landscape evolution, active orogeny, glacial and periglacial processes, Nepal Himalaya

The results of geomorphological analysis of landform patterns in the Makalu – Barun region of the Nepal Himalaya related to morphotectonic features of relief-building processes are presented. High-mountain landforms in the relief section between Mount Everest (8 848 m), Makalu (8 475 m) and the Arun valley (1 350 m) are the result of morphotectonic processes, as well as of denudation and erosional efficiency in different paleoclimatic conditions during the late Cenozoic. Observations in the East Nepal Himalaya also suggest significant feedbacks between the rate of tectonic exhumation of deep crystalline rocks and the intensity of climate-morphogenetic processes. It is suggested that the very high rate of valley incisions also stimulates isostatic compensation, which is one of the factors influencing the uplift of the East Nepal Himalaya during the Quaternary. Extreme exhumation of deep crystalline rocks in the Himalaya during the late Cenozoic is the result of morphotectonic processes, as well as the effective tuning of paleogeographical changes to the extension of the main climate-morphogenetic zones.

river morphology, parameters, survey, assessment, hydromorphological quality

In the last two decades, the management of rivers has developed into the form of a multifunctional procedure built upon the holistic base that unites scientific know-ledge, engineering interventions, control of pollution, water resource management, fisheries, transports, energy economy and protection of rivers. The paper presents a review of basic groups of publications in the field. The methodology of river morphology assessment based on ideas of the role of thresholds in river morphology sensitivity, and stages of aggradation and degradation of channel and floodplain morphology are regarded as principle tendencies of river morphology change. Secondly, the article shows the basic features of the geomorphic assessment framework of rivers. The main principles of the assessment procedure consisting of comparison between the properties of river reach and reference reach conditions are designed. The proposed framework includes guidance on sample site selection, field procedures and the scoring system for the assessment as well as guidance on training, certification and intercalibration procedures. The assessment is based on the principle that the highest quality is obtained when the hydromorphological conditions are as close to the reference situation as possible and when the spatial variation is as large as possible.

flood hazard, flood maps, N-year maximum discharges, digital relief model, 1D hydraulic model, HEC-GeoRAS

The aim of the paper is to analyse the basic methodological questions arising from the preparation of flood maps and an outline of strategic framework for their production in Slovakia. The key problems connected with preparation of flood maps are: estimation of the maximum annual discharge for different return periods, estimation of the water table, and extent of flooded territory corresponding to maximum annual discharges of different return periods. Stress is laid on different solutions to these problems depending on changes of spatial dimensions. The strategic framework of flood maps for Slovakia contains the set of basic theses concerning the selection of water streams, basic digital data sources, solution to the key problems, while certain differences in the nature of floods and number of gauging stations between the groups of great, medium and small streams are also highlighted. Differentiated approaches to the individual stream groups are outlined.

human geography, quality of life, objective and subjective dimensions, domains, indicators, human well-being

The field of quality of life studies and related dimensions, domains and indicators has widened in the past decades. Quality of life studies are regularly published in journals of several scientific disciplines presenting the results of basic and applied research. This paper explains the human geography approach of research into quality of life. Number of key conceptual and methodological issues is examined. Two basic dimensions (objective and subjective), several domains, indicators and some aspects of the conceptual model for quality of life research are presented. Finally, the usefulness of quality of life research in geography is assessed, and several conclusions for future research are suggested.

mean wages, wage discrepancies, decomposition, regional wage disparities, factors and characteristics, categories, Slovakia

The paper brings a survey of disparities in wages in Slovakia, their regional differentiation and development after 1989 with stress on the last two very successful years of the Slovak economy. The aim was to establish the level of wages in Slovakia and to confirm or deny the hypothesis about deepening wage disparities in the Slovakian regions. For the analysis of measured regional wage disparities one of non-standard econometric analyses was used, namely the method of decomposition. The measurements “in” and “between” components of wage disparities have facilitated identification of not only deeper causes and implications of regional wage disparities but also their effects and impact in regions under study. Relevant data published in “Regional Statistics of Labour Price” were used in this study. The Statistics, as an important source of information about labour price in the regions and factors that determine it, provides detailed information about wage level in individual regions of Slovakia. Among other things, the results point to two important facts: considerable regional wage differences and their continuous deepening.
