  • Czech Republic ; Geomorphological mapping ; Geomorphology ; Moravia ; Slope ; Slope dynamics
  • Altogether ninety-three localities of slope deformation were identified in the NE parts of the Vizovice Highland, during the detailed geomorphological mapping. Special attention was paid to the deep-seated slope deformations in the central

  • The nature and rates of fluvial and slope processes change over time and space as urbanized areas replace forested land in Singapore. Storm-based and time-based data, from undisturbed rainforests, heavily disturbed construction sites, urban grass
  • -covered slopes and an experimental plot, are collected to observe the impact of rainwater on the soil moisture conditions, surface microtopography, runoff generation, sediment movement, and ground lowering in the three different categories of land use.

  • Mapping of slope exposure in Environmental and dynamic geomorphology.
  • Methods to map exposure of slopes, directly important for agriculture and influencing geomorphic processes too, are described. Percentage distributions are given of the exposure classes for administrative units, to promote regional planning. (DLO).
  • Flared slopes, footslopes, and the retreat of overhanging slopes : examples of convergent landform development
  • Australia ; Cave ; Concept ; Erosion ; Geomorphogenesis ; Granite ; Piedmont ; Slope ; Slope dynamics ; Weathering ; Western Australia
  • Flared slopes are concave slopes thought by some to be created by subsurface weathering followed by stripping. The AA. believe that concave slopes may also be formed by subaerial weathering, and that the retreat of such slopes creates rectilinear
  • footslopes. Such rectilinear slopes have also been related to flared slopes. The same landforms have been used in the past to illustrate both modes of formation, as illustrated by various examples including Ayers Rock and Hyden Rock in Australia
  • . The combination of concave and rectilinear slopes may produce convergent landforms that can be formed by different processes.
  • The determination of suction-controlled slope stability in humid temperate environments
  • Hydrology ; Model ; Permeability ; Scotland ; Slope ; Slope dynamics ; Soil properties ; Temperate zone ; United Kingdom
  • In this paper two models are employed to assess whether hillslopes in humid temperate environments may be suction controlled. In 1988 a series of storms produced several shallow planar slope failures, in freely-draining, permeable soils on slopes
  • in the Glen Livet Estate, Scotland. The two models, when applied to these slope failures, indicate the possibility that slopes may fail under unsatured conditions, and that their stability is thus controlled by the minimum suction which may develop
  • Effects of slope angle on mass movement by tree uprooting
  • Forest ; Mass movement ; Michigan ; Regression analysis ; Sandy soil ; Slope ; Slope dynamics ; Slope gradient ; United States of America
  • An examination of 189 well-delineated mounds and pits in sandy soils of northern lower Michigan, all presumably formed by tree uprooting, was used to determine the effects of slope angle on morphology and volume, and to assess the potential
  • importance of uprooting to mass movement. Data indicate that mound and pit volumes increase with increasing slope angle, suggesting that on gentle slopes more of the disturbed soil wastes off the mound, back into the new pit.
  • Effect of grain diameter and packing condition on the avalanching depth on a slope composed of dry granular materials
  • Experimentation ; Grain size distribution ; Honshu ; Japan ; Mass movement ; Slope ; Slope dynamics
  • To examine the depth of avalanching taking place on a slope at a critical angle of repose, tilting tests were performed in the laboratory using slopes made of granular materials such as gravels and glass beads. The AA. conclude that the avalanche
  • depth on slopes made of granular materials is determined by the diameter of the slope materials and by their packing state.
  • Periglacial slope deposits and landforms in a Hungarian mountain of volcanic origin in Environmental and dynamic geomorphology.
  • The early Pleistocene development of an almost 2 km long slope is reconstructed in the Tokaj Mountains, NE-Hungary. The variety of periglacial forms and geomorphic processes are described for the four distinct segments of the slope. (DLO).
  • Effects of rainfall intensity and slope gradient on the dynamics of interrill erosion during soil surface sealing
  • Erodibility ; Infiltration ; Israel ; Model ; Permeability ; Precipitation ; Runoff ; Slope gradient ; Soil erosion ; Water erosion
  • 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
  • that slope and rainfall erosivity are accounted for only partly in these models. A sandy soil from the Coastal Plain in Israel was used in this study, discussion of the results.
  • Field experiments on high mountain slopes of the Tatra Mts.
  • The authors present method and techniques of measurement for stating present-day dynamics of talus slopes in the surroundings of the research station of the Institute of Geography, Polish Academy of Sciences on the Hala Gasienicowa
  • . For the experimental slope of Skrajna Turnia photographs were taken and cartographic interpretation was made. To the slope surface certain morphological, genetic and dynamic features were ascribed. Point of measurement of Quick and slow mass movement were established
  • . Those points are chacked 2-3 times a year and they are the base for considering on rate and way of contemporary transformation of slopes. (d'après l'A.).
  • Slope aspect, slope length and slope inclination controls of shallow soils vegetated by sclerophyllous heath - links to long-term landscape evolution
  • Australia ; Biogeography ; Heath ; Impact ; New South Wales ; Sandstone ; Slope ; Slope dynamics ; Slope gradient ; Soil erosion ; Vegetation
  • On upland Triassic sandstone slopes of the western Blue Mountains in Southeastern Australian highlands, nonswamp, sclerophyllous heath (shrub-dominated vegetation) on shallow soils is commonly found downslope and adjacent to sclerophyllous forest
  • on deeper soils. The AA. test the strength of the relationship between aspect and heath/shallow soil distribution, and consider other possible controls related to erosion thresholds and slope inclination. Shallow soils vegetated by heath are more strongly
  • controlled by topographic factors other than slope aspect and the influence of aspect on long-term landform evolution is overwhelmed by other processes as landscape dissection increases.
  • An expert system for predicting the probable failure of a mountain slope during heavy rainfall
  • Expert system ; Forecast;Prediction ; Japan ; Mass movement ; Mountain ; Precipitation ; Slope ; Slope dynamics
  • An expert system for consulting probable failure of a mountain slope is proposed. PROLOG, an artificial intelligence language was used. To examine whether the proposed system is appropriate, the AA. applied it to an area. The results show
  • that the dangerous goals are obtainable for failed slopes and the safety goals for non-failed ones. The results show also that topographical factors greatly influence the occurrence of surface failure on mountain slope.
  • Mechanism for the instability of slopes composed of granular materials
  • Avalanche ; Experimentation ; Geophysics ; Mass movement ; Model ; Shear stress ; Slope ; Slope dynamics
  • The mechanism of instability of slopes composed of granular materials was examined through a tilting-box experiment using an assembly of aluminium rods and direct shear tests. Avalanching of granular materials is triggered by rotation of rods
  • at the slope surface. The force inducing the rotation was caused by the weight of the particles transmitted through contact points. Therefore, the mechanism of avalanching of granular materials was not comparable to the shear mechanism that has been considered
  • to be responsible for the instability of slopes made of granular materials.

  • In a series of computer simulations the question is treated: what is the impact of spatial differences in infiltration on long-term slope development? The computations suggest that different slope profils can be created under ensystemic conditions
  • not pnly by process-specific charakteristics but also due to differences in infiltration. For example, a convex sllope profil is formed, if there is declining infiltration along slope length. Increasing infiltration downslope results in a concave slope
  • profile whereas constant infiltration yields a more or less rectilinear slope profile.
