Improving Sustainability of Urban Areas by Optimizing Rain Gardens Using GIFMod Software

Tema ovog rada jest modeliranje kišnih vrtova različitih propusnosti i provođenje analiza osjetljivosti u svrhu dobivanja znanja o rješavanju problematike urbanizacije i funkcioniranju održivih sustava odvodnje oborinskih voda te stručnosti o optimalnom dimenzioniranju. To je bilo provedeno hidrauličkim modeliranjem u SWMM i GIFMod računalnim programima. Zaključeno je da se propusnost ne može poistovjetiti samo sa njenom hidrauličkom provodljivošću te su izložena razna osmatranja dobivena pri dimenzioniranju kišnih vrtova. U radu su predložena potencijalna daljna ispitivanja parametara i modeliranja kišnih vrtova vezana uz parametre propusnosti tla.The topic of this paper is modeling of rain gardens of different permeability and carrying out a sensitivity analysis in order to gain knowledge about solving the problem of urbanization and functioning of a sustainable stormwater drainage system, as well as to gain expertise about optimal dimensioning. This was done by hydraulic modeling in SWMM and GIFMod computer programs. It was concluded that permeability cannot be equated only with its hydraulic conductivity, and various observations obtained during the dimensioning of rain gardens were presented. Potential further analysis of parameters and modeling of rain gardens related to soil permeability parameters are proposed in the paper
