  • Concept ; Geomorphology ; High mountain ; Mountain ; Terminology
  • A contribution to the discussion of the term « high mountains » and the differentiation of high-mountains landscape from other types. The existing misleading terminological shortage could be eliminated by substituting the adjective « high
  • » by « cold » (relative « cold mountains », « cold landscape ». - (MS)
  • Digital terrain models for high mountains in Proceedings of a Symposium on High Mountain Cartography.
  • The use of orthophotographs and orthophoto maps in high mountain cartography in Proceedings of a Symposium on High Mountain Cartography.
  • Vertical distance, releif energy and altitudinal limits as distinguishing features of high mountains
  • Altitude ; Classification ; High mountain ; Mountain ; Relief
  • Mountain constitute the Earth's third pole, because they hypsometrically repeat the climate zones as far as the Arctic within smallest space. For this reason, the vertical distance and relief energy are characteristic and distinguishing features
  • of any classification of mountains. But when taking such basic features into consideration, geomorphologists, glaciologists and geobotanists have to define mountain-typological threshold values in a new way. - (IfL)
  • The high mountain fluvial system. The Western Tatra perspective
  • Carrying capacity ; Fluvial processes ; High mountain ; Hydrodynamics ; Mid-latitude zone;Temperate zone ; Mountain ; Poland ; Tatra Mountains ; Water cycle;Water circulation
  • On the basis of the 12 years of field studies (1975-1987) regularities in the dynamics of high mountain fluvial system in an annual cycle have been determined. The results have been compared with the results obtained for other high mountain regions
  • The influence of micro-climate, snow cover, and soil moisture on ecosystem functioning in high mountains
  • Climatic change ; Ecosystem ; High mountain ; Microclimate ; Mountain ; Norway ; Snow ; Snow cover ; Soil moisture ; Temperature
  • The dynamics of water and energy fluxes in the high mountains of central Norway was studied along micro-spatial topographic gradients in different altitudes and regions of the Scandes. Landscape ecological processes like snow accumulation during
  • characterisation of high mountain ecosystems.
  • Geomorphological mapping of high mountain relief, Federal Republic of Germany in Proceedings of a Symposium on High Mountain Cartography.
  • Geomorphometry ; Geosystem ; High mountain ; Model ; Switzerland ; Valais
  • Discussion of methods and techniques for the quantitative description of landforms particular in high mountains and application of these methods to several digital elevation models of the Turtmanntal in Valais. The absence of adequate methods
  • for the parameterisation of complex landforms is particularly evident for high mountain landforms. Therefore this study wants to contribute methodologically and in application to the description of geomorphometric structure in high mountain environments. - (IFL)
  • Persistence and chenge in high mountain agricultural systems
  • Geoecology and sustainable development in middle mountains and high mountains
  • Agricultural practice ; Agriculture ; Alps (The) ; Altitudinal zonation ; Europe ; Farming system ; High mountain ; India ; Jammu and Kashmir ; Mountain ; Pastoral ; Rural community
  • Mountain land use is viewed as a function of ecology, culture and economy working in concert. This perspective is examined in the agriculture and pastoralism of Kashmir and Juansar-Bawar (India) and in the Alps of Europe. - (DWG)
  • Alpine timberline in the High Sudeties
  • Czech Republic ; Mountain ; Sudety ; Tree line
  • The alpine timberline is an essential boundary in mountain relief. In the High Sudets, there are three mountain ranges rising above alpine timberline : giant Mts with largest alpine area, Králický Sněžníl which is small summit phenomena and Hrubý
  • Jeseník with seven alpine areas of different extent. A natural and human origin of the alpine belt in the High Sudets is discussed. - (MS)
  • Across-scale temperature modelling using a simple approach for the characterization of high mountain ecosystem complexity

  • Rock slopes of the High Tatras mountains
  • Geomorphogenesis ; Glacial features ; Mountain ; National park ; Periglacial features ; Rock ; Slope ; Slovak Republic ; Structural geomorphology ; Tatra Mountains
  • Substantial part of the alpine relief of the High Tatra is composed of rock slopes. Geomorphological analysis shows that the development of high rock slopes on crystalline rocks is guided, in principal, by their morphostructural position
  • and by the glacial and cryogenic modellation in the Pleistocene. Postglacial and recent changes continue in mainly periglacial conditions. Detailed observation of rockfall events in the High Tatras National Park will allow long term prediction and also local

  • Linkages between energy, environment, and society in the High Atlas mountains of Morocco
  • Atlas ; Energy ; Energy consumption ; Environment ; Fertilizer ; Fuel ; Morocco ; Mountain ; Resource management ; Society-environment relationship ; Tribe
  • Annual flows of energy, matter, and money were collected for the Ait Mizane tribe in the Imlil region of the High Atlas. Social and environmental pressures increasingly impinge on the system. - (DWG)
  • A Szovjetunio magashegységi okorendszerei és védelmük. (High-mountain ecosystems in the Soviet Union and their protection)
  • Of high-mountain ecosystems the diversity of species, a remarkable ratio of endemics and the widespread distribution of relict species are characteristic. These ecosystems of the Soviet Union are highly susceptible to changes and it is difficult
  • Classification and quantification of ground-destruction phenomena in ecosystems of high mountain regions of the Western Carpathians
  • Author deals with a location of the ground destruction in the system of geomorphological processes and classifies the phenomena and forms in high mountain, areas. An extend of the destroyed soil mantles and action of different morphogenetic

  • Earth surface processes ; Frost action ; High mountain ; Mountain ; Residual landform ; South Africa
  • The dimensions and sorting characteristics of minature sortes stripes at High altitudes in the Drakensberg are examined. The reasons for this preservation of cold-region landforms are postulated. - (AJC)
