  • 1997 has seen further evidence of the wide variety of issues and approaches impacting studies of the geomorphology of drylands. The dynamic nature of this field of geomorphology is also indicated by the number of special or theme sessions devoted
  • to this speciality at major meetings in 1997, including annual meetings of the Association of American Geographers and the Geological Society of America, as well as the 4th International Conference on Geomorphology in Bologna, Italy.

  • This paper describes the use of geomorphological mapping in the assessment of the natural hazards along a highway in eastern Taiwan, Taroko Gorge. Detailed records of the size and occurrence of rockfalls and landslides affecting the highway have
  • been obtained and analyzed and, by combining these data with the geomorphological and geological data, a hazard assessment map has been produced for the highway. This map may be used to improve the development of the highway, decreasing the danger

  • Decoherence, quantum theory and their implications for the philosophy of geomorphology
  • Concept ; England ; Geomorphology ; Philosophy of sciences ; Quantum mechanics ; United Kingdom
  • This paper draws lessons from quantum mechanics and the related concepts of decoherence and entanglement to explore the theoretical limitations of both of these existing approaches to geomorphology. It is suggested that empiricist and realist
  • . It concludes by suggesting that an idealist approach to geomorphology - one that recognizes the primacy of consciousness - can better appreciate the unpredictable and probabilistic nature of the world.

  • Special issue. Application of remote sensing and GIS in geomorphology
  • Computer analysis of integrated digital data sets can be exploited for geomorphological classification using automated methods developed in the remote sensing community. In this study, geomorphological classification in a moderate- to high-relief
  • area dominated by slope processes in southwest Yukon Territory, is performed with a combined set of geomorphometric and spectral variables in a linear discriminant analysis. An automated method was developed to find the boundaries of geomorphological
  • objects and to extract the objects as groups of aggregated pixels. The geomorphological objects selected are slope units.
