regional frequency analysis, regional type, hydrological heterogeneity, L-moments, regional distribution function, T-return period discharge

The paper deals with the issue of T-year maximum discharge for basins with a relatively short gauging or ungauged basins by the method of regional frequency – index-flood analysis. Identification of physical regional types is carried out by the method of hierarchic and non-hierarchic cluster analysis and application of logical principles. Setting of an optimum number of physical regional types for the purpose of regional frequency analysis leans on the test of heterogeneity inter se regarding the regional coefficient values of L-variation by means of pair comparison. Division of Slovakia’s territory into four physical regional types identified by application of logical principles seems to be the optimal solution. Regional distribution functions were established by the method of L-moment ratio diagram. Values of maximum annual Q100 discharges estimated by the index flood method for the set of 34 basins within the selected regional type are 2-3 times lower than estimates obtained by application of the empirical regional formula

hypercycle, geomorphological process, geomorphological form, phase shift, fluctuation, non-simultaneousness

Isomorphy exists in the response of small valleys to extreme precipitation. The similarities are expressed by the notion hypercycle; partial cycles of the hypercycle and the phase shifts between them have been identified. The possibility of fluctuation of the hypercycle is suggested and the non-simultaneous procedure of hypercycle in small valleys is described. The methodological status of the hypercycle as a working hypothesis is determined.

human geography, Slovakia, research assessment, Institute of Geography of the Slovak Academy of Sciences, transformation of society

This paper is an attempt to assess the current state and future prospect of human geography at the Institute of Geography of the Slovak Academy of Sciences, especially focused on the period of transformation. The paper looks first at the objective and subjective assessment of the geographical environment in the transformation period through the analysis of human geographical contributions characterizing: population structure and development, migration, unemployment, poverty, social pathology, human development and quality of life, sustainable development issues, industry and transport, rural space and its changes, cities and their changes, regional development, perception, attitudes, evaluations, expectations, images related to basic life needs, place, environment, sustainable development, regional development, inter-ethnic and inter-confessional relations, etc. In the next part, the paper considers the main successes and problems of human geography at the Institute of Geography. Finally, the paper deals with the future prospects of human geographical research and notes considering some of expected new developments.

conventions in cartography, orthogonal principle, orientation to the North, graphic scale of map

Production of maps can be traced back to the Upper Palaeolithic. Since then a great amount of knowledge has been gathered in the field of means of map expression. Many of them are considered conventional. The paper deals with the development of well-known conventions applied to maps: the orthogonal principle, orientation aspects and graphic scale of map.

vegetation mapping, insolation, cluster analysis, Mt. Devínska Kobyla

The existence of a close relationship between the vegetation and local climate has been known for a long time and is one of the most significant relationships in the landscape. Insolation affects all kinds of other topoclimatic characteristics (air temperature, soil temperature, relative air humidity, etc.), which are essential for the development of vegetation associations. In this paper we focused on spatial differentiation of the vegetation, we have made a digital terrain model and evaluated insolation. We studied the tightness of relationship between differentiation of the vegetation cover and insolation. The study area (1,8×1,2 km) is situated in the northerly sections in the National Nature Reserve Devínska Kobyla. It forms a belt-shaped part of the Devínska Kobyla subsection, the most southern section of the Malé Karpaty (Mts.), called the Devínske Karpaty (Mts.). The area is located between the Danube, and Morava Rivers, where the Carpathian Mountains meet with the Pannonian Basin. Its unique geographical position resulted in extraordinary physical-geographical conditions.
