Hydraulic Model of Lake Vrana in Existing and Designed Condition : Master's Thesis

U ovom diplomskom radu prikazan je hidraulički model funkcioniranja Vranskog jezera koji opisuje promjenu vodostaja u jezeru, uzimajući u obzir dotoke od oborina, podzemne gubitke prema moru, otjecanje kanalom Prosika, potrošnju vode za navodnjavanje i vodoopskrbu, te isparavanje vode s jezerske površine. Modelom je analiziran rad sustava za postojeće i za projektirano stanje u dvije varijante oblaganja kanala Prosika. Model je izrađen u programskom jeziku FORTRAN 95. Napravljen je na temelju mjerenja vodostaja jezera i mora za 2010., 2011., 2012., 2013. i 2014. godinu. Rezultati proračuna su razine u jezeru te odgovarajući protoci za postojeće i za modelirano stanje.In this graduate thesis hydraulic model has been developed describing the change of water level in Lake Vrana, having regard to the inflow of the precipitate, the sea underground losses, runoff through channel Prosika, water consumption for irrigation and water supply, and water evaporation from the lake surface. The model analyzes the operation of the system for the existing and for the designed condition in two variants of the Prosika canal lining. The model was developed in the FORTRAN 95 programming language. It was made based on gathered data of lake and sea level from 2010., 2011., 2012., 2013. and 2014. The results of the calculation are the variations of lake level and the corresponding water flows for the existing and for the modeled state
