  • Footpath morphology and terrain sensitivity on high plateaux : the Mamore Mountains, Western Highlands of Scotland
  • Variations in the morphology of a high-level footpath are characterized using a new approach that relates footpath morphology to 6 terrain units defined jointly by 2 contrasting plant communities. All 6 terrain units are characterized by distinct
  • footpath morphologies. The most critical factor affecting footpath morphology is the shear strength of the vegetation mat and underlying root zone. Pathway depths are limited by increasing shear and compressive strength with depth. Implications

  • The article deals with a glacial morphological study in the area and discusses about the results. First the authors describes the present glacial morphological knowledge and than gives the authors an overview about the methods. At last the authors
  • evaluate the results and classify the results of the glacial morphological study. - (IfL)

  • The effectiveness of airborne LiDAR data in the recognition of channel-bed morphology
  • , located in the Dolomites (Eastern Italian Alps). The results suggested a good capability of LiDAR data in the recognition of river morphology giving the potential to distinguish the riffle-pool and step-pool reaches.

  • Morphological analysis of the Sudd region using land survey and remote sensing data
  • An analysis of the vast wetland of the Sudd swamps in southern Sudan was designed to assess and describe interdependencies between morphology and hydrology. Findings based on field survey and remote sensing data include an assessment of the effect
  • of ground slopes and morphological features on spill and flooding of the seasonally flooded grasslands. Through bathymetric surveys and analysis of Landsat images, depth profiles and cross-sectional depth and flow distributions were established. Data from

  • Wood storage in three mountain streams of the Southern Andes and its hydro-morphological effects
  • This study analyses large wood (LW) storage and the associated effects on channel morphology and flow hydraulics in three third-order mountain basins covered in old-growth Nothofagus forests, ranging from the temperate warm Chilean Andean Cordillera
  • to the sub-Antarctic Tierra del Fuego (Argentina). Amount, characteristics and dimensions of large wood were recorded, as well as their effects on stream morphology, hydraulics and sediment storage. Results show that major differences in LW abundance exist

  • Meteorological controls on sand transport and dune morphology in a polar-desert : Victoria Valley, Antarctica
  • Meteorological controls on sand transport and changes in dune morphology were monitored for 11 days in November-December 2004 on a barchan dune in the Victoria Valley, McMurdo Dry Valleys. Sand transport in this environment was found
  • southwesterly winds were found to promote aeolian processes by dislodging surface sediments, with dune morphology responding rapidly. As a result, change in the morphology of the dunes of the Victoria Valley may provide an early indication of change in regional

  • A morphological approach to understanding preferential flow using image analysis with dye tracers and X-ray computed tomography
  • This paper describes a multi-scale approach to analyse transport mechanisms using visualisation techniques. Chloride and Brilliant Blue tracers were applied to undisturbed soil cores to examine the physical and morphological properties associated

  • morphology and morphodynamics at 3 permafrost sites in the Tatra Mts. are discussed in the context of the presence of periglacial landforms, especially indicative forms of permafrost. No distinct morphological evidence as to the presence of permafrost

  • , and how the choice of a trend model affects the variogram of the residuals from that trend. Similarly, the AA. show how decomposing kriging predictions into their trend and residual components can yield useful information on channel morphology. Cross
  • is directly proportional to the spacing between surveyed cross-sections, even in a reconfigured channel with a relatively simple morphology; sophisticated methods of spatial prediction are no substitute for field data.

  • Vegetation plays an important role in shaping the morphology of aeolian dune landscapes in coastal and semi-arid environments, where ecogeomorphic interactions are complex and not well quantified. The AA. present a Discrete ECogeomorphic Aeolian
  • Landscape model (DECAL) capable of simulating realistic looking vegetated dune forms, permitting exploration of relationships between ecological and morphological processes at different temporal and spatial scales. This simple vegetated dune model

  • frequently exceeded 1 m. The relative importance of swash, surf and shoaling processes in determining morphological change was examined using detailed field observations and a numerical model. The results strongly suggest that changes in the intertidal
  • morphology are accomplished by surf zone processes rather than by shoaling wave or swash processes. It was found, however, that swash action may induce a significant amount of local morphological change when the high tide mark is located on the upper bar

  • spatial and temporal behaviour. Results show that while the overall hillslope morphology was captured by the laser scanner, with the morphology of the rills being broadly captured, the characteristics of the rills were not well defined. These results
  • demonstrate that an even greater density of points is needed to capture sufficient rill morphology. Nevertheless, SIBERIA simulations of the hillslope demonstrated that the model was able to capture rill behaviour in both space and time when correct model

  • Bed morphology and generation of step-pool channels
  • In this paper the results of the flume study are presented that focus on bed morphology and the generation of step-pool channels. In contrat to a number of other flume studies, the generation and configuration of steps and pools was studied
