Abstract

Izrađen je numerički model strujanja vode na preljevu brane Butoniga s ciljem analize rezultata kako bi se potvrdila ili opovrgnula hipoteza o poboljšanju hidrauličkih performansi povećanjem nadvišenja krune preljeva za 1,0 m. U uvodu su istaknuti izazovi inženjerskog planiranja u složenim hidrauličkim sustavima, gdje upravljanje vodama i rizici od poplava predstavljaju ključni aspekt inženjerskog planiranja. U drugom poglavlju prikazane su karakteristike tečenja preljeva i brzotoka. Opisane su hidrauličke karakteristike bočnog preljeva te je okarakteriziran tok vode ubrzotoku. Numerički model izrađen je koristeći geodetske, hidrauličke ihidrološke podloge. U HEC-RAS programu simulira se prelijevanje zapostojeće stanje preljeva, kao i za slučaj produljenja preljeva, za vodnevalove 100, 1000 i 10000-godišnjeg povratnog razdoblja. U diskusiji jedana detaljna analiza dobivenih rezultata.

Abstract (english)

A numerical model of water flow at the spillway of the Butoniga dam was developed with the aim of analyzing the results to confirm or refute the hypothesis regarding the improvement of hydraulic performance by increasing the spillway crest elevation by 1.0 m. The introduction highlights the challenges of engineering planning in complex hydraulic systems, where water management and flood risks represent key aspects of engineering planning. The second chapter presents the characteristics of spillway flow and rapids. Hydraulic characteristics of the side spillway are described, and the water flow in the rapids is characterized. The numerical model was developed using geodetic, hydraulic, and hydrological data. Spillage is simulated using the HEC-RAS program for both the existing spillway conditions and the case of spillway extension, considering water waves of 100, 1000, and 10000-year return periods. A detailed analysis of the obtained results is provided in the discussion.
