How Extreme Were The Torrential Floods In Smaller Watersheds In Serbia In September 2014

Abstract

The September torrential floods in 2014 in the Eastern Serbia were a real disaster for local residents in municipalities of Kladovo, Negotin and Majdanpek. Meteorological extreme event caused the hydrological extreme event which led to declaration of the emergency situation in all three municipalities. The combined method of Soil Conservation Service and synthetic unit triangular hydrograph (SCS-SUH) is employed to compute the maximal discharges in small watersheds of Dupljanska reka and Manastiricki potok, in order to assess the extremeness of September 2014 torrential flood events. Since the surface runoff is accompanied by intensive soil erosion on watershed slopes and the maximal discharges by sediment transport in river beds, estimation of mean annual sediment transport is also presented in this work. The September 2014 floods will remain historic given that they took 5 human lives and caused enormous material damage for local municipalities, so presented hydrological analysis should be taken as very important part of flood event documentation along with reports of municipalities’ emergency headquarters.
