Uporaba matematičnih modelov kakovosti vodotokov pri določanju biološkega minimumaKrajnc, UrošZagotavljanje biološkega minimuma pomeni spremembo ali ohranitev abiotskih dejavnikov okolja. Spremembo abiotskih faktorjev lahko dosežemo na tri načine: s spremembo pretokov, kar poveča vodostaje v ... reki, hitrosti in s tem povečamo transportno sposobnost, boljšo reaeracijo ..., spremembo kakovosti dotekajoče vode, kar vpliva na procese razgradnje in primarne produkcije, posledično pa na sekundarno produkcijo ter spremembo morfologije struge, s katero lahko tako povečamo hitrosti vode v matici struge kot tudi ustvarimo na izbranih odsekih ugodne pogoje za razvoj redkih in ogroženih biocenoz. Za usklajevanje potrebnih pretokov v rečni strugi s kakovostjo pretakajoče vode in ustvarjanje ustreznih abiotičnih dejavnikov (temperatura, kisik, hranila, bilanca onesnaženja) je pri identifikaciji problema nepogrešljiva ocena stanja (sedanjega, bodočega) z matematičnimi limnološkimi modeli. Ti modeli služijo za identifikacijo vzrokov sedanjih problemov ter napoved vpliva sprememb abiotskih faktorjev (pretok, kakovost vode, morfologija struge) z predvidenimi posegi. Iz raziskav izvorov onesnaženja reke Ohio ter vplivov na javno vodoskrbo, izvira en prvih matematičnih modelov v vodnem okolju, STREETER - PHELPSOVA enačba iz leta 1925, ki opisuje vsebnost raztopljenega kisika v vodi za izpustom odpadne vode. Danes se uporabljajo naslednji limnološki modeli: modeli temperaturnega obnašanja rek, modeli kvalitete voda rek, enodimenzionalni modeli kvalitete voda jezer in akumulacij, dvo in trodimenzionalni modeli za jezera in akumulacije, ekološki modeli jezer, modeli porazdelitve in učinkov toksičnih snovi v rekah in jezerih ter modeli kvalitete talne vode. Uporaba matematičnih limnoloških modelov ima v slovenskem prostoru dolgoletno tradicijo pri obravnavi tako stoječih kot tekočih voda.Source: Zbornik referatov (Str. 67-86)Type of material - conference contributionPublish date - 1993Language - slovenianCOBISS.SI-ID - 8024342
