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

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.
Modelling some influences of soil erosion, landslides and valley gradient on drainage density and hollow development in Geomorphological models. Theoretical and empirical aspects.
This paper raises a number of questions about the position of stream and valley heads. Two processes have been discussed as possible candidates for valley enlargement (wash, landslide).
