Design of hydraulic structures on canals

U ovom radu opisan je postojeći sustav površinske odvodnje u Zagrebačkoj županiji kojemu je potrebna revitalizacija. U tu svrhu dimenzionirale su se tri hidrotehničke građevine: ustava, preljev i hidrotehnička stepenica. Pogledom pedoloških karakteristika tla, klimatoloških prilika, postojeće poljoprivredne proizvodnje te topografskih značajki područja predložene su pozicije objekata te je napravljen hidrološki proračun. Hidrauličkim proračunom dimenzionirani su objekti te prikazan njihov utjecaj na režim voda.This paper describes the existing surface drainage system in Zagreb County that needs revitalization. For this purpose, three hydrotechnical structures were designed: the transition, the overflow and the hydrotechnical step. Pedological characteristics of the soil, climatological conditions, existing agricultural production and topographic features of the area were analyzed and according to it, the positions of stated structures were selected and a hydrological calculation was made. Hydraulic calculation were used to design the structures and show their impact on the water regime
