Socio-economic effects of the river system changes in Donja Kolubara River valley

Human impact on a river system and fluvial erosion are often followed by changes in landscape morphology, as well as demographic and socio- economic effects. In order to open a new mine for lignite exploitation, one part of the river Kolubara was diverted into Pestan River in 1976. Pestan riverbed was not predisposed for kinetic energy of a stronger flow which caused more intensive fluvial erosion by digging the riverbanks and higher amounts of silt. Widening of the concave Pestan riverbanks, today’s Kolubara riverbanks, caused loss of land along the parcels which have been exposed to more intensive erosion. The amount of the lost arable land was estimated on the base of comparative analysis of cadastral maps of this area from 1967 and orthophoto images of the actual state of the Kolubara river course. These landscape modifications caused changes in the allocation of land use (former arable land became fallow land), amount of agricultural production and demographic and land property structure. This paper presents an analysis of the effects of human impact and fluvial erosion in the river system.
