  • Rock glacier dynamics in a marginal periglacial high mountain environment : flow, movement (1991-2000) and structure of the Argualas rock glacier, the Pyrenees
  • This paper presents the results of detailed studies on the dynamics of the Argualas rock glacier in the Pyrenees from 1991 to 2000. The aim is to provide a better understanding of the surface movement and dynamics of the tongue-shaped rock glacier

  • Allogenic and autogenic influences upon riparian vegetation dynamics
  • Bank erosion ; Channel geometry ; Habitat ; Rehabilitation ; Riparian vegetation ; Stream ; Vegetation ; Vegetation dynamics
  • Various aspects of both allogenic and autogenic processes in riparian vegetation dynamics are discussed here; in particular how plants may promote bank stability and sedimentation, and river island development. Riparian restoration often fails

  • Bibliography ; Forest ; Geographical information system ; Landscape ; Landscape ecology ; Model ; Simulation ; Spatial analysis ; Vegetation ; Vegetation dynamics ; Years 1990-99 ; Years 2000-2009
  • This review considers the development and application of landscape-level spatially explicit ecological models, with an emphasis on vegetation dynamics and disturbance, and the management applications of these models. Mechanistic and stochastic

  • Hydrology and dynamics of a polythermal (mostly cold) High Arctic glacier
  • Arctic Region ; Canada ; Cold area ; Ellesmere ; Glacial flow ; Glacier ; Glacier dynamics ; Meltwater ; Northwest Territories ; Nunavut ; Polar region ; Thermal regime
  • To improve the understanding of the interactions between hydrology and dynamics in mostly cold glaciers (in which water flow is limited by thermal regime), the AA. analyse short-term (every 2 days) variations in glacier flow in the ablation zone
  • the extent to which the observed short-term variations in dynamics may impact on long-term mass balance.

  • Exploring potential spatial-temporal links between fluvial geomorphology and nutrient-periphyton dynamics in streams using simulation models
  • Biogeochemistry ; Biomass ; Channel geometry ; Ecosystem ; Model ; Nutrient ; Population dynamics ; River bed ; Stream ; United States of America ; Wisconsin
  • Using a nutrient retention and periphyton growth model coupled to a dynamic geomorphic template, the AA. explore the potential role of channel shape, slope, and sediment texture on downstream nutrient retention, and attempt to determine if physical
  • changes alone can drive or influence changes in nutrient-periphyton dynamics. The overall model results suggest there is a strong potential control of both nutrient retention and periphyton biomass by channel morphology.

  • Effects of rainfall intensity and slope gradient on the dynamics of interrill erosion during soil surface sealing
  • The dynamics of interrill erosion during seal formation is studied under different simulated rainfall and slope conditions. Soil erodibility during seal formation is evaluated using 2 empirical multiplication-of-factors type models. It seems
