Abstract

U ovome završnom radu prikazane su hidrauličke analize protočnosti kanala trapeznog i pravokutnog oblika s posebnim naglaskom na stupanj hrapavosti i uvjete održavanja pokrova kanala. U uvodnom dijelu rada, prikazane su pretpostavke jednolikog stacionarnog tečenja, koje ćemo koristiti za potrebe proračuna protoka i brzine. Provedena je hidraulička analiza kojom je dan prikaz odnosa protočnosti kanala s uvjetima odražavanja pokrova za opći slučaj. Druga hidraulička analiza predstavlja analizu propusne moći korita potoka Slavjan (primjer regulacije u urbanoj sredini) na kritičnoj dionici za jedan ekstremni oborinski događaj. Ispitane su različite moguće varijante stanja korita koje se definiraju Manningovim koeficijentom hrapavosti. Na temelju provedenih analiza, došlo se do zaključka kako veći koeficijenti hrapavosti daju manju protočnost u kanalu i obrnuto.

Abstract (english)

In this thesis, hydraulic analyses of trapezoidal and rectangular channel are presented, with emphasis on the degree of roughness and maintenance conditions of the channel cover. In the introductory part of the paper, the assumptions of a uniform stationary flow, which will be used for the purposes of flow and velocity calculations, are presented. A hydraulic analysis was performed to give an overview of relationship between the channel flow and the cover conditions for the general case. The second hydraulic analysis represents an analysis of flow on the Slavjan stream (an example of urban channel regulation) through the critical section for one extreme rainfall event. Different possible variants of the channel condition are examined defined by the Manning coefficient of roughness. Based on the analyses, it was concluded that the higher roughness coefficients give smaller flows in the channel, and vice versa.
