“…The calculation of soil loss was performed using the Erosion Potential Method (EPMGavrilović 1972), which was developed in Serbia and is still in use, mainly in the countries of the former Yugoslavia and the Western Balkans (Zorn & Komac 2008, Tošić et al 2012, Ristić et al 2013), but also in Iran (Tangestani 2006, Bagherzadeh et al 2011. In this study, the level of erosion was assessed based on annual soil loss (Wyear) immediately before afforestation (Wyear0), 10 years after afforestation (Wyear10) and 60 years after afforestation (Wyear60).…”

The selection of tree species can affect the success of afforestation in the rehabilitation of degraded forest sites and forest restoration. In general, black locust (Robinia pseudoacacia L.) and black pine (Pinus nigra Arnold.) represent the most commonly used species in the afforestation of soils that have been degraded by erosion. As far as the extent of the ameliorative effects of black locust and black pine are concerned, it was found that they may play an important role in the selection of species for the afforestation of extremely degraded sites. This study is aimed at determining the potential of black locust and black pine to affect several soil properties, erosion control and C stock, thus creating favourable site conditions for the restoration of previous forest vegetation. This research was conducted in the Grdelica Gorge in south east Serbia, where eight sample plots with an average size of 0.47 ha were established 60 years ago on terrain afforested with black locust and black pine. In each sample plot, we measured the diameter at breast height of all black locust and black pine trees, and the height of 10 black locust and 10 black pine trees in each diameter class. In addition, samples of mineral soil (from depths of 0-5, 5-10 and 10-20 cm) were taken at 4 randomly selected soil profiles in each sample plot, and 8 samples of litter (30 × 30 cm) were also collected. Additionally, laboratory analyses of the physical and chemical properties of the soil and litter were performed in 2 replicates. The obtained results showed that: (1) at the 0-5 cm depth, there was no statistically significant difference in the reaction of the soil solution, although a significant difference in the reaction of the soil solution between the soils under the two species was observed at soil depths greater than 5 cm; (2) there was a significantly higher N content under black locust in the 0-5 cm soil layer; (3) the reduction of soil loss under black locust is statistically significant in all observation periods; (4) black pine is more efficient in C storage. Our results demonstrate that black locust has the potential to improve soil properties and reduce soil loss caused by erosion, while its favourable impact does not decrease over time, making it more suitable for afforestation on degraded land in the examined area.

“…Tangestani [30] compared the Gavrilović and PSIAC model outputs and established that the PSIAC model is more reliable for determining the areas of very high erosion potential. A visual field overview with GPS confirmed a good estimation for areas of moderate and heavy erosion with the Gavrilović method, and a poorer accuracy for areas with slight erosion potential.…”

“…At the Bregalnica basin, Republic of Macedonia [19,20], a very good correspondence was obtained between the results obtained using the Gavrilović method and onsite measurements. Haghizadeh et al [21] and Tangestani [30] used a comparison of model output results with field observations and a GLASGOD (Global Assessment of Soil Degradation) map as a verification method. Bagherzadeh et al [16,17] verified model outputs by a field survey using GPS and a visual comparison of areas characterised as areas with moderate and heavy annual sediment yields.…”

A detailed review of application of the Gavrilović method (Erosion Potential Method) and its modifications, with a focus on the potential surface erosion, is presented in the paper, together with the guidelines and recommendations for future analysis and research as needed for physical planning and urban development. The Gavrilović method results are based on the source of information, expert experience, accuracy, and level of detail of the model input and output data. For further analysis, the authors propose investigation of additional sources of erosion materials, such as construction plots in expanding urban areas. Pregled primjene Gavrilovićeve metode (metoda potencijala erozije) U ovome radu dan je detaljan pregled primjene Gavrilovićeve metode i njezinih modifikacija, s fokusom na potencijalnu površinsku eroziju, kao i smjernice te preporuke za buduće analize i istraživanja neophodna za prostorno planiranje i urbani razvoj. Rezultati Gavrilovićeve metode uvjetovani su izvorom informacija, iskustvom stručnjaka, točnošću i razinom detalja ulaza i izlaza iz modela. Za buduće analize autori predlažu da se u obzir uzmu dodatni izvori erozijskog nanosa poput gradilišta u područjima urbanog razvoja.

Destroying of forest lands and landuse changes have caused undesirable effects in the watershed hydrologic conditions. Landuse and vegetation are important factors in soil erosion and runoff generation. This research has been done using a runoff-rainfall model, sediment-erosion model, Geographical Information System and remote sensing to determine the hydrologic effects of deforestation on Kasilian watershed (north of Iran). A runoff-rainfall model has been presented using GIS (HEC-GeoHMS extension) and hydrologic model (HEC-HMS). The SCS method has been used for presenting the hydrologic model. It is to note that the optimized model is evaluated by other six events of floods. Then, the optimized model has been validated. Erosion potential method model has been applied in GIS environment to simulate soil erosion and sediment rate. According to the obtained results, the runoff and sediment generation potential have been increased in the Kasilian watershed due to deforestation during the last forty years.
