  • Thirty years of detailed geomorphological mapping
  • Geomorphological survey and mapping
  • Cartography;Mapping ; Concept ; Geomorphology ; Methodology ; Photointerpretation ; Remote sensing ; Topography
  • The method of geomorphological mapping was adopted in many European and non-European countries, especially over the 1956-1986 period. Yet, mapping methods, especially of compilation of detailed geomorphological maps, still need to be made uniform
  • . Such maps are intended to determine the development of geomorphology and, simultaneously, are of considerable value for rational economic planning purposes.

  • Orfordness : geomorphological conservation perspectives
  • Coastal environment ; Concept ; England ; Geomorphology ; Nature conservation ; United Kingdom
  • This paper reviews conflicts between coastal defence strategies and the scientific study of geomorphological processes at the coast, and presents the results of a survey of the scientific importance of geomorphological features within the site

  • Geomorphology of the Himalaya : a climato-tectonic framework
  • This paper describes the plate tectonics setting, geology, topography, precipitation, erosion processes, sediment yield, and geomorphology of the Himalaya, and, using a climato-tectonic framework, discusses the north-south variation in geomorphology
  • across the Himalaya. The paper concentrates on the Nepal Himalaya, where erosion rates, geomorphology, and geology are better known.

  • Quantificational reductionism as a risk in geography instanced by the 1 : 25 000 geomorphological map of the Federal Republic of Germany
  • Geomorphological survey and mapping
  • Cartography;Mapping ; Concept ; Ecology ; Geomorphology ; Germany ; Scale
  • Reduction is the underlying principle of the Geomorphological Map (GMM) legends. The risk inherent in reduction is that the disintegration of complex phenomena into their elements can be irreversible. The synthesis of the complex from a precise
  • knowledge of the individual elements is therefore precluded. The question arising from this is whether it is still expedient, for the object of geomorphological research, to pursue the degree of reduction proposed in the GMM legend.

  • Review and prospect of experimental studies on fluvial geomorphology in China
  • The purpose of this paper is to review the achievements in fluvial geomorphic experiments and to predict the tendency in their development. The laboratories and stations in geomorphology in China are briefly listed.

  • Sea-level rise and geomorphological mapping
  • Geomorphological survey and mapping
  • of the progress in geomorphological survey and mapping is presented with The Netherlands serving as an example. Finally some remarks are made on useful geomorphological data : survey and mapping can contribute in encountering the problems caused by sea-level rise
