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
in geomorphology are given. The first examples involves glacier surging and the second involves landslide susceptibility. The examples demonstrate the relevance of GLM to many common problems in geomorphology.
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.

This paper will examine the characteristics and distribution of rock glaciers in the Karakoram Mountains and northern India to highlight importance as geomorphological agents and to assess geomorphological significance.
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.
Palaeofluvial geomorphology in southern Africa : a review
This article presents an overview of palaeofluvial geomorphology research in southern Africa, including South Africa, Zimbabwe, Namibia, Lesotho, Swaziland and Botswana. It is suggested that southern Africa fluvial systems have shown large-scale
The concept of a geomorphological signature is developed for classifying and mapping slope units with an automated procedure for analysing digital elevation and remote sensing data. Slope units are extracted from a digital elevation model (DEM
The basic concept of the elaboration was a geomorphological analysis to be carried out jointly with that of its framing river valleys (Hernád, Bódva) constituting the relief boundary. The general evolution of the Hernád Valley : the article provides
an analysis of the present-day geomorphological and economic role of the high bluffs suggesting a substantial part played by slumps in their ongoing formation, which is a specific feature in the area of the North Hungarian Mountains. A similar analysis
This paper demonstrates that a combined study, based on geomorphological, stratigraphical and tectonic analysis, allows precise understanding of the structure and evolution of an active fold. The aims of the study are to document : 1) the structures
that accommodate lateral propagation on an active fold; 2) the orientation of the principal stress-axis inferred from fault population analysis in the pretectonic Toukoshan Formation and syntectonic deposits; and 3) the tectonic geomorphology of the Pakuashan
