  • Regional analysis of erosion surfaces in southern Sweden
  • Aplanissement ; Géographie de l'Europe ; Socle ; Surface d'érosion ; Suède
  • The gross morphology of the Precambrian basement of southern Sweden is analysed. The area has a donned form and emerges from under a cover of Palaeozoic rocks in the north and east and Mesozoic rocks in the south and west. A map of erosion surfaces
  • has been constructed for the southern part of the area. Exhumed sub-Cambrian, sub-Jurassic and sub-Cretaceous inclined surfaces are cut by more horizontal surfaces at different levels.

  • Remote sensing of land surface parameters of relevance to climate studies
  • This article is devoted to summarizing the basic techniques which have been developed to evaluate surface temperature, albedo, moisture and vegetation cover and the physical and statistical models which have been formulated to remotely assess, from
  • these surface parameters, evapotranspiration, surface fluxes and surface energy balance.
  • Near-surface wind flow around desert shrubs
  • Wind profiles near the surface were measured at different locations around shrubs at six field sites. Estimates of the magnitude of surface shear stress around shrubs indicate that the presence of shrubs decreases shear stress on the surface
  • and that the degree of protection is partly related to the density of shrubs on the surface.

  • The A. argues that Yu. P. Seliverstov made a mistake when relating the Lower Cretaceous surface in Kazakhstan to the Gondvana surface in Africa : in fact it corresponds to the African surface which bears a thick lateritic crust. The latter is also
  • erroneously equated by Seliverstov with the Eocene surface in Kazakhstan which bears a thick lateric crust. The latter is also erroneously equated by Seliverstov with the Eocene surface in Kazakhstan which bears only siliceous crust of weathering. - (L'Ed.).

  • Smooth statitical surfaces are conventionally represented by isoline maps or block diagrams. Perceptual studies have suggested that these illustrations are difficult for map readers to interpret and that overall surface configuration is particularly
  • elusive on isoline maps. This paper presents an alternative method of illustrating continuous surface. It employs a digital plotter to create finely-spaced point symbols that vary in size according to interpolated z-values. After photographic reduction
  • , the maps has the appearance of a continuous change in gray tone corresponding to the surface it represents.
  • Wind erosion characteristics of Sahelian surface types
  • The aim of this study was to determine and compare relative wind erosion potentials of the most representative surface types over a transect comprising most parts of southwestern Niger. For this purpose, mobile wind tunnel experiments were run on 26
  • dominant surface types. The effects of surface disturbance were additionally determined for 13 of these surfaces. The results, namely measurements of wind fields and mass fluxes, can be classified according to specific surface characteristics. Three basic
  • surface groups with similar emission behaviour and aerodynamic characteristics were identified: (1) sand surfaces, (2) rough stone surfaces and (3) flat crusted surfaces. These results are comparable with field studies of natural erosion events and similar
