  • Soil geomorphology―Present dilemmas and future challenges
  • Geomorphology : the research frontier and beyond
  • Chronosequence ; Concept ; Geomorphology ; Model ; Slope ; Soil ; Soil erosion ; Soil properties ; Soil science
  • This paper outlines some of the challenges facing geomorphology and suggests ways in which these problems may be tackled by an approach that integrates pedology and geomorphology.

  • Geomorphology as science : the role of theory
  • Concept ; Geomorphology ; Sciences ; Theory
  • The most useful view of geomorphology as a science is one in which theory is seen as central, but fragile, and in which theory and observation are viewed symbiotically with theory providing the generative force and observation providing a vital
  • policing role. Much of the current debate in geomorphology centers around differences in characteristics of theory, type of scientific arguments, and metaphysical perspectives among investigators working at different temporal scales. Full recognition
  • and understanding of these differences are essential for developing a unified approach to the science of geomorphology.

  • Geomorphological assets evaluation
  • Geomorphology and geoecology. Applied geomorphology
  • Applied geomorphology ; Concept ; Environment ; Human impact ; Impact study ; Landscape ; Natural hazards
  • After a general introduction into the problems of the evaluation of geomorphological assets and man and- environment relationships, the AA. discuss the relationships between geomorphology and Environmental Impact Assessment. The concept
  • of geomorphological asset has an inherent social implication. The integral concept of the landscape permits to offer to the political component the basic elements needed for correct and efficient choices.

  • Environmental geomorphology in Hungary
  • Geomorphology and geoecology. Applied geomorphology
  • Agropedology ; Applied geomorphology ; Cartography;Mapping ; Environment ; Forestry ; Geo-ecology ; Hungary ; Land use ; Model ; Mountain ; Relief
  • During the last decades the assessment of topography for various practical purposes has brought about a new research trend, environmental geomorphology. Several methods for environmental geomorphological mapping are presented : 1) applied
  • engineering geomorphological (geotechnical) mapping; 2) relief assessment mapping for land use survey and land evaluation; 3) relief assessment mapping for the allocation of various facilities (for instance, small reservoirs, garbage or toxic waste disposal

  • Fluvial geomorphology : where do we go from here?
  • Geomorphology : the research frontier and beyond
  • Ecology ; Environment ; Fluvial processes ; Forecast;Prediction ; Geomorphology ; Hydraulic works ; Land use ; Model ; Research
  • After a brief history of fluvial geomorphology, the A. considers the linkages with ecology, engineering, recreation and landuse managers and environmental studies. He outlines the part of modelling and prediction.

  • Glacial geomorphology : modelling processes and landforms
  • Geomorphology : the research frontier and beyond
  • The first section of this paper provides a very brief overview of the main trends in Anglo-American glacial geomorphology from 1900 to the present. The A. then discusses more detail work on process modeling of glacial landform development, an area
  • which he considers to be one of the major research frontiers in glacial geomorphology. This provides a basis for exploring what research techniques and priorities in glacial geomorphology might be like in the twenty-first century.

  • Geomorphology and structure of the Bear River Range, north eastern Utah: a morphometric approach
  • Drainage network ; Fault ; Geomorphometry ; Structural geomorphology ; United States ; Utah ; Vertical movement
  • The aim of this paper is to test the extent to which lithology and structure control the geomorphological evolution of a part of the Basin and Range Province by using the method of base-level surfaces.

  • Major geological and geomorphological research studies in english speaking Cameroon since independence: a historical review
  • Cameroon ; Geomorphology ; Pyroclastic ; Regional geology ; Seismicity ; Tectonics ; Volcanism
  • This paper reviews the major geological and geomorphological studies done on West Cameroon commonly known as the English speaking Cameroon region since independence (1961).

  • Geomorphology : the research frontier and beyond
  • Concept ; Congress ; Geomorphology ; Research
  • Introduction aux actes du 24e colloque de géomorphologie de Binghamton, tenu le 25 août 1993, en parallèle avec le 3e congrès de l'Association Internationale des Géomorphologues, à Hamilton, Ontario, 23-28 août 1993.

  • Geomorphology and seismotectonic elements in the Giarre area, Sicily
  • Aerial photography ; Fault ; Geomorphology ; Italy ; Neotectonics ; Seismicity ; Sicilia ; Structural geomorphology ; Vertical movement
  • . The methods used in this work are based on three stages of research: 1), the collection, elaboration and interpretation of bibliographic data about neotectonics and history seismicity; 2), the interpretation of aerial photos to identify geomorphological

  • The geomorphological impacts of limestone quarrying
  • England ; Geomorphology ; Human impact ; Impact ; Karst ; Landscape ; Limestone ; Quarry ; United Kingdom ; Water resources ; World
  • This paper explains why limestone is such an important commodity, examines the technique by which it is excavated, the geomorphological impacts of those techniques, and describes how such impacts may be minimised. It is based largely on research
  • in Britain. Quarrying may also impact on karst water resources, particularly where excavation takes place beneath the water table, but these impacts tend to be site specific whilst te geomorphological impacts are more general.

  • Conventional, genetic geomorphological mapping supplemented with morphometric data allows the application of these maps for the study of changes in geoecological pattern and land use. The example of the test area, delimited in the traditional wine

  • The changing geomorphology of the humid tropics
  • Geomorphology : the research frontier and beyond
  • Flood ; Fluvial processes ; Geochemistry ; Geomorphology ; Global change ; Human impact ; Precipitation ; Slope dynamics ; Soil erosion ; Tropical rain forest ; Tropical zone ; Weather type
  • It is debatable whether tropical geomorphology is intrinsically different from the geomorphology of other places. This paper primarily examines the research themes of the last ten years or so, identifies the major trends, and attempts to predict
  • and sedimentation in the rainforest, denudation efficiency in the humid tropics, the Quaternary evolution and changes, and the applied side of tropical geomorphology.

  • Geomorphological stability of sites for the long-term containment of uranium mining wastes in the seasonally wet Tropics, Northern Australia
  • Geomorphology and geoecology. Applied geomorphology
  • Applied geomorphology ; Australia ; Environment ; Mine ; Northern Territory ; Quaternary ; Rehabilitation ; Soil erosion ; Tropical zone ; Uranium
  • This study assesses the future long term stability of the Ranger Uranium Mine area by examining the past (Quaternary) evolution of landforms in the vicinity of the mine. Five categories of geomorphological stability are recognised on the basis
  • of the type and intensity of past and present geomorphological (erosional/depositional) processes. The oldest land surfaces are judged to be the most stable and consequently the best suited as sites for rehabilitated structures, as they have survived Holocene

  • Climatic warming ; Coastal erosion ; Deforestation ; Environment ; Geomorphology ; Glacier ; Global change ; Greenhouse effect ; Human impact ; Permafrost ; Precipitation ; Remote sensing ; Rill wash;Runoff ; Sea level ; Vegetation
  • In the last two decades concern with global environmental change has brought the role of anthropogeomorphology into sharper focus. Global warming, if it occurs, will have important implications for many geomorphological processes and phenomena
  • as a result of the direct effects of warming, as a consequence of other related climatic changes (e.g. précipitation change) and as a result of climatically moderated changes in major geomorphologically significant variables (e.g. vegetation cover
