The catchments of the reservoirs Spilje and Globocica are positioned in the western part of North Macedonia. These catchments are situated in the higher part of the Drim/Drin catchment which is a transboundary catchment stretching in several countries. The two catchments were mapped for erosion according to the Erosion potential method by Gavrilovic. In order to assess the Erosion potential method, a bathymetric survey was also carried out. The two erosion maps created for the two reservoir catchments show very different results. The catchment of the reservoir Globocica is one of the most preserved catchments in the country from soil erosion point of view with average erosion coefficient of 0.21, specific annual production of erosive sediment is 394 m3 km-2 yr-1, the specific annual transport of erosive sediment is 247 m3 km-2 yr-1 and the annual transport of erosive sediment is 74,543 m3yr-1. On the other hand, the catchment of the reservoir Spilje is one of the most erosive areas in the country, with average erosion coefficient of 0.44, specific annual production of erosive sediment of 776 m3 km-2 yr-1, the specific annual transport of erosive sediment of 541 m3 km-2 yr-1 and annual transport of erosive sediment is 563,154 m3yr-1. The sedimentation of both of the reservoirs was measured only once in 2014 and 2015. The accumulated sediment in Spilje is 36.7 x106 m3 or mean annual intensity of sedimentation is 815,555 m3yr-1. On the other hand, the Globocica reservoir has much lower values for sedimentation, 3.3x106 m3 or mean annual intensity of sedimentation of 67,346 m3 yr-1.
