The Ljuboviđa watershed in Western Serbia with an area of 158 km² is frequently affected by torrential floods, which have devastating effects. The soil characteristics, land use patterns and rugged topography ensure the rapid generation of surface runoff during extreme rainfall events. The main focus of this work is to reconstruct the extreme torre...

The erosion potential model was applied to estimate the soil erosion status of rural settlements during the years 1971 and 2011. We used univariate and bivariate local Moran’s I indices to detect and visualize the spatial clustering of settlements with respect to changes in erosion intensity and agricultural land use, as well as their mutual spatia...

Adequate disposal of municipal solid waste (MSW) is one of Serbia’s most complex environmental challenges. The problem is more serious in urban areas, since large amounts of waste are disposed of in locations that do not comply with environmental, technical, and socio-economic standards. Such is the case for the city of Kraljevo, where about 116,00...

Riverbank erosion and lateral channel migration are important geomorphological processes which cause various landscape, socio-economic, and environmental consequences. Although those processes are present on the territory of Serbia, there is no available data about the soil loss caused by riverbank erosion for the entire country. In this study, the...

Serbia is landlocked country with territory of 88,361 km² primarily draining through the Danube River/Black Sea Basin. The rivers Tisa, Sava and Velika Morava are three significant tributaries flowing into the Danube River on the territory of Serbia. The dominant natural conditions influencing water resources in the country include characteristics...

The main objective of this study is susceptibility assessment to torrential floods in Ukrina River Basin using Index Based Method (IBM) and Flash Flood Potential Method (FFPI), which operates entirely in a GIS environment. The definition and identif...

Despite the fact that the torrential floods and forest fires in this century caused enormous damage to Serbia, there are no cadasters of torrential streams for the most parts of the country, and there were no forest fires susceptibility zonation, whose indirect consequences include the intensification of torrential flooding. Therefore, it is necess...

As of recently, the role of social networks in the disaster risk management process has become significantly important. This is largely due to a huge number of smartphones with installed applications (Facebook, Twitter, etc.) that allow their users to share information in the form of text, images and video. By analyzing and describing the multiple...

In this paper the relationship between demographic and land use changes and their impact on the intensity of erosion processes in the Nišava River basin is examined by using quantitative typology. For the purposes of quantifying the erosion intensity changes, the erosion potential model (EPM) was used to calculate the annual gross erosion and spati...

One of the most vulnerable parts to natural hazards in Serbia is Kolubara river basin. In the past, during the period from 1929 to 2013, 121 torrential flood events in the Kolubara river basin were recorded which show that this territory is extremely vulnerable to the torrential floods. The extreme event which occurred in May 2014 causing the catas...

The fluvial process is characterized by an intense meandering riverbed. The aim of this study was to perform a reconstruction of the lateral migration of a 15 km length of an active meandering river during the period 1930–2016. River morphological changes were analyzed and quantified from cadastral maps and aerial photographs as well as by geodetic...

Torrential floods are a natural hazard which is the most common hazard in Serbia. Torrents and torrential floods occur as a consequence of intensive soil erosion processes in a basin. As a consequence of natural conditions, there are water erosion of various intensities almost on the entire territory of Serbia. According to the torrential cadastre...
