Torrential floods are the most frequent natural catastrophic events in the Republic of Srpska (B&H). The main objective of this study is susceptibility assessment to torrential floods in Ukrina River Basin using Index Based Method (IBM) and Flash Flood Potential Method (FFPI), which operates entirely in a GIS environment. The definition and identification of influencing factors for torrential floods was the first step in the process of developing the Torrential Flood Susceptibility Model (TFSM). According to the results of these models, 54.00% and 40.86% of the Ukrina Basin area is in the categories of strong and very strong susceptibility to torrential floods. The second task was to identify the torrential basins and create the Register and the Cadastre of Torrential Basins in the Ukrina River Basin. After detailed field survey and analyses, 154 torrential basins have been identified, occupying 551.37 km2 of the Ukrina Basin. According to the validation indicators of the Torrential Flood Susceptibility Model, 138 torrential basins are in the category of strong and very strong susceptibility according to Index Based Method, while 112 torrential basins are in the same category of susceptibility according to Flash Flood Potential Index Method, which are very good results of the validation. This paper presents the significant step towards better understanding of the phenomenon of torrential floods in the Republic of Srpska (B&H). The data presented in this paper are also significant to practical issues such as integral water management projects, spatial planning, sustainable land planning and protection of soil, forest ecosystems and environmental protection, sediment management, agriculture and other human activities.

Danilovgrad and the Bjelopavlica Plain belong to the submediterranean zone of the Mediterranean climate region. The aim of this paper was to determine some specific characteristics of the Danilovgrad climate, such as the degree of continentality, aridity and bioclimatic characteristics. Data used in the research cover the period 1955-2011. The results of the study showed the dominance of the continental effect on temperature, while oceanicity was less pronounced. In hygric terms, during most of the year the climate of Danilovgrad is characterized as low humid to perhumid. Moreover, in the period October-March it is very humid, which points to the domination of oceanic influences. During the three summer months, it is dry to very dry. Based on the average monthly values of the equivalent temperature - an indicator of physiological (subjective) feeling of heat, the winter months in Danilovgrad are not assessed as very cold. It is cold in January, and in February and December it is cool. It is fresh in March and November, comfortable in April and October, and warm in May and September. In Danilovgrad, in summer it is overheated and a little muggy. All considered indicators point to quite pronounced oscillations during the year, especially in terms of humidity. Comparing the obtained results with Podgorica, it can be concluded that the climate of Danilovgrad is more continental, a bit colder and wetter.

The paper explores spatial dynamics of the level and the intensity of the concentration of population/settlements situated in the Pomoravlje area, during the post- Second World War period, including overall conditions of the territory and evolutional aspect of its developmental tendencies. By evaluating Census data from 1948-2011, the main focus had been set on population dynamics of the settlements of the Pomoravlje area, and its dependence with regards to geographic, hypsometric and locational aspects of the territory. Considering the population dynamics of settlements in this area, the core concentrations and directions of their movement over the 63-year period were separated. The aim is to determine the degree of territorial homogeneity/heterogeneity of population distribution, using Hoover index of concentration and index of population concentration, both examining the relation between population and the area in question, and Kant index of concentration which next to those, also includes vertical differentiation. Therefore, nucleuses of population concentration as the focal points of settlements? expansion had been formed, as well as the population regression of small, underdeveloped settlements.

The paper focuses on the results of rapid, combined multi-techniques in field measurements influenced by the geological background, which allow the survey of extensive polluted areas and decision support systems. The investigated area (former briquette factory) is highly contaminated by Total Petrol Hydrocarbon-types (TPHs). Heavy metals were investigated with GC-MS, turbidimetric, Raman-spectroscopic method, and with XRF. Qualitative assessment of alkanes, alkenes and alkines as well as aromatic compounds was determined by Raman peak analysis. The areas contaminated with Cr, Zn, Co and carcinogenic hydrocarbons, are in most cases absorbed in the coal powder matrix.

The morphostructural relief of the highest parts of the central Kopaonik Mt was altered by exogenous agents, by denudation as a primary and periglacial processes as a secondary agent. Previous geomorphological studies were mostly focused on the traces of the Pleistocene glaciation, although no reliable evidence was found for this. Recent research, in the part of the mountain above 1,700 m of absolute height, points to geomorphological phenomena resulting from more recent processes within the periglacial environment. By means of geomorphological reconnaissance, analysis and mapping of the highest part of the Kopaonik mountain massif, forms of relief were studied, the ones that according to their morphology correspond to the periglacial forms and processes described in the conditions of high latitudes and high mountains. Determining the spatial coverage of the periglacial belt, especially its lower limit on Kopaonik Mt, is important for understan-ding the distribution of this climatic morphology both in Serbia and in South East Europe. The research contributes to one of the primary aims of exploring the concept of the periglacial zone, in terms of the regional distribution of its specific relief forms.

This paper analyses the state of erosion intensity in the Vlasina River Basin, the right tributary of the Juzna Morava River. To determine the erosion intensity (Z) and sediment production, the Gavrilovic method was used, in combination with the bare-soil index (BSI), with the application of geographic information systems (GIS) and multispectral satellite imagery. An erosion coefficient of 0.31 has been identified in the territory of the Vlasina River Basin, which has an area of 1,061.72 km?. The prominent vertical fragmentation of the relief, large amount of precipitation in the source parts, density of the river network (1.65 km/km2), which is above the average river network density in Serbia, as well as inadequate land exploitation, are the main reasons why it is necessary to monitor the erosion intensity in the Vlasina River Basin. The annual production of the sediment is 462,496.30 m?, while the value of specific sediment production is 435,47 m?/km?/year. This study represents the attempt to apply modern technologies to d1etermine the intensity of erosion in the Vlasina River Basin, and the results obtained could be used for more adequate management of land and water resources, sustainable planning of the forest ecosystems and environmental protection.
本文分析了胡斯那-莫拉瓦河右支流瓦拉西纳河流域的侵蚀强度状况。为了确定侵蚀强度(Z)和产沙量，采用了Gavrilovic方法，结合裸土指数(BSI)，并应用地理信息系统(GIS)和多光谱卫星图像。在面积为1061.72 km的瓦拉西纳河流域，土壤侵蚀系数为0.31。地形垂直破碎化突出、源区降水量大、河网密度(1.65 km/km2)高于塞尔维亚平均河网密度，以及土地开发利用不足，是对Vlasina河流域进行侵蚀强度监测的主要原因。泥沙年产量为462,496.30 m?，比产沙量为435、47 m /km /年。本研究是运用现代技术确定Vlasina河流域侵蚀强度的尝试，所得结果可用于更充分的土地和水资源管理、森林生态系统的可持续规划和环境保护。

In the major theories of economic development, the spatial aspect has often been neglected. Within the evolution of regional development theories, not only is there a shift in focus from exogenous to endogenous factors, but also an increasing importance of human capital in the development process. Agglomeration economies are ultimately driven by savings in transport costs, related not only to the exchange of goods and services, but also to people and ideas. Large cities play crucial role in knowledge spillover because the interaction of educated and creative people stimulates innovation. Also, it is obvious that there is a very pronounced feedback principle between urban growth and the knowledge spillover. Contemporary urbanization trends are perfectly matched with the technological advances of the new age which led to sharp decrease of costs of communication and transfer of information. These processes (that trigger pronounced agglomeration diseconomies, such as pollution, rising cost of living and congestion), accompanied by the demographic explosion that is especially evident in developing countries, bring into focus the problems of urban development.
