| Summary: | 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/km2), 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. |
