  • Forest engineering implication of storm-induced mass wasting in the Oregon Coast Range, USA
  • Oregon Coast Range and explores the potential of this technique, with special reference to storm damage assessment in commercial forestry areas.
  • surveys were used to characterize the nature of these events and relate the occurrence of mass wasting activity to the topography, geology, and land management activities of the region. This paper is based upon an aerial videography transect of the north

  • Située dans le North Coast Ranges (Californie), la forêt nationale de Mendocino s'échelonne de 300 à 2 400 m d'altitude et, présente une zonation du conifère au chapanal. Les données simulées de TM sont traitées par simple régression par bande et

  • The A. investigates the relative range elongation, with respect to maximum north-south distance and maximum east-west distance, of 269 North American tree species. These data provide evidence that species with smaller ranges tend to be elongated
  • north-south and species with larger ranges tend to be elongated east-west. This pattern is likely a result of species with small ranges being limited by local north-south-trending topography and species with large ranges being limited by major east-west
  • -oriented climatic zones, and is not merely an artifact of Rapoport's rule. Now, an explicit measure of range shape exists to compare to other biogeographical characteristics.

  • Fluvial and slope processes in the Fuirosos basin, Catalan Ranges, north east Iberian coast
  • Erosion rates in the southern Oregon Coast Range : evidence for an equilibrium between hillslope erosion and sediment yield
  • The purpose of this study is to calculate hillslope erosion rates in the unglaciated Oregon Coast Range, and to evaluate the relation of hillslope erosion to modern sediment yield. The hillslope erosion rates are calculated using dated colluvial
  • Evidence for regional stream aggradation in the central Oregon Coast Range during the Pleistocene-Holocene transition
  • The purpose of this paper is to describe the stratigraphy, distribution, and age of the fluvial sediments that underlie the youngest regionally extensive terrace along several rivers in the central Oregon Coast Range. The 14C age determinations

  • The axial ranges of eastern North Island have grown in different processes of development north and south of the Hawke's Bay area in the Quaternary. The northern axial ranges had emerged by the early Pleistocene, when parts of the southern axial
  • ranges were still submerged. Back-arc spreading extended from the Havre Trough to central North Island c.1.8 Ma. Eruption of ignimbrite began in central North Island c.1.1 Ma., and migrated to the Taupo Volcanic Zone c.0.6 Ma. Interrupted by a period
  • Stochastic processes of soil production and transport : erosion rates, topographic variation and cosmogenic nuclides in the Oregon Coast Range
  • Previous work in the Oregon Coast Range suggested that there may be a tendency locally toward equilibrium between hillslope erosion and sediment yield. Here results from a new methodology based on cosmogenic radionuclide accumulation in bedrock
  • minerals at the base of the soil column are reported. The AA. quantify how soil production varies with sol thickness in the southern Oregon Coast Range and explore further the issue of landscape equilibrium. Apparent soil production is determined

  • Le volume de la charge en suspension, constaté après la construction d'une route, a significativement augmenté sur deux bassins-versants de l'Oregon Coast Range. Les causes sont essentiellement l'érosion du terrain ameubli pour la construction
  • Az Eszak-magyarorszagi-hegyvidék alakrajzi jellemzése. (Morphographic description of the North Hungarian Mountain Range)
  • Author is concerned with the parameters of relative relief and valley density of the North Hungarian Mountain Range, which is of medium height and the most diverse macroregion in Hungary for its rocks and structure. Table 1 shows the morphographic
  • The geomorphology of the central Coastal Range, a north-south trending horst along the west coast of northern Calabria, is governed largely by major faults, fault scarps and the distribution of principal rock types, as well as by a variety of slope
  • Use of ergodic reasoning to reconstruct the historical range of variability and evolutionary trajectory of rivers
  • and Fryirs (2005) is presented as a means for depicting the range of behaviour and evolutionary variability of this river. These approaches can be readily applied in other systems. Implications for approaches to analysis of river evolution and management

  • Geomorphology and structure of the Bear River Range, north eastern Utah: a morphometric approach
  • The aim of this paper is to test the extent to which lithology and structure control the geomorphological evolution of a part of the Basin and Range Province by using the method of base-level surfaces.

  • Research initiated in 1909 by G. Leslie Adkin (1888–1964) suggested that the central Tararua Range on the North Island, New Zealand, was subjected to only limited alpine-style glaciation during the Late Pleistocene. This was based on the U-shaped
  • cross-profiles in the uppermost parts of several valleys, and cirque basins. Adkin’s work remained the only published glacial research undertaken on the North Island’s axial ranges until the latter part of the 20th century, but was not met with universal
  • Wind disturbance and development of a near-edge forest interior, Mary Peak, Oregon coast range
  • This study examines a noble fir (Abies procera) forest in the Oregon Coast Range to assess the role of wind disturbance in creating the structural characteristics of a developing forest interior. Specifically, the AA. explore how tree age and size
