  • The origin of certain wide valleys in the Canary Islands
  • Canary Islands ; Geomorphology ; Inverted relief ; Lava flow ; Model ; Valley ; Volcanism
  • The present work addresses a long-term controversy concerning the origin of Orotava Valley, one of the most peculiar valleys in the Island of Tenerife. Analysis of the key features of Orotava Valley leads to formulation of an hypothesis which could
  • be applicable to numerous volcanic areas. Such valleys are developed as volcanic valleys undergo lateral expansion due to repeated alternations of processes: initial erosion of the gorges by streams, the burial of the gorges by lava flows, and the inversion
  • of the relief by erosion at the base of valley walls.

  • Duricrust development and valley evolution: process-landform links in the Kalahari
  • Botswana ; Duricrust ; Fluvial erosion ; Groundwater ; Namibia ; Palaeo-environment ; Stratigraphy ; Valley ; Weathering
  • This paper aims to explore the process-landform relationships and potential genetic links between duricrust formation and Kalahari valley development, and hence assess the possible influence and implications of groundwater weathering and erosion
  • upon duricrusts. This is achieved by consideration of relationships between valleys and duricrusts at a variety of scales (ranging between microscale to valley scale) from three mekgacha systems within the Kalahari: the Rooibrak and Letlhakeng valleys
  • in Botswana and the Auob Valley in Namibia.

  • Valley asymmetry on south-eastern Alexander Island, Antarctica, and valley forms in the High Drakensberg, Southern Africa
  • Africa ; Antarctica ; Cold area ; Earth surface processes ; High mountain ; Model ; Pleistocene ; Quaternary ; Slope ; Southern Africa ; Valley
  • Field data from Alexander Island, Antarctica, are used to develop a model for the formation of asymmetrical valley-side slopes. The application of the model to high altitude valley slopes formed in the Pleistocene in the Drakensberg is considered

  • Fossil valleys of the Mostecká pánev (Basin)
  • Czech Republic ; Fluvial dynamics ; Fluvial processes ; Fluvial terrace ; Meander ; River bed ; Valley ; Valley floor evolution
  • Valley stretches abandoned by watercourses at Quaternary, represent district landforms of the fluvial erosion-accumulation relief in the northern part of the Bohemian Upland. Four abandoned valleys and numerous Ohře River meanders were discussed

  • Picturing the Central Valley
  • California ; Central Valley ; Espace rural ; Esthétique du paysage ; Etats-Unis ; Paysage culturel ; Paysage rural ; Région agricole
  • The Central Valley, California's richest agricultural region, does not correspond to romantic pastoral ideals perpetuated by American high culture. The A. describes its special character as photographers have seen it and finds in its utilitarian

  • Fluvial chronology and valley floor evolution of the upper Bowmont valley, Borders Region, Scotland
  • This paper presents data from a number of sources (aerial photographic interpretation, field mapping, cartographic, radiocarbon and palynological dating), in order to establish limits to the ages of valley floor terraces on one such upland stream

  • that they were eroded by groundwater seeps fed by proglacial lakes dammed by the outwash plains and associated moraines. Valley erosion terminated after the lakes were drained and the water table dropped.

  • Concentrated economic power and Silicon Valley

  • There are three perspectives to characterize the Silicon Valley. The Valley's success can be seen as a story about supremely independent entrepreneurs. It can also be seen as a full-fledged industrial district made up of a dense thicket of mostly
  • small and medium-sized flexible specialists that cooperate and compete with one another. The third perspective (dominant tendency) is that the Valley is a world headquarters of global networks of big firms and their subcontractors, subject

  • Aminostratigraphic correlation and geochronology of two Quaternary loess localities, central Mississippi Valley
  • Amino acid epimeric (aILe/ILe) values from terrestrial molluscs are used to define and correlate three aminozones in loess sequences exposed across the central Mississippi Valley, in Arkansas and Tennessee. The AA. comment on age implications
  • of these data to existing Quaternary stratigraphic frameworks in the northern and southern Mississippi Valley.

  • that typically occurs on uplands, terraces, and valley margins in the region. Past climatic conditions, which favored erosion of loess, as well as a temporally erratic spatial extent of former continental ice sheets in North America, which provided the dust
  • supply, probably account for the low number of loess units along the Mississippi Valley.

  • Moraine and valley wall collapse due to rapid deglaciation in Mount Cook National Park, New Zealand
  • Since the 1880s, the ice mass on the Tasman Glacier on South Island has been shrinking. Beginning in the 1960s, lateral moraines and valley walls began to undergo slope failure of which the A. identifies four distinct types. Suggests a seasonal

  • Seepage erosion and its implication to the formation of amphitheatre valley heads: a case study at Obara, Japan
  • Seepage erosion was investigated in an amphitheatre with a semicircular valley head, steep slopes, and a flat bottom developed in granodiorite hills at Obara, Aichi prefecture, Japan. The sediment yield of seepage erosion from pipe oulets

  • Subsurface hydrology of layered colluvium mantles in unchanneled valleys, South-Eastern Brazil
  • The effects of subsurface hydrology on the evolution of erosive processes inside layered colluvium mantles in unchannelled valleys are investigated. Tensiometer nests were installed in different morphological conditions with their specific depths
