami. Naredili smo analizo sedanjega stanja z enodimenzionalnim modelom
HOTRIVER. Pri vrednotenju rezultatov modela smo si pomagali z meritvami temperature Save, ki so
bile izvedene v mesecih julij in september leta 2010 na različnih lokacijah dolvodno od izpusta
hladilne vode. Na ta način smo definirali trenutne toplotne razmere na območju bodočega bazena
Brežice in nato izvedli še primerjavo z bodočimi razmerami. |
