20.500.12556/DKUM-39375 SANACIJA STRUGE MISLINJE NA OBMOČJU NEKDANJE HE V PAMEČAH RECONSTRUCTION OF THE MISLINJA RIVER STREAM CHANNEL IN THE FORMER HPP PAMEČE AREA V prvem delu diplomske naloge smo predstavili kratek opis povodja Mislinje. Navedene so osnovne topografske in hidrografske lastnosti ter zgodovina povodja. V nadaljevanju je podrobneje obravnavan odsek povodja Mislinje v Pamečah pri Slovenj Gradcu. Podan je podroben opis obstoječega stanja na odseku, kjer se na omejenem področju srečamo z dotrajanimi vodnimi objekti – obrežnimi zidovi, kakor tudi z dokaj visokim in neprimernim pragom, ki onemogoča migracijo vodnih živali. Predstavili smo hidravlike osnove pri računanju enodimenzionalnega toka. Izdelali smo hidravlični računski model odseka s pomočjo HEC-RAS, verzija 4.1. ter izvedli izračune gladin s povratnimi dobami 5, 10, 20, 50 in 100 let. Hidravlične izračune smo izvedli tudi z novimi robnimi pogoji in jih primerjali z obstoječimi. Rezultat je pokazal, da smo s predvidenimi ukrepi izboljšali varnost brežin ter dosegli dodatno varnost tudi pri pretoku Q100. In the first part of the work we have presented a brief description of the river basin of Mislinja. Those are the basic topographic and hydrographic characteristics and the history of the river basin. The following is discussed in more detail the section of the river basin Mislinja in Pameče part of Slovenj Gradec. It is given a detailed description of the present situation in the section where we meet on a limited area of the worn out hydraulic structures - banks as well as a high and inappropriate crest, which obstructs the migration of aquatic animals. We have presented the theoretical base of 1D river flow hydraulics. We have developed a hydraulic model of river channel using HEC-RAS, Version 4.1. and performed calculations of water levels with return periods of 5, 10, 20, 50 and 100 years. Hydraulic calculations were also carried out with the new boundary conditions and compared them with the existing ones. The results showed that with the proposed measures the security of river banks and achieve additional safety even at extreme flows - Q100. porečje reke Mislinje urejanje površinskih voda poplavna varnost hidravlični model HEC-RAS Mislinja river basin surface water management flood safety hydraulic modeling HEC-RAS true true false [A.
