AB  - The aim of this paper is to show the real impact of vegetation types on runoff, expressed by a mathematical model. Better understanding of this relationship may significantly contribute to the prevention of extreme natural processes that are more and more frequent in the world in recent years. Particular attention to this problem has been paid after the historic flooding that occurred in Serbia in May 2014, taking away many lives, property and starting up numerous erosive processes. In this work multiple linear regression was used to make an estimation of the mean annual, maximum and minimum river runoff in Serbia for the period of 1998-2009. The sample analyzed consisted of 40 small river basins with natural runoff and the independent variables used were mean annual precipitation, mean annual air temperature, basin altitude, the humidity index, basin area, average basin slope, and vegetation factors separated in 8 categories. It was shown that vegetation has an important role in runoff regulation and that it is justified to classify it particularly into three categories: forests, meadows and agriculture. A total of 33 models were formed with R-2  gt  0.8 and runoff changes from 0.1% to 1% within 1% changes to vegetation, depending on type.

AB  - Riverine and torrential floods are the most significant natural hazards on the territory of Serbia. The potentially flooded area in Serbia with a 100-year return period is 15,198.07 km2 (17.2% of total area). Serbia is mostly threatened by the floods of small to medium-size torrential rivers mostly in late spring (from May to the end of June), a period characterised by intensive rainfalls of a few-hour duration. In the Pcinja River Basin, the town of Trgoviste was struck by a flood in May 2010. Two people were killed, almost 170 ha of land and 27 buildings were flooded (including 12 severely damaged), roads damaged or blocked, and 230 inhabitants evacuated. The flood in the Kolubara River Basin of late June 2010 affected 500 ha with 230 flooded households. Total damage was estimated at €370,000. In the watersheds studied, the 2010 floods were natural occurrences, but human action significantly aggravated the disasters. The messages to be learned help improve the system of prevention and the organisation of mitigation of flood damages, in order to reduce it to an acceptable level.

AB  - The territory of Serbia is vulnerable to various types of natural hazards and the risk is not equal across the entire territory, it varies depending on the type of hazard and the expected potential for damage. The first aim of this research was to determine the geographical distributions of the major types of natural hazards. Seismic hazards, landslides, rock falls, floods, torrential floods, excessive erosion, droughts and forest fires are the most significant natural hazards within the territory of Serbia. Areas vulnerable to some of these natural hazards were singled out using analytical maps; their area relative to the total area of Serbia was defined, along with the total surface area that is vulnerable to each type of natural hazard. Upper intensity values for single natural hazards were measured; these values represent the limiting factor for land-use planning at the given level. Based on these analyses, an integral map of the natural hazards of the territory was created using multi-hazard assessment. Hence, a recent state of the natural hazard vulnerabilities of the territory of Serbia was created and then an integral map was made. The integral map showed spatial distribution of the different types of hazards that are considered to be limiting factors for the highest level of land-use planning. The results presented in this article are the first mufti-hazard assessment and the fast version of the integral map of natural hazards distribution in Serbia for land-use planning, which is important both nationally and regionally.

AB  - Construction or improvement of Serbian ski resorts produced numerous negative effects to surrounding environment, endangering even the functionality of the built objects. Investigation involved the analysis of disturbing activities by phases, and consequential environmental impacts. Clear cuttings, trunk transport, machine grading of slopes, huge excavations, and access road construction, caused the strongest pressure to the environment. Follow up activities during skiing and non skiing periods: skiing, usage of snow groomers, moving of vehicles and tourists, forestry activities and overgrazing. Consequential environmental impacts are clearly noticeable through intensive erosion processes, changes of hydrological conditions and forest fragmentation. The most affected ski runs were surveyed (scale 1:1000), all damages were mapped and classified during the summers of 2007-2010. Development of rills and gullies was measured at experimental plots (100x60 m), integrating survey data into GIS application. Changes of hydrological conditions were estimated on computations of maximal discharges before and after the construction of ski resorts, as well as using,local hydrological records. Forest fragmentation is studied on the basis of detailed survey and field work.

AB  - Torrential floods represent the most frequent phenomenon within the category of 'natural risks' in Serbia. The representative examples are the torrential floods on the experimental watersheds of the rivers Manastirica (June 1996) and Kamišna (May 2007). Hystorical maximal discharges (Qmaxh) were reconstructed by use of 'hydraulics flood traces' method. Computations of maximal discharges (Qmaxc), under hydrological conditions after the restoration of the watersheds, were performed by use of a synthetic unit hydrograph theory and Soil Conservation Service methodology. Area sediment yields and intensity of erosion processes were estimated on the basis of the 'Erosion Potential Method'. The actual state of erosion processes is represented by the coefficients of erosion Z=0.475 (Manastirica) and Z=0.470 (Kamišna). Restoration works have been planned with a view to decreasing yields of erosive material, increasing water infiltration capacity and reducing flood runoff. The planned state of erosion processes is represented by the coefficients of erosion Z=0.343 (Manastirica) and Z=0.385 (Kamišna). The effects of hydrological changes were estimated by the comparison of historical maximal discharges and computed maximal discharges (under the conditions after the planned restoration). The realisation of restoration works will help decrease annual yields of erosive material from Wa=24357 m3 to Wa=16198.0 m3 (Manastirica) and from Wa=19974 m3 to Wa=14434 m3 (Kamišna). The values of historical maximal discharges (QmaxhMan=154.9 m3·s-1; QmaxhKam=76.3 m3·s-1) were significantly decreased after the restoration (QmaxcMan=84.5 m3 ·s-1; QmaxcKam=43.7 m3·s-1), indicating the improvement of hydrological conditions, as a direct consequence of erosion and torrent control works. Integrated management involves biotechnical works on the watershed, technical works on the hydrographic network within a precisely defined administrative and spatial framework in order to achieve maximum security for people and their property and to meet other requirements such as: environmental protection, sustainable soil usage, drinking water supply, rural development, biodiversity sustaining, etc. The lowest and the most effective level is attained through PAERs (Plans for announcement of erosive regions) and PPTFs (Plans for protection from torrential floods), with HZs (Hazard zones) and TAs (Threatened areas) mapping on the basis of spatial analysis of important factors in torrential floods formation. Solutions defined through PAERs and PPTFs must be integrated into Spatial Plans at local and regional levels.
