Primena matematičkog meodeliranja strujanja podzemnih voda u hidrotehničkom uređenju prostora-primer Kameničke ade i Ribarskog ostrva u Novom Sadu
Application of mathematical modeling of groundwater flow in hydrotechnical spatial development - case study Kamenicka ada and Ribarsko ostrvo in Novi Sad
Hidrotehničko uređenje određenog prostora u većini slučajeva utiče na izmenu režima podzemnih voda. Za potrebe sagledavanja i kvantifikacije uticaja u savremenoj praksi sve veću primenu imaju numerički modeli. Projektna dokumentacija za područje leve obale Dunava u Novom Sadu u zoni Kameničke ade i Ribarskog ostrva, obradila je pomeranje linije nasipa za oko 500 m prema koritu Dunava i formiranje veslačke staze na delu Šodroš Dunavca. Na kalibrisanom matematičkom modelu, za predloženu konfiguraciju objekata i promenljive hidrološke uslove, kroz seriju prognoznih hidrodinamičkih proračuna simulirani su različiti scenariji uređenja. Rezultati hidrodinamičkih proračuna su upoređivani sa rezultatima simulacije strujanja podzemnih voda u postojećim uslovima. Analizom rezultata za odabrane varijante, sagledan je i kvantifikovan uticaj na izmenu režima podzemnih voda na prostoru Kameničke ade i Ribarskog ostrva. Obradom je utvrđeno da pomeranje linije nasipa ka Dunavu nema znatan uticaj na režim podzemnih voda, dok bi se izgradnjom veslačke staze ostvario pozitivan uticaj na trenutno ugrožena naselja Telep, Liman i Adice.
Hydrotechnical arrangement of a certain area in most cases affects the change of the groundwater regime. Numerical models are increasingly being used for the purpose of understanding and quantifying the impact in modern practice. The project documentation for the area of the left bank of the Danube in Novi Sad, in the area of Kamenička Ada and Ribarsko ostrvo, dealt with the displacement of the embankment line by about 500 m towards the Danube bed and the formation of a rowing path on the part of Šodroš Dunavac. On the calibrated mathematical model, for the proposed configuration of the facilities and changing hydrological conditions, through a series of prognostic hydrodynamic calculations, different development scenarios were simulated. The results of the hydrodynamic calculations were compared with the results of the groundwater flow simulation in the existing conditions. By analyzing the results for the selected variants, the influence on the change in the underground water regime in the area of Kamenička Ada and Ribarsko ostrvo was analyzed and quantified. The analysis determined that the displaement of the embankment line towards the Danube has no significant impact on the groundwater regime, while the construction of the rowing path would have a positive impact on the currently threatened settlements of Telep, Liman and Adice.
