Abstract

Napravljen je idejni projekt poboljšanja plovnosti rijeke Drave pomoću tradicionalnih pera. Prikupljene i obrađene su sve potrebne geodetske i kartografske podloge te su napravljene hidrološke obrade i dobiveni su ulazni i izlazni podaci za 2D HEC-RAS model koji je kalibriran koristeći Manningov koeficijent. Model je napravljen u postojećem stanju za srednji i niski plovni vodostaj u matematičkom hidrauličkom programu HEC-RAS. Nakon analize postojećeg stanja napravljena su 4 varijantna rješenja sa različitim odmacima od plovnog puta i različitim tlocrtnim rasporedom tradicionalnih pera. Povećanje brzine toka, a time i povećanje erozijske sposobnosti vodotoka za posljedicu ima produbljenje korita što je neophodno zbog nedostatnih dubina na dvije kritične lokacije gdje su smještena tradicionalna pera na dionici od rkm 8+000 do rkm 12+000 za plovidbu brodova IV. klase. Analizom brzina po osi plovnog puta 4 varijantnih rješenja napravljeno je konačno rješenje koje pokazuje ujednačeno povećanje brzine na dvije kritične lokacije u odnosu na ostala 4 varijantna rješenja. Za odabrano rješenje korištenjem proračuna konstrukcije dokazana je njegova stabilnost, izrađen je troškovnik te potrebni nacrti.

Abstract (english)

In this master's thesis, preliminary design of river channel stabilization with conventional groynes for facilitation of navigation on Drava River was made. All necessary geodetic and cartographic bases were collected and processed, hydrological graphs were made and input and output data were obtained for the 2D HEC-RAS model which is calibrated using the Manning coefficient. The model was made for the existing condition for Qmean and Q94% in mathematical hydraulic program HEC-RAS. After the analysis of the existing situation, 4 variant solutions were made with different distances from the fairway and different locations of conventional groynes. The increase of flow velocity has impact on erosion capabilities which is necessary due to the insufficient fairway depth at two critical locations where conventional groynes were put from rkm 8+000 to rkm 12+000 for navigation of IV. class ships. By analyzing the velocities along the axis of the fairway of 4 variant solutions, final solution was made which shows an uniform increase in velocity at two critical locations compared to the other 4 variant solutions. For the final solution, using construction calculation, its stability was proven, a cost estimate and necessary drawings were made.
