  • Influence of topography on some vegetation cover properties
  • Human impact ; Kazakhstan ; Numerical model ; Phytocenosis ; Plant cover ; Soil properties ; Topography ; Vegetation ; Vegetation dynamics ; Watershed
  • The AA. study the influence of 9 local, non-local and combined quantitative topographic characteristics on vegetation cover, altitude and density in 4 areas of the Rudny Altai. Differentiation of plant properties is shown to depend on relief

  • Agricultural practice ; Duricrust ; England ; Experimentation ; Geographical information system ; Micromorphology ; Photogrammetry ; Plant cover ; Rainfall simulation ; Soil ; Soil properties ; Splash ; United Kingdom ; West Sussex
  • The interactions between the spatial pattern of soil crust development and crop cover conditions are investigated through controlled laboratory experiments using rainfall simulation. The experimental responses are monitored by using terrestrial

  • Geomorphic and forest cover controls on monsoon flooding, central Nepal Himalaya
  • Deforestation ; Discharge ; Flood ; Geomorphometry ; Himalaya ; Hydraulic works ; Inundation ; Monsoon ; Nepal ; Plant canopy ; Regional planning ; Watershed
  • Deforestation is often blamed as the principal cause of flooding during the monsoon period. However, bank-fall discharge at 22 stream crossings provide data to show that 82 percent of its veriation had nothing to do with forest cover. - (DWG)

  • Correlations between DEM-derived topographic indices and remotely-sensed vegetation cover in rangelands
  • Arid area ; Australia ; LANDSAT ; MSS ; Northern Territory ; Pastureland ; Piedmont ; Plant cover ; Remote sensing ; Rill wash ; Soil erosion ; Soil moisture ; Topography ; Watershed
  • This paper examines the effect of topography on vegetation cover on the mountain ranges, alluvial fans and footslopes of drainage basins in arid central Australia. The AA. use the topographic indices commonly employed in distributed hydrologic
  • and erosion models as indicators of moisture redistribution and soil loss or accumulation in the landscape. The spatial patterns shown by these indices are compared with the observed distribution of vegetation cover obtained from satellite imagery.

  • Australia ; LANDSAT ; New South Wales ; Plant cover ; Remote sensing ; Semi-arid area ; Thematic Mapper ; Vegetation ; Vegetation index
  • In this study, a semi-arid shrubland in western New South Wales was used to test a number of vegetation indices developed from Landsat Thematic Mapper sensor data. Vegetation cover varied from a mean of 22% in mid-summer to a mean of 78% in mid
  • -winter. There was no significant relationship between the Normalised Difference Vegetation Index (NDVI) and summer vegetation cover, though there was a significant relationship with total vegetation cover in winter. The Landsat Thematic Mapper vegetation

  • Data base ; LANDSAT ; New Zealand ; North Island ; Plant cover ; Remote sensing ; SPOT ; Thematic Mapper ; Thematic mapping ; Vegetation ; Vegetation dynamics
  • This paper reviews four methods of examining current land cover features using remotely sensed data, and describes the application of the preferred method to a study area of about 500 km2, on the North Island west coast where 36 NZLRI (New Zealand

  • Aeolian features ; Aeolian transport ; Arid area ; Experimentation ; Plant cover ; Roughness ; Vegetation ; Wind erosion
  • This paper is concerned with the development of predictive relations for application to the natural or spontaneous vegetation cover of arid and semiarid lands. Wind-tunnel experiments using arrays of model roughness elements to simulate vegetation
  • were conducted to determine the quantitative influence of vegetation structural attributes on saltation threshold. To this end, the influence on saltation threshold of lateral cover (also known as roughness density), element aspect ratio AR (= height

  • Geochemistry ; Isotope analysis ; Model ; Niger ; Numerical model ; Plant cover ; Semi-arid area ; Slope gradient ; Soil erosion ; Spatial variation ; Topography ; Tracer ; Wind erosion
  • This paper provides a semi-quantitative assessment of net soil flux, using 137Cs, and elucidates these patterns using topographic attributes and vegetation cover in a study area in southwest Niger.
