AB  - Erosion is a significant environmental challenge in Serbia, shaped by natural
and human factors. Pronounced relief, fragile geological substrate, a developed hydrographic network, and a climate characterized by an uneven distribution of precipitation
throughout the year make this area prone to activating erosion processes and flash floods
whenever there is a significant disruption in ecological balance, whether due to the removal
of vegetation cover or inadequate land use. Researchers have recorded approximately
11,500 torrents in Serbia, most of which were activated during the 19th century, a period of
significant social and political change, as well as intensive deforestation and the irrational
exploitation of natural resources. By the mid-19th century, the effects of land degradation
were impossible to ignore. As the adequate assessment of soil erosion intensity is the
initial step in developing a prevention and protection strategy and the type and scope of
anti-erosion works and measures, this article presents the path that the anti-erosion field in
Serbia has taken from the initial observations of erosion processes through the first attempts
to create the Barren Land Cadastre and Torrent Cadastre to the creation of the Erosion
Potential Method (EPM) and its modification by Dr. Lazarevi´c that resulted in the creation
of the first Erosion Map of SR Serbia in 1971 (published in 1983). In 2020, a new Erosion
Map of Serbia was created with the application of Geographic Information System (GIS)
technologies and based on the original method by Professor Slobodan Gavrilovi´c—the
EPM—without the modifications introduced by Lazarevi´c. We compared the 1983 and 2020
erosion maps in a GIS environment, where the change in soil erosion categories was analyzed using a confusion matrix. The updated erosion maps mirror the shift in methodology
from a traditional approach (Lazarevi´c’s modification) to the modern GIS-based method
(Gavrilovi´c’s original EPM) and reflect technological improvements and changes in land
use, conservation practices, and environmental awareness.

AB  - Global warming and climate change cause large temperature oscillations and uneven annual rainfall patterns. The rainy cycles characterized by frequent high-intensity rainfall in the area of the Stubo-Rovni water reservoir, which in 2014 peaked at 129 mm of water in 24 h (the City of Valjevo, the Republic of Serbia), caused major floods in the wider area. Such extremes negatively affect erosion processes, sediment production, and the occurrence of flash floods. The erosion coefficient before the construction of the water reservoir was Zm = 0.40, while the specific sediment production was about 916.49 m3 center dot km-2 center dot year-1. A hydrological study at the profile near the confluence of the Jadar and Obnica rivers, i.e., the beginning of the Kolubara river, the right tributary of the Sava (in the Danube river basin), indicates that the natural riverbed can accommodate flows with a 20% to 50% probability of occurrence (about 94 m3/s), while centennial flows of about 218 m3/s exceed the capacities of the natural riverbed of the Jadar river, causing flooding of the terrain and increasing risks to the safety of the population and property. The paper presents the impacts of the man-made Stubo-Rovni water reservoir on the catchment area and land use as the primary condition for preventing erosion processes (specific sediment production has decreased by about 20%, the forest cover increased by about 25%, and barren land decreased by 90%). Moreover, planned and controlled management of the Stubo-Rovni reservoir has significantly influenced the downstream flow, reducing the risks of flash floods.

AB  - Soil erosion represents a complex ecological issue that is present on a global level, with negative consequences for environmental quality, the conservation and availability of natural resources, population safety, and material security, both in rural and urban areas. To mitigate the harmful effects of soil erosion, a soil erosion map can be created. Broadly applied in the Balkan Peninsula region (Serbia, Bosnia and Herzegovina, Croatia, Slovenia, Montenegro, North Macedonia, Romania, Bulgaria, and Greece), the Erosion Potential Method (EPM) is an empirical erosion model that is widely applied in the process of creating soil erosion maps. In this study, an innovation in the process of the identification and mapping of erosion processes was made, creating a coefficient of the types and extent of erosion and slumps (phi), representing one of the most sensitive parameters in the EPM. The process of creating the coefficient (phi) consisted of applying remote sensing methods and satellite images from a Landsat mission. The research area for which the satellite images were obtained and thematic maps of erosion processes (coefficient phi) were created is the area of the Federation of Bosnia and Herzegovina and the Br & ccaron;ko District (situated in Bosnia and Herzegovina). The Google Earth Engine (GEE) platform was employed to process and retrieve Landsat 7 Enhanced Thematic Mapper plus (ETM+) and Landsat 8 Operational Land Imager and Thermal Infrared Sensor (OLI/TIRS) satellite imagery over a period of ten years (from 1 January 2010 to 31 December 2020). The mapping and identification of erosion processes were performed based on the Bare Soil Index (BSI) and by applying the equation for fractional bare soil cover. The spatial-temporal distribution of fractional bare soil cover enabled the definition of coefficient (phi) values in the field. An accuracy assessment was conducted based on 190 reference samples from the field using a confusion matrix, overall accuracy (OA), user accuracy (UA), producer accuracy (PA), and the Kappa statistic. Using the confusion matrix, an OA of 85.79% was obtained, while UA ranged from 33% to 100%, and PA ranged from 50% to 100%. Applying the Kappa statistic, an accuracy of 0.82 was obtained, indicating a high level of accuracy. The availability of a time series of multispectral satellite images for each month is a crucial element in monitoring the occurrence of erosion processes of various types (surface, mixed, and deep) in the field. Additionally, it contributes significantly to decision-making, strategies, and plans in the domain of erosion control work, the development of plans for identifying erosion-prone areas, plans for defense against torrential floods, and the creation of soil erosion maps at local, regional, and national levels.

AB  - Climate change has a direct impact on flash floods, and indirectly on the environment, society, and economy, due to the rapid development and difficulty of predicting this hydrological phenomenon. The main objective of this study is to assess the potential flash flood hazard areas in the Likodra watershed (218.62 km(2)), one of the most vulnerable parts to flash floods in Serbia, using the flash flood potential index (FFPI) and analytic hierarchy process (AHP) method. Recurring events from 1995 to this day and the devastating impact on settlements of the analyzed area show that this territory is extremely vulnerable. The data used include hydrological statistics (maximum daily rainfall) and spatial data on watershed geographical characteristics (slope, soils, land use, vegetation, drainage density) obtained or derived from various sources (maps, satellite images, digital databases) which were integrated into the GIS environment. The results indicate a severe flash flood hazard level, with high flash flood susceptibility classes occupying 76.20%, 87.78%, and 91.73% of the area, depending on the considered criteria and weights assigned to them.

AB  - Soil erosion is a complex environmental problem of natural and anthropogenically induced origin, which is present on a global scale, with negative consequences for environmental quality, conservation and availability of natural resources, population safety and material security, both in rural and urban areas. Accelerated population growth and the expansion of urban areas lead to marked changes in the purpose and structure of land cover, due to the transformation of both agricultural and forest areas, and natural and close-to-nature areas into non-porous areas. Due to the effects of these mostly spontaneous processes, modern cities as generators of change are "open laboratories" for detecting global trends, but also for finding modalities to mitigate them. A representative example of such a spatial process can be observed in the urban landscape of Belgrade, i.e. the territory for which the Master Plan (MP) is produced, on an area of 778,54 km2 . The MP is the basic spatial-planning and urban instrument for the realization of the concept of sustainable development of the Belgrade area, through a system of guidelines that define the concept of development, regulation and protection of the city. In the modern context, the implementation of solutions envisaged by the MP implies the use of representative databases on current and forecasted erosion processes in terms of spatial distribution and intensity. In this research, the analysis was performed for two time sections (2001 and 2019), while one of the basic indicators is the state of the land cover structure in 2001, with the analysis of climate indicators for the period 1971-2001. In addition, an analysis of the state of land cover in 2019 was performed, using the RCP8.5 climate scenario expected for the middle of the 21st century (2046- 2065). Three empirical erosion models have been applied: the Erosion Potential Method (EPM), the Revised Universal Soil Loss Equation (RUSLE) and Geoland 2 (G2). The implementation of erosion models was performed using modern methodology in urban conditions with the application of different climate scenarios through the quantification of change dynamics in the surface structure. The related results are applicable in the process of drafting planning documents and creating solutions to control and mitigate the effects of destructive erosion processes, fast surface runoff and the occurrence of torrential floods.

U okviru ovog rada, analiza je obavljena za dva vremenska preseka (2001. i 2019. godina), gde je jedan od osnovnih pokazatelja stanje strukture zemljišnog pokrivača u 2001. godini, uz analizu klimatskih pokazatelja za period od 1971. do 2001. godine. Takođe, obavljena je analiza stanja zemljišnog pokrivača u 2019. godini, uz korišćenje RCP8.5 klimatskog scenarija koji je očekivan za sredinu XXI veka (2046-2065. godina). Primenjena su tri empirijska eroziona modela: Metod Potencijala erozije (MPE), Revidirana univerzalna jednačina za proračun gubitka zemljišta (Revised Universal Soil Loss Equation–RUSLE) i Geoland 2 (G2). Implementacija erozionih modela u urbanim uslovima, uz primenu različitih klimatskih scenarija, kroz kvantifikaciju dinamike promena strukture površina, obavljena je primenom savremene metodologije, sa rezultatima koji su aplikativni u procesu izrade planskih dokumenata i kreiranju rešenja za kontrolu i ublažavanje efekata delovanja destruktivnih erozionih procesa, brzog površinskog oticaja i pojave bujičnih poplava., Soil erosion is a complex environmental problem of natural and anthropogenically induced origin, which is present on a global scale, with negative consequences for environmental quality, conservation and availability of natural resources, population safety and material security, both in rural and urban areas. Accelerated population growth and the expansion of urban areas lead to marked changes in the purpose and structure of land cover, due to the transformation of both agricultural and forest areas, and natural and close-to-nature areas into non-porous areas. Due to the effects of these mostly spontaneous processes, modern cities as generators of change are "open laboratories" for detecting global trends, but also for finding modalities to mitigate them. A representative example of such a spatial process can be observed in the urban landscape of Belgrade, i.e. the territory for which the Master Plan (MP) is produced, on an area of 778,54 km2 . The MP is the basic spatial-planning and urban instrument for the realization of the concept of sustainable development of the Belgrade area, through a system of guidelines that define the concept of development, regulation and protection of the city. In the modern context, the implementation of solutions envisaged by the MP implies the use of representative databases on current and forecasted erosion processes in terms of spatial distribution and intensity. In this research, the analysis was performed for two time sections (2001 and 2019), while one of the basic indicators is the state of the land cover structure in 2001, with the analysis of climate indicators for the period 1971-2001. In addition, an analysis of the state of land cover in 2019 was performed, using the RCP8.5 climate scenario expected for the middle of the 21st century (2046- 2065). Three empirical erosion models have been applied: the Erosion Potential Method (EPM), the Revised Universal Soil Loss Equation (RUSLE) and Geoland 2 (G2). The implementation of erosion models was performed using modern methodology in urban conditions with the application of different climate scenarios through the quantification of change dynamics in the surface structure. The related results are applicable in the process of drafting planning documents and creating solutions to control and mitigate the effects of destructive erosion processes, fast surface runoff and the occurrence of torrential floods.",

AB  - Land degradation caused by erosion processes is a widespread global problem. Rain simulators are one of the tools often used to determine the resistance of soils to erosion processes. The aim of this publication is to present the process of the construction and calibration of a small, portable field simulator which would be implemented in research studies designed to determine the changes in the soils' shear strength parameters in forested areas (in situ) caused by a change in soil moisture content achieved by the rain simulation. The constructed simulator consists of a metal frame, sprayers (with specific nozzles), a sediment funnel/tray made of metal, water and a sediment collector unit, a water tank and pump, and a set of rubber hoses, manometer, valves, reducers, adapters and other supplementary equipment. The calibration was carried out by using the pluviometric method. The choice of nozzles was based on the criteria of low water consumption (losses), the Christiansen uniformity coefficient (CU) and the possibility of achieving specific downpour intensities for the investigated area. The further calibration of the device consisted of determining the raindrop diameter and the distribution of the rainfall when the simulator is positioned on the slopes (7 degrees and 15 degrees). The achieved rain intensity was 1.7-1.9 mm/min, with a CU of 92.23-93.70% for the raindrop diameters (D-50) equal to 1.2 mm. The kinetic energy of the simulated rain (Ke) was 2.82.10(-6) J. The constructed simulator proved itself to be in accordance with all of the given criteria, and it can successfully be implemented in research studies aimed at determining the resistance of forest soils to erosion processes, infiltration, and sediment yield.

AB  - In this paper, Soil Protection Coefficient (Xa) was quantified through the approach of high resolution multispectral orthomosaic segmentation and classification. The approach was presented in the example of ski lane in ski center Kopaonik. The data collection was performed through application of Unmanned Aerial System equipped with 5band multispectral sensor and RGB sensor. Data processing was performed with digital photogrammetric and Object Based Image Analyses software. The Soil Protection Coefficient represents the descriptive and very sensitive parameter of Erosion Potential Method. Application of 5 spectral bands, of which 2 bands are very sensitive to the type of land use /land cover allowed precise detection, delineation and classification of different land cover/use types. These types were directly tied to the values of Xa coefficient which were originally proposed by the author of the Erosion Potential Method, professor Slobodan Gavrilović. The final result was a georeferenced digital map classified with both land cover/use and Xa values classes. This approach created the potential to use such maps for further analyses, planning, and modeling of erosion protection measures.

AB  - Soil degradation process reduce the ability of the land to perform its primary function food production. The most aggressive process being soil erosion, endangers the environment and affects the quality of life. The constant loss of arable land by soil sealing, due to urban expansion, is affecting agricultural production. As a result, the conditions for food production are limited, and the economic prosperity of that area is disputable. This paper represents an analysis of the land use and its change detected by Corine Land Cover (CLC) and the assessment of soil erosion rate and its spatial distribution using Revised Universal Soil Loss Equation (RUSLE) model through a GIS-based approach, for two periods (2000, 2018) in Belgrade suburban area. This study area, characterized by many agricultural areas concentrated around the capital of the Republic of Serbia, is attractive from the economic point of view due to the proximity of the market. The results indicate that with the constant increase of inhabitants, agricultural areas have been reduced due to urban sprawl. The average annual soil loss decreased from 5.85 to 1.95 t/ha"year. Analysis shows that the high medium erosion rate that was detected in the study area in 2000. decreased by 65% compared to the results from 2018, while the processes of low erosion rate has increased by 20%. Despite all the soil loss detected in the study area, soil sealing is the most harmful process of soil degradation due to its often implication of the complete loss of biological functions.

AB  - Soil erosion is a global problem that negatively affects the quality of the environment, the availability of natural resources, as well as the safety of inhabitants. Soil erosion threatens the functioning of urban areas, which was the reason for choosing the territory of the Master Plan of Belgrade (Serbia) as the research area. The calculation of soil erosion loss was analyzed using the G2 erosion model. The model belongs to a group of empirical models and is based on the synthesis of the equation from the Revised Universal Soil Loss Equation (RUSLE) and the Erosion Potential Method (EPM). The estimation of soil degradation was analyzed in two time periods (2001 and 2019), which represent the time boundaries of the management of the Master Plan of Belgrade. The novel approach used in this research is based on using the land cover inventory as a dynamic indicator of the urbanization process. Land cover was identified using remote sensing, machine learning techniques, and the random forest algorithm applied to multispectral satellite images of the Landsat mission in combination with spectral indices. Climatic parameters were analyzed on the basis of data from meteorological stations (first scenario, i.e., 2001), as well as on simulations of changes based on climate scenario RCP8.5 (representative concentration pathways) concerning the current condition of the land cover (second scenario). A comparative analysis of the two time periods identified a slight reduction in total soil loss. For the first period, the average soil loss value is 4.11 t center dot ha(-1)center dot y(-1). The analysis of the second period revealed an average value of 3.63 t center dot ha(-1)center dot y(-1). However, the increase in non-porous surfaces has led to a change in the focus of soil degradation. Increased average soil loss as one of the catalysts of torrential flood frequencies registered on natural and semi-natural areas were 43.29% and 16.14%, respectively. These results are a significant contribution to the study of soil erosion in urban conditions under the impact of climate change.

AB  - Small run-of-river hydropower plants (RRHPs) have revealed strong harmful effects worldwide on stream habitats (e.g., fragmentation and destruction) and decreased fish species, especially anadromous species abundance. Recently, RRHPs have rapidly been installed in Serbia. Most were installed on montane streams because their steep slopes are most convenient for hydropower energy production at minimal costs. Brown trout Salmo trutta are prominent in the fish communities of this rarest type of aquatic ecosystems. Their native molecular diversity reflects a biodiversity hotspot in the Balkans, and they provide attractive fishing opportunities. Records from fishery management plans for highland stream fisheries where RRHPs were installed revealed reduced brown trout biomass compared with streams without RRHPs.

abstract = "Small run-of-river hydropower plants (RRHPs) have revealed strong harmful effects worldwide on stream habitats (e.g., fragmentation and destruction) and decreased fish species, especially anadromous species abundance. Recently, RRHPs have rapidly been installed in Serbia. Most were installed on montane streams because their steep slopes are most convenient for hydropower energy production at minimal costs. Brown trout Salmo trutta are prominent in the fish communities of this rarest type of aquatic ecosystems. Their native molecular diversity reflects a biodiversity hotspot in the Balkans, and they provide attractive fishing opportunities. Records from fishery management plans for highland stream fisheries where RRHPs were installed revealed reduced brown trout biomass compared with streams without RRHPs. Research on six streams with operational RRHPs revealed severe deterioration of habitat, for example, increased water temperature, reduced dissolved oxygen, and increased nutrient contents. Effects on fish communities were evident from a change in their structure.

AB  - Check dams are built to control erosion processes and torrential floods. In Serbia, legally binding documents, VOS (2002) and PPRS (2010), provide the concept for the water supply of the population and industry by regional systems for which water is provided by building high dams and formation of reservoirs. With this concept, it is often not possible to meet the needs of local communities in mountainous areas. In order to contribute to solving the water supply problems of these mostly poor villages, research was conducted on the possibility of using check dam aggradation groundwater for this purpose. Field investigations and analysis of project documentation for numerous check dams and aggradations in Serbia were carried out. Potential quantities and quality of groundwater in the aggradations were analyzed as a resource for the water supply of the population. The results of the research indicate very favorable possibilities of the aggradations for the accumulation of groundwater in the form of unconfined or phreatic aquifer with a free water table, in quantities that can be used for water supply. It was stated that: 1) under favorable conditions, with check dams on watercourses with constant flow and large-scale aggradations, there is a possibility of accumulating sufficient quantities of groundwater as a resource for water supply, 2) improving the quality of infiltrated waters by the process of filtration through intergranular porous media of the aggradation, and reaching the level of water supply quality, and 3) favorable economic parameters for opening the source at the aggradation, compared to other types of water sources. The possibility that check dams, in addition to their traditional role, could be used for local water supply facilities was also highlighted.

AB  - U skladu sa Nacionalnim akcionim planom za proizvodnju energije iz obnovljivih izvora u Srbiji je do sada izgraĊeno oko 90 malih hidroelektrana (MHE), dok je planirana izgradnja 850 MHE, dominantno derivacionog tipa, u brdsko-planinskim podruĉjima Srbije, uglavnom, u zaštićenim prirodnim podruĉjima (Nacionalni parkovi, Parkovi prirode, Specijalni rezervati prirode). Srbija je najsiromašnija zemlja Balkana kada su u pitanju autohtone površinske vode, a upravo na ekološki i hidrološki najvrednijim reĉicama zapoĉelo je sprovoĊenje masovne gradnje MHE. Problemi koji su uoĉeni izgradnjom postojećih MHE zahtevaju hitno preispitivanje procedura za izdavanje dozvola, kako za planirane tako i izgraĊene objekte, uz imperativ zabrane dalje gradnje u zaštićenim podruĉjima. Ukoliko bi se sve planirane MHE izgradile, bilo bi obezbeĊeno svega 2-3,5% potreba u energetskom bilansu Srbije na godišnjem nivou, ali bi to znaĉilo da je devastiran najveći deo kvalitetnih vodotokova brdskoplaninskog regiona Srbije. Zbog malog energetskog doprinosa, a fatalnih ekoloških posledica, vlasti u SAD su uklonile više od 1.000 MHE, u periodu 1993-2017.

AB  - In accordance with the National Renewable Energy Action Plan of the Republic of Serbia, approximately 90 small hydro-power plants (SHPP) is constructed so far, and the construction of 850 SHPP, predominantly of derivation type, is planned, in mountainous parts of Serbia, mainly in the protected areas (National parks, Nature parks, Special Nature Reserves). Serbia is the poorest country in the Balkans when it comes to autochthonous surface waters, and that is exactly where the massive construction of SHPP has begun. Problems noted by the construction of existing SHPPs require urgent reassessing of procedures for issuing licenses, both for planned and existing facilities, with the imperative of prohibiting further constructions in the protected areas. Construction of all planned SHPPs, would provide only 2-3,5% of the needs in the energy balance of Serbia. It means that largest part of the high quality watercourses of the hilly-mountainous region of Serbia should be devastated. Due to the small energy contribution and the fatal environmental consequences, the authorities in the US have removed more than 1.000 SHPPs in the period 1993-2017. Similar processes are taking place in France, Spain, Germany, and Sweden. Other ways of producing energy from renewable sources have lower impact on environment, and if the losses of Electric Power Management Company of Serbia, during the transmission of electricity would decrease by only 2%, a quantity of saved energy would eliminate the need for derivative SHPPs.

AB  - Background and Purpose: Although natural hazards cannot be prevented, a better understanding of the processes and scientific methodologies for their prediction can help mitigate their impact. Torrential floods, as one of the consequential forms of the existing erosion processes in synergy with extremely high precipitation, are the most frequent natural hazard at the regional level, which was confirmed by the catastrophic events in May 2014 when huge territories of Serbia, Bosnia and Herzegovina and Croatia were flood-struck. The basic input data for the design of protective structures in torrential beds and watershed slopes are the values of the maximal discharge, area sediment yields, and sediment transport. The calculation of these values requires a careful approach in accordance with the characteristics of torrential watersheds, such as the steepness of slopes and beds in torrential watersheds, intensive erosion processes, favorable conditions for fast runoff formation and the transport of huge quantities of sediment. Materials and Methods: The calculations of maximal discharges, area sediment yields, and sediment transport in the experimental watershed of the Cadavica River were based on using two different spatial resolutions of digital elevations models (DEMs) - 20 m resolution DEM, with land use determined from aerial photo images, and the 90 m resolution DEM, with land use determined on the basis of the CORINE database. The computation of maximal discharges was performed by applying a method that combined synthetic unit hydrograph (maximum ordinate of unit runoff q(max)) and Soil Conservation Service methodologies (deriving effective rainfall Pe from total precipitation Pb). The computation was performed for AMC III (Antecedent Moisture Conditions III - high content of water in the soil and significantly reduced infiltration capacity). The computations of maximal discharges were done taking into account the regional analysis of lag time, internal daily distribution of precipitation and classification of soil hydrologic groups (for CN - runoff curve number determination). Area sediment yields and the intensity of erosion processes were estimated on the basis of the "Erosion Potential Method". Results and Conclusions: The selected methodology was performed using different input data related to the DEM resolution. The results were illustrated using cartographic and numerical data. Information on relief conditions is a vital parameter for calculating the elements of the environmental conditions through the elements of maximal discharge, area sediment yields and sediment transport. The higher precision of input data of DEM provides a more precise spatial identification and a quantitative estimation of the endangered sites.

AB  - Zemljište predstavlja važan prirodni resurs čije pravilno korišćenje zahteva dobro poznavanje svih endogenih i egzogenih faktora koji uslovljavaju različite vidove njegove degradacije. Erozija je jedan od vidova degradacije zemljišta. Procesi erozije zemljišta se odlikuju izraženom složenošću i faktori koji utiču na njih su dinamični i menjaju se u prostoru i vremenu.

U ovom radu, analiza prostorne i vremenske degradacije prirodnih resursa je vršena na slivu reke Likodre. Reka Likodra se nalazi u severozapadnom delu Republike Srbije i pozicionirana je na području opštine Krupanj. Glavni tok u neposrednoj blizini grada Krupnja nastaje od četiri manja toka koji imaju izražen bujični karakter (Bogoštica sa Kržavom i Čađavica sa Bršticom). Tokom maja 2014. godine gradsko područje, a i ruralni delovi opštine Krupanj su zadesile katastrofalne bujične poplave koje su rezultirale gubitkom ljudskih života kao i ogromnim materijalnim štetama.

AB  - Soil is an important natural resource whose proper use requires a good knowledge of all endogenous and exogenous factors that cause different types of degradation. Erosion is one of the forms of soil degradation. Erosion processes are characterized by a distinctive complexity and the factors affecting them are dynamics and change in space and time. A complex system degradation requires a multidisciplinary approach to the use of modern methods and techniques. Today, a large number of models are available for the assessment of soil loss through erosion as well as the levels of risk from erosion, today. Most of these are based on the logics of GIS thanks to its ability to sublimate heterogeneous information. In this paper, the analysis of spatial and temporal degradation of natural resources is carried out in the Likodra River watershed. The Likodra River is located in the northwestern part of the Republic of Serbia, and is positioned in the municipality of Krupanj. The main stream in the immediate vicinity of the town of Krupanj formed from four small streams that have expressed torrential character (the Bogoštica with the Kržava and the Čađavica with the Brštica). In May 2014, the urban area and rural parts of the municipality Krupanj were affected by catastrophic flash floods that resulted in the loss of human lives and enormous material damage. Soil degradation in the study area was analyzed using the Erosion Potential Method (EPM). The method is characterized by a high degree of reliability for determining the intensity of erosion, calculation of sediment yield and transport. The advantage of this method compared to other methods its lower complexity in terms of quantity of input parameters, simplicity and the possibility of application in GIS. In addition, the method has the advantage of choice, because it was developed in this area. The method is based on the analytical processing of data on factors affecting erosion. As the erosion spatial phenomenon appears on the map according to the classification on the basis of the calculated analytical erosion coefficient (Z), which depends on the characteristics of the soil, vegetation cover, relief and visible degree of erosion. By applying the Erosion Potential Method (EPM) an erosion map has been developed, showing the spatial distribution of erosion processes in the catchment area of the Likodra River watershed. The erosion map provides an insight into the state of erosion processes of different intensity and character. For the study basin, all its visible manifestations are manifested in the medium coefficient of erosion Zsr = 0.204. The current state of erosion was analyzed in comparison with the situation in the original 1983 erosion map of FR Serbia.

Planning and designing activities, with application of technical and biotechnical erosion control structures, through concept of restoration, are necessary measures in protection of ski areas.",
