compact city, urban space, suburban space, Olomouc

Development of urban and suburban space in post-socialist countries became extremely dynamic after 1989. It involved the physical structures of cities, social and economic structures, as well as the mobility between cities and hinterlands. Suburbanization was an especially intensive proces when residential suburbanization became the subject of research by social, economic and regional-geographical scientific disciplines. Applied research methods often coincide with technical sciences (urbanism and architecture) because of their mathematical or quantitative nature. The principal objective of this paper is to point to selected approaches to the issue of a city, urbanization and suburbanization. A proper approach to the delimitation of the city (a concept of the compact city exemplified by the city of Olomouc), as well as the delimitation of urban and suburban spaces of this city including the typology of suburban space is presented. The aim is to distinguish different types of city spaces and the hinterland based on the real processes, which take place, operate in the space and reflect it. Hence, an analysis of the urban and suburban space of Olomouc, particularly the potential and real interactions indicating suburbanizing processes is also part of this paper.

channel changes, extreme floods, pattern, indices, braided-wandering river, the River Belá

The paper deals with the braided-wandering type of channel organization. The river reach of the River Belá (1,7 km long) situated in the north of Slovakia has been analysed in order to comprehend its evolutionary trend. Historical maps and aerial photos (1837-2009, nine time horizons) with comparable discharge conditions have been used for the pattern investigation in the ArcGIS. The braided as well as migration indices have served as main tools for the assessment of changes in braided pattern. From 2003 until 2009 the number of islands increased by a third but the number of bars decreased by half. In spite of higher channel water levels during the time of imagining in 2001 and 2008, the decrease of the braiding index value by a half was observed. The notable decrease of the migration index does not correspond to the increasing trend of the number of islands. The decreasing trend of the erosion corridor shows the long term degradation of the river system as is reflected by changes such as the channel straightening or the increase in the area of islands. The present status could be considered as the near-threshold behaviour of the dynamic metastable equilibrium river system.

natural hazards, Western Carpathians, synthetics evaluation, morphological-morphometrical landform types

A spatial synthesis of selected natural hazards (seismic, landslide, snow avalanche, water erosion, flooding and specific karst hazards) in the Western Carpathians is the aim of this article. The total hazard value, probability of cumulative effect formation and dominant genetic type of hazards were used as classification criteria for the regionalization. In line with the synthetic evaluation of natural hazards of Slovakia (Minár et al. 2006 and 2009) an object-based approach was selected. Original morphological-morphometrical landform types were used as elementary units. Differences between the final regionalization and the result of Minár et al. 2006 arose from different definitions of areas (natural unit vs. administrative region), different primary segmentation of area and different input database for the evaluation. However, they are not essential. Similarity of regionalization and their morphotectonic interpretability suggests that the results may reflect objective features of the specific hazardous regions of the Western Carpathians area.

inner periphery, human capital, social capital, potential for development, Czechia

The author makes an attempt to assess the developmental potential of the inner peripheries in Czechia. Attention is given to the quality of human and social capital as integral parts of developmental potential. The first part of the paper focuses on the discussion of selected theoretical and methodological issues surrounding the peripheral areas as well as developmental potential of the human and social capital. The following part describes the employed methods and delimitation of the model areas. In the third section, the developmental potential of three microregions that represent an area of inner periphery of the Central Bohemian Region is evaluated by presentation of selected results of an extensive empirical study carried out in typologically different peripheral microregions of Czechia.
