A rational explanation of cross-profile morphology for glacial valleys and of glacial valley development
The purpose of this paper is, first to present an explanation of the cross-profile morphology based on the physical process of glacier flow and second to interpret development of the glacial valley cross-profile.
A rational explanation of cross-profile morphology for glacial valleys and of glacial valley development : a further note
The AA. discovered a misinterpretation in their original paper entitled : a rational explanation of cross-profile morphology for glacial valleys and of glacial valley development in earth surface processes and landforms, vol. 13, No 8, p. 707-716
Late Wisconsin groundwater discharge environments of the southwestern Indian Springs Valley, southern Nevada
This report presents the results of a comparative study of the sedimentologic and faunal evidence from late Wisconsin sediments in the Indian Springs Valley and existing groundwater discharge environments of the Steptoe and Butte Valleys
Valley modification by sapping processes in southern Indiana
Valley form varies throughout the study area. The region is too small to have any climatic variances, nor is the vegetation significantly different. These valley forms are primarily a function of lithologic discontinuities, structure, and multiple
Morphotectonics of the Baikal rift valley, Eastern Siberia, USSR
The Baikal rift valley, the central segment of the Baikal rift zone located in southern East Siberia, consists of two large depressions separated by an interdepressional uplift. The interdepressional uplift consists of subsiding residual steps
and active tilted horsts. The large dimensions of the Baikal rift valley are evidently due to its being confined to the faults striking NE-SW.
The article shows some aspects of the temperature climate in a valley and its surroundings at Maze on Finnmarksvidda, where three meteorological observation stations have been in operation since the autumn of 1981. The stations are situated
at the bottom, on the side and at the top of the valley, as a part of a local climate project in connection with the building of the Alta hydroelectric power plant with its dam downstream Maze.
Limestone valley systems in north central Jamaica exhibit varied hydrologic regimes which reflect differences in karstic and non-karstic water supply. Valley patterns are influenced considerably by geographical structure, whilst fluvial erosion
Comparative geochemistry of volcanics from rift valleys, transform faults and aseismic ridges
It is suggested that transform faults have, by faulting, exposed more fractioned types of basaltic rocks (may be as intrusives) than the rift valley volcanics. While aseismic ridges have undergone a greater degree of differentiation than both
The influence of debris flows on channels and valley floors in the Oregon Coast Range, U.S.A.
The A. presents a field study of the erosional and depositional characteristics of debris flows and their influence on alluvial channels and valley floors.
Valley formation initiated by ice wedge polygonal nets in terrace surfaces
Based on observations of present day valley formation through thermokarst processes in river terraces of Spitsbergen, some mainly fossil valleys (gullies) in marine terraces of the Varanger peninsula are analysed. A more developed, dry valley
Submarine valleys can be subdivided into several types which differ considerably in genesis and morphology| besides submerged fluvial and glacial valleys (inherited relict features), several types of submarine valleys seem to be accounted
for by turbidity currents, i.e. submarine canyons, submarine gullies, abyssal valleys of continental rise and ocean floor. Rift valleys are formed by tectonics only| tectonic fractures contribute considerably into formation of submarine canyons and transversal
gorges crossing mid-oceanic ridges. Bottom abyssal currents are not sufficiently studied, but it is beyond any doubt that they participate in the formation of submarine valleys in deep ocean zones, in particular in inter-depression passes. It seems
that valleys due to turbidity currents were greatly influenced by Pleistocene glaciations. Ice edge was often situated close to shelf edge and debris melted from the ice created large turbidity currents which eroded not only continental slope but abyssal zones

Morphological development of dunes in a subarctic environment, central Kobuk Valley, northwestern Alaska
The morphology of the dune fields is described by airphoto interpretation supplemented by field observations. Dune forms indicate that both present-day and former wind directions are parallel to the valley axis. Therefore it is proposed that wind
Observations of sorted patterned ground features, High Valley/Tangle Lakes region, Central Alaska, U.S.A. in Periglacial processes and landforms.
These features have been studied since 1981, and since 1982 sorted circles at six patterned ground sites in High Valley have been monitored to determine their degree of activity.
The geoecology of subalpine heaths in the Abisko Valley, northern Sweden. A study of periglacial conditions.
The purpose of this study is to study the processes, both active and inactive, which influence the formation, structure and distribution of subalpine heaths in the Abisko Valley and to compare their ecotope with the adjacent birch forest.
Meteorologische Probleme der Luftverunreinigung in Talbecken. (Meteorological problems of air pollution in valleys)
In valleys and basins of an uneven relief the general winds are considerably changed, if they reach the bottom at all. Specific conditions are found, however, if the basins are filled with cold air lakes. In such a basin-atmosphere, weather
Fluvial deposits of the middle Kuiseb valley, Namibia
A variety of fluvial deposits of various ages occur in the middle Kuiseb valley in arid Namibia. The characteristics, lithology, spatial and altitudinal relationships and possible chronology of these fluvial deposits are considered. Conclusions
Riftward younging of volcanic units in the Addis Ababa region, Ethiopian rift valley
A general riftward younging of surficial volcanic units is a feature of the Addis Ababa sector of the Ethiopian rift valley. The narrowing of the volcanic zone with time in due to crustal necking and topographical control.
