Abstract	Glavni zadatak ovog diplomskog rada jest laboratorijskim mjerenjem odrediti polje brzine u okolici fizikalnog modela pregrade na Neretvi. Prvo, oblikovan je trodimenzionalni fizikalni model pregrade u programu 123D Design kako bi se dobila .stl datoteka. Nakon toga, datoteka .stl je otvorena u Objet Studio gdje su denfirani gradivni materijali pregrade, temelja i ostalih pomoćnih elemenata (prizmatični element s aeracijskim otvorima, čep, šipka). Kada je sve bilo denirano, sačuvana je datoteka .objtf koja je poslana na printanje Connex 3D printerom. Drugo, nakon što je numerički definiran odnos između pomaka u i vanjskog kuta Ɵ, programirana je robotska ruka R12, koja pokreće pregradu prilikom podizanja i spuštanja. Na kraju, korištena je PIV tehnologija, tj. učinjeno je ispitivanje pomoću digitalne kamera i lasera, dok je program DaVis 3.0 korišten radi obrade dobivenih podataka. Dobiveni rezultati polja brzine prikazani su u vektorskom obliku. Osim polja brzine, ispitano je vrtloženje oko z osi te intenzitet vrtloženja. Kao što se pretpostavljalo, tijekom podizanja i spuštanja pregrade dolazi do povećanja brzine uz postupno približavanje stacionarnom tečenju.
Abstract (english)	The main objective of this thesis is to define the velocity field in the vicinity of the physical model of the Neretva river-barrier through laboratory measurements. Firstly, the physical model of the barrier had been recreated in 3D by using 123D Design in order to obtain the .stl file format, which was subsequently opened in Objet Studio. The latter was used to define the building materials of the barrier, its foundations and other auxiliary elements (prismatic element with ventilation holes, cap and rod). Having completed the above, the .objtf file was saved and sent to print on the Connex 3D printer. After having defined the numerical ratio between the u shift and the Ɵ outer corner, the robotic R12 arm was programmed in order to run the barrier in the operations of lifting and lowering. Finally, the PIV technology and testing via the camera and the laser were applied, while the DaVis 3.0 program was used to process the obtained data. The results of the velocity field were displayed in vector format. In addition to measurements of the velocity field, values regarding the whirling motion around the z rotation-axis and swirling strenght were tested. As hypothesized, there has been a speed-increase accompanied by a gradual approach to the stationary flow when raising and lowering the barrier.
