  • Economic and population potential fields in Central Europe
  • In this study I make an attempt to map the economic and population forcefield of Central Europe with the application of the potential model. Accordingly I analyse the effect of the western part of the area on East-central Europe in a core-periphery
  • relation : how does it influence its position in the potential fields. Beside I try to search local centres in East-Central Europe (both in the economic and population forcefield), which can counterbalance the effect of the western parts. I pay emphasized

  • Structure of flow over alluvial bedforms : an experiment on linking field and laboratory methods
  • This paper presents results of a field study designed to examine the structure of flow over mobile and fixed bedforms in a natural stream and to compare the results with findings of previous laboratory studies within the framework of double time

  • Soil detachment and transport on field- and laboratory-scale interrill areas : erosion processes and the size-selectivity of eroded sediment
  • This study compares the dynamics of interrill soil erosion processes and particle-size selectivity at laboratory and field scales in the semi-arid environment of Senegal. Specific objectives were : to determine the quantity and the size

  • A field experiment on streambed stabilization by gravel structures
  • The AA. report an experiment to study particle restraint imposed by bed surface aggregate structures in a small headwater stream, East Creek, east of Vancouver, British Columbia. They demonstrate both the effect of structure development on particle
  • transport and the remarkable sensitivity of bedload to changes in sediment supply near threshold conditions. The series of floods during the study period in East Creek illustrates the dynamic nature of reach-averaged clast restraint. The development of bed

  • In Slovenia, soil research of a given landscape is often neglected in physical geography studies. Despite the fact of an equivalent position of soil geography within the science system of Slovene geography. Reasons can be found in time consuming
  • field research, expensive laboratory analysis and soil data and also the lack of its own methodology. The drawbacks could be partially replaced by different approaches of research and especially to establish links with other physical elements
  • of the environment. The use of easily accessible digital and cartographic data, basic field techniques, in combination with simple GIS tools and quantitative methods overcomes many of the financial or time contraints. - (IKR)

  • This study uses two-dimensional macro-fabric analysis as a recorder of the dominant mode of mass-wasting on a slope. Clast trend and plunge data were collected from 68 sites at Eagle Summit, Alaska, and examined in two separate dimensions
  • : the plane of the slope to represent the sress-field driven by gravity; and in a vertical plane trending down the slope to represent the stress-field created by frost heaving pressures. The results presented here suggest that slope angle plays an important

  • A case study in a small catchment on the Loess Plateau indicated that sediment concentrations were considerable, and literature data suggested that for such sediment concentrations, corrections for settling velocity, fluid density and viscosity

  • This study reports on a set of wind tunnel experiments designed to examine the dependency of the mass transport rate on water contents that are distributed through space and time. The goal is to simulate and monitor surface conditions that provide
  • a closer representation of nature than achieved in previous simulations by the AA. Finally, the implications for modelling aeolian transport on beaches are explored briefly in the context of a field site assessment during the initial calibration

  • The aim of this paper is to present the findings of a field-based study on the rates of gully erosion in the Siwalik Hills. Three large and active gullies were selected. Aerial photographs taken in 1964, 1978 and 1992 were ortho-rectified and use
  • to study the dynamics of gully heads. The same gullies were also monitored manually. The findings are useful for planning and executing appropriate control measures and constructing a sediment hazard map at the catchment scale.
