  • Evolution of an Alpine over-deepened valley (Upper Enns Valley, Austria) within the context of geomorphic and tectonic expressions
  • Austria ; Conglomerate ; Drainage network ; Geomorphogenesis ; Glaciation ; Neotectonics ; Quaternary ; Sediment transport ; Styria ; Tectonics ; Valley ; Vertical movement
  • The topography of the Upper Enns Valley results from both tectonic and erosive processes. In this paper, the AA. pay special attention to the importance of glacial and fluvial carving and the features of the present-day morphology; they outline
  • briefly the sedimentary pattern of the Ramsau Conglomerate. Finally, they present a model combining valley formation in relation with tectonic forcing and glacially induced overdeepening.

  • Shaping the Little Vistula Valley allowed economic use to be made of it by the early Middle Ages. At first, this took the form of the constructing of many mill streams, but then the system of fish ponds characteristic of the Valley landscape
  • to this day was also put in place (in the 16th-17th centuries). Numerous floods regularly devastated the ponds, and the receding of floodwaters was followed by the rebuilding of ponds. This brought significant changes in the landscape of the valley.

  • A high-quality, large 3D seismic data volume collected in a highly channelized stratigraphic series found in the upper 500 ms of the Sunda Shelf in offshore Indonesia was used to map incised valley development on this shelf. Defined on a seismic
  • grid at 25-m spacing, 10 valley bases were then exported to ArcGIS, which was used to define each valley's thalweg. Valley-base elevation and several seismic attributes were then extracted along each thalweg. Resulting correlations and relationships

  • The 1975–2005 glacier changes in Aosta Valley (Italy) and the relations with climate evolution
  • Here 3 glacier surface area records (years 1975, 1999 and 2005) available for Aosta Valley (western Italian Alps) have been synthesized. The 1975 data have been collected by previous AA. who compiled the first Aosta Valley regional glacier database
  • to describe the recent evolution of a representative subset of Italian glaciers. Aosta Valley glaciers lost 27% of the initial area during 1975-2005. The area change rate accelerated recently (1999-2005). Furthermore, the AA. find increasing temperature

  • Alps (The) ; Geomorphogenesis ; Geomorphology ; Glacial erosion ; Limestone ; Physical geography ; Pleistocene ; Slovenia ; Tectonics ; Triglav Lakes Valley
  • The paper deals with the problem of glacial erosion in the carbonate rocks in parts of the Julian Alps. The paper is critical to tectonic interpretation of geomorphological evolution of the Triglav Lakes Valley which denies the role of glacial
  • erosion and of other morphogenetic agents during the Pleistocene. The glacial and non-glacial morphogenetic factors cannot be completely neglected and the geomorphological evolution of the valley differs with such exclusively tectonic explanation.

  • A Miocene Continental Basin associated with the back thrusting of the Eastern Sierras Pampeanas in the Santa Maria Valley, Northwestern Argentina
  • This study addresses the structures of the Miocene sequences in the Santa María Valley, on which there has previously been a lack of information. The Santa María Valley was formed by 2 superposed tectonic events. The first event, during a phase

  • Aux origines de l’aménagement régional : le schéma de la Valley Section de Patrick Geddes (1925)
  • graphique de la Valley Section (coupe de vallée). C'est, à la fois, une coupe longitudinale de vallée aménagée et une métaphore de la dimension géographique du progrès économique et social que Geddes veut promouvoir. Des géographes comme Gary Dunbar et
  • Claude Raffestin ont affirmé que l'idée de cette Valley Section s'inspire du modèle du «bassin fluvial» d'Élisée Reclus avec qui Geddes a entretenu une longue et amicale collaboration que l'on peut suivre à travers les textes de leurs archives.

  • Geomorphological and geotechnical causes of anthropogenically induced rock-mass falls in the Wachau-Danube Valley (Bohemian Massif, Lower Austria)
  • The Wachau-Danube Valley represents a transverse valley, intersecting the Variscian Bohemian Massif. The exceptional cultural position of the region generated an increasing demand for building materials. Over the centuries quarrying had a sizeable
