(Erosion Prediction in Ungauged Basins: Integrating Methods and Techniques (Proceedings of Symposium HS01 held during IUGG2003 at Sapporo, July 2003), IAHS Publication No. 279, 2003, pp. 234–240).
A new model was implemented for the quantitative estimation of degradation in the Aliakmon River basin. The empirical model developed by Gavrilovic (1972) served as a starting point and was further extended by initiating appropriate adjustments through the use of a Geographic Information System (GIS). In the case of the Aliakmon River basin, the average annual degradation was estimated with remarkably high precision. Using this improved model, several maps were constructed, including a map of total potential erosion. To our knowledge, this is the first time that such a model has been applied on such a large basin. More importantly, based on our results we feel that this improved model of estimation may be applied to any basin, including high-relief regions and very large basins.
