Factors of flooding the territory of the municipality of Obrenovac

Abstract

Frequent floods in the area of the municipality of Obrenovac have initiated the establishing, classification and analysis of the starting factors of their genesis in this area. After the dam had been constructed on the right bank of the Sava River (in the 80’s of the 20th century) along the northern border of the municipality of Obrenovac, there were no more floods in this part of the area caused by its overflows. Recent floods have still been caused by a very frequent flooding of the River Kolubara near Poljana, even several times during the year. For that reason the factors of flooding the Kolubara River from its riverbed have been analyzed in this paper. Except the pluviometric and hydrological regime analysis as direct factors of flooding the indirect causes have also been analyzed in details, the most important of which are: the morphological characteristics of terrain, balance of deposits and anthropogenic impacts. Perceiving the causes of flooding, the conditions for analysis of undertaken measures and giving the possible solutions for their prevention have also been realized. The results of this research can be used in making the strategy for solving the existing waterpower problems of this area.

Česta pojava poplava na prostoru opštine Obrenovac inicirala je utvrđivanje klasifikaciju i analizu odredišnih faktora njihove geneze na ovom prostoru. Nakon izgradnje nasipa na desnoj obali Save (80-tih godina 20. veka) duž severne granice opštine Obrenovac, nisu se više dešavala plavljenja ovog prostora njenim izlivanjima. Recentna plavljenja su i dalje uslovljena veoma čestim izlivanjima reke Kolubare kod Poljana, čak i više puta u toku godine. Iz tog razloga, u ovom radu su analizirani faktori izlivanja Kolubare iz korita. Osim analize pluviometrijskog i hidrološkog režima, kao direktnih faktora nastanka poplava, detaljno su analizirani i indirektni uzroci, od kojih su najvažniji morfološke odlike terena, bilans nanosa i antropogeni uticaji. Sagledavanjem uzroka nastanka poplava ostvareni su i uslovi za analizu preduzetih mera i iznošenje mogućih rešenja za njihovo sprečavanje. Rezultati ovog istraživanja mogu se iskoristiti pri izradi strategije rešavanja postojećih vodoprivrednih problema ovog prostora.
