Geomorphic features as indicators of climatic fluctuations in a periglacial environment, Northern Sweden
Geomorphic responses to climatic fluctuations in the periglacial mountain environment of northern Sweden, especially Abisko mountains, are discussed. Due to the complexities involved in the interpretation of rapid mass movement deposits, only
Sensitivity of landscape evolution and geomorphic processes to direct and indirect human influence
in several study areas are analysed. Data obtained indicate that people are nowadays the main geomorphic agent. It is proposed that growing population, wealth and technology is the driving force behind a widespread global geomorphic change that affects
landscape sensitivity. The effect of geomorphic change is added to that of climate change and implies an acceletation of landscape evolution rates as well as an intensification of geomorphic hazards. It is suggested that measures to mitigate geomorphic
change should be taken in order to curb the observed trend towards increasing geomorphic disaster occurrence. - (NF)

There is a hypothetical karst passage system. The reconstructed geomorphological map shows the previously wide erosional valleys of medium depth and the erosional-derasional valleys indicating their geomorphological and hydrogeological role. - (DLO)
Soil characteristics related to weathering and pedogenesis across a geomorphic surface of uniform age in Michigan
The AA. examined 4 soils that span the range of the development on a relatively young, sandy, upland geomorphic surface in Michigan. The purpose was to examine the degree of variation in pedogenesis and weathering on this surface, as indicated by 4
typifying pedons. In so doing, they hope to assist those who develop and use chronofunctions by heightening their awareness of the potential variation in pedologic development and weathering across geomorphic surfaces.
Examining the effects of urbanization on streams using indicators of geomorphic stability
Previous geomorphic studies of urbanization primarily consist of case studies documenting changes in hydrologic response and channel morphology, but offer limited predictive capabilities. However, channel-stability assessment methods have been
morphology and morphodynamics at 3 permafrost sites in the Tatra Mts. are discussed in the context of the presence of periglacial landforms, especially indicative forms of permafrost. No distinct morphological evidence as to the presence of permafrost
Lunettes dunes in the northeast Cape, South Africa, as geomorphicindicators of palaeoenvironmental change
The purpose in investigating the Buffelsfontein pan/dune complex was to record a further component of the palaeoenvironmental chronology of the northeast Cape and to indicate its potential for further elucidation of the Quaternary climatic
Geodynamic and geomorphic evolution of the Permo-Triassic Appalachian Mountains in Appalachian geomorphology.
By coupling a model of the basin evolution, the AA. can determine not only the mass of the Appalachians but their shape as well. The technique indicates a central Andean topography with average relief on the order of 3.5-4.5 km and width of 250-300

Forest roads and geomorphic process interactions, Cascade Range, Oregon
, measured and analysed using geographic information systems and sediment budgets for the road network. The net effect of roads was an increase in basin-wide sediment production. Overall this study indicated that the nature of geomorphic processes influenced
A major flood in February 1996 triggered more than 100 geomorphic features affecting forest roads in a 181 km2 study area in the western Cascade Range, Oregon. Eight types of features, including mass movements and fluvial features, were mapped

by automation of data recording ; 3. indices of intensity of some processes for example, of washing out, surface runoff etc. driven from 20-30 years long series ; 4. focusing the attention on anthropogenic influence on the geomorphic processes
The purpose of this paper is to provide an overview of the present-day geomorphic studies carried out in the Polish part of the Carpathians, their trends and directions during the recent 15 years. A significant progress in the research is evident
Geomorphic evolution of Medziphema intermontane basin and Quaternary deformation in the schuppen belt, Nagaland, NE India
and calculation of geomorphicindices.
The Medziphema intermontane basin developed in the schuppen belt of Nagaland, Northeast India, has been studied to understand its tectonic and geomorphic evolution on the basis of field evidence and morphometric parameters. Major part of the basin
The AA. focus upon the Kusai Lake-Kunlun Pass segment of the fault to understand the geomorphic development of offset streams caused by repeated large seismic events, based on tectono-geomorphic analysis of high-resolution satellite remote sensing
images combined with field studies. The results indicate that systematic left-lateral stream offsets appear at various scales across the fault zone. The Kusai Lake-Kunlun Pass segment provides an opportunity to understand the relationship between
geomorphic features produced by individual large seismic events and long-term geomorphic development caused by repeated large seismic events along a major strike-slip fault.
Allison (1988, 1990) examined the intact strength properties of several types of carbonate rocks and considered that dynamic Young's modulus is a good indicator of rock material strength for geomorphic purposes, and cast doubts on the reliability.

Contrasting geomorphic impacts of pre- and post-Columbian land-use changes in Anglo America
This review paper evaluates assumptions of pristine landscapes and European disruption from a geomorphic perspective, i.e., with regard to fluvial erosion and sedimentation rates. Geoarcheologic and sedimentologic evidence indicates
that the potential for geomorphic change with land-use practices utilized by European settlers was potentially very effective in producing erosion and sedimentation in Anglo America (United States and Canada). A general lack of evidence of rapid sedimentation prior
to the time of European contact implies that pre-Columbian agriculture was not highly disruptive geomorphically. Examples from northern California and the southeastern Piedmont support this interpretation by documenting geomorphically stable conditions
