Here the AA. report on a reconnaissance survey of the 137Cs content of recent alluvial sediments in the Huntervalley, N.S.W., Australia. They attribute the absence of 137Cs from recent sediments, in part, to the nature and magnitude
Automated recognition of valley heads from digital elevation models
An automated technique for recognizing valley heads from digital elevation models is presented. The technique has been developed for valley head recognition because valley heads are known locations of geomorphological activity and because areal
features have been largely ignored in the automated landform recognition literature. The problem of valley head recognition is divided into valley head location and valley head delineation, and the technique is developed using a DEM representing a simple
The evolution of the Vistula river valley between Cracow and Niepołomice in late Vistulian and Holocene times
Evolution of the Vistula river valley during the last 15 000 years, part IV
Alluvium ; Climatic variation ; Drainage network ; Fluvial processes ; Holocene ; Human impact ; Poland ; Quaternary ; Sedimentology ; Valley ; Valley floor evolution ; Wisła
This is a new synthesis of the evolution of the section of the Vistula river valley. There are changes in the channel patterns and parameters, sedimentological characteristics of the different alluvial deposits of different ages, the reflection
of both climatic fluctuation and human activity in the valley floor morphology and in alluvia. - (DG)
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 application of fuzzy classification to soil pH profiles in the Lockyer Valley, Queensland, Australia
This paper examines the application of fuzzy classification to the pH profiles of soils in the alluvial plain of the Lockyer Valley. Fuzzy classification usefully demonstrates relationships between profiles among the transect and is a potentially
Klimatologische und vegetationskundliche Höhengradienten im Death Valley National Monument
Gradients climatologiques et botaniques dans le Death Valley National Monument
Les montagnes bordant la dépression de la Death Valley sont un modèle idéal pour étudier les gradients verticaux, climatiques et écologiques, dans les zones arides, car cette région représente un désert extrême avec un potentiel botanique important
Stereoscopic remote sensing data between 1971 and 1986 for the Bagmati valley revealed no overall increase in erosion losses, although local shifts in eroded terrain were detected.―(DWG)
Nivation hollows and valleys in the fossil coast cliff Landborgen at Helsingborg, South Sweden
Most of the main nivation hollows and valleys are older than the last phase of the Weichselian glaciation as indicated by the fact that they contain till or morainic boulders from the north eastern ice, the main ice stream in Skåne during the last
glaciation. Hydro-thermal water has made hollows and rill water small valleys in the cliff where the nivation processes begun. The nivation processes were caused by drifting snow from the east during the Weichselian.
Ambootia Landslide Valley in the Darjeeling (Himalaya) active science 1968

The paper presents geomorphological, soil and hydrological research on the landslide valley located in Ambootia T.E., continuously active since the extreme rainfall in October 1968 exceeding 890 mm. The landslide covers an area of 56.5 ha, its
lenght exceeds 1 300 m. The present landslide starts at 1 065 m a.s.l. and ends at the apex of proluvial fan at 488 m a.s.l. In 1968 an old V-shaped side valley has been overdeepen about 30-60 m by big debris flow and rockfall. Further transformation
High-technology agglomeration and the labor market : the case of Silicon Valley
These relations are examined, drawing upon the results of a mailed questionnaire survey of firms in the semiconductor industry. The analysis is focused upon the cluster of specialized firms in Silicon Valley, to determine the contribution of local
Slow soil movement in Tarfala valley, Kebnekaise Mountains, Swedish Lapland
Between 1982-1990, on the slopes of Tarfala valley above timberline, at an altitude 1140-1220 m a.s.l., soil movement was measured by means of wooden pegs (columns) inserted in the soil. Three types of soil movement were distinguished : two were
