Gis application in analysis of erosion intensity in the Vlasina River Basin

Abstract

This paper analyses the state of erosion intensity in the Vlasina River Basin, the right tributary of the Južna Morava River. To determine the erosion intensity (Z) and sediment production, the Gavrilović method was used, in combination with the bare-soil index (BSI), with the application of geographic information systems (GIS) and multispectral satellite imagery. An erosion coefficient of 0.31 has been identified in the territory of the Vlasina River Basin, which has an area of 1,061.72 km². The prominent vertical fragmentation of the relief, large amount of precipitation in the source parts, density of the river network (1.65 km/km 2), which is above the average river network density in Serbia, as well as inadequate land exploitation, are the main reasons why it is necessary to monitor the erosion intensity in the Vlasina River Basin. The annual production of the sediment is 462,496.30 m³, while the value of specific sediment production is 435,47 m³/km²/year. This study represents the attempt to apply modern technologies to d1etermine the intensity of erosion in the Vlasina River Basin, and the results obtained could be used for more adequate management of land and water resources, sustainable planning of the forest ecosystems and environmental protection.

“…Due to the fact that the increase of the frequency and intensity of natural disasters poses a great danger to humanity (Blaikie et al, 2014), the preparedness of a community can affect the level of expected consequences (Lukić et al, 2013(Lukić et al, , 2016(Lukić et al, , 2017(Lukić et al, , 2018a(Lukić et al, , 2018bDurlević et al, 2019). Due to the specific geographical position and natural conditions (diversity of geological, pedological, hydrological, relief and climatological conditions), Serbia often faces different natural disasters.…”

“…Hence, natural hazards do not pose the greatest threat to humanity (Blaikie et al 2014), but, depending on the magnitude of their impact and consequences, can affect an area to a greater or lesser extent (e.g. Lukić et al 2013Lukić et al , 2016Lukić et al , 2017Lukić et al , 2018aLukić et al 2018b;Durlević et al 2019).…”
