  • Field scattering as agricultural risk management : a case study from Cuyo-Cuyo, Department of Puno, Peru
  • Peasants in the eastern Andean escarpment often have plots spatially removed from each other. Although net yields are reduced 7% on average by the additional travel and transport required to tend dispersed fields, harvests from them buffer
  • 1993
  • Field evaluation of empirical equations in straight alluvial channels
  • Six experimentally derived formulae that predict the conditions for alternate bar formation and equilibrium bar dimensions are assessed using field data. The study site is an artificially straightened section of the Embarras River located 16 km
  • south of Champaign, Illinois. Data were collected on channel form, gradient, alternate bar dimensions, bar sediment size, and flow conditions over a two-year study period.

  • Adaptation ; Africa ; Behaviour ; Cultural studies ; Southern Africa ; Woman
  • Field studies in Malawi, Zambia, Zimbabwe, Swaziland and South Africa indicate that pregnant women in rural areas eat earth, much of which comes from termite mounds. The A. argues that this practice is environmentally adaptive. - (DWG)

  • A simple method to assess the susceptibility of soils to form surface seals under field conditions
  • The aim of this study was to develop a simple, inexpensive method to assess the susceptibility of soils to form surface seals under natural tillage and rainfall conditions during a vegetation period, and also, to enable the comparison of sealing
  • 1993
  • The geomorphology of a field tunnel system: a case study from Australia
  • 1993
  • A review of recent urban geographic studies in India
  • The paper reviews the changing nature of the growing specialized trends of urban geography in India since independence, with a particular emphasis to the 1980s and early 1990. Urban geography has emerged as a major academic sub-field in India
  • 1993
  • Kuwaiti National Assembly 1992. A study in electoral geography
  • This study is an interesting field for the reflection of a regional and national democratic approach in governing the state. The consultative council and the legislative council gave way to the fist formation of a state parliament in 1963
  • 1993
  • The field study reported here had two objectives: to describe the bed geometry at confluences of unequal depth channels and 2) to examine the relationships between bed morphology, surface sediments properties and flow dynamics as discharge varied
  • 1993
  • Recent Canadian research on permafrost is reviewed, concentrating on permafrost-climate relations, the processes of thermokarst, ice-wedge development, frost heave and soil convection, and ground ice studies. This field of geomorphology is often
  • of direct interest to engineers and managers of northern resource development. Much of the work on the potential consequences to permafrost of climate change is by modelling. The review concentrates on the use of field evidence in support of analytical

  • Slope instability in slope management and mining : a case study of the upper Sele Valley, southern Italy
  • This paper presents a study on the causes and effects of slope instability on landuse planning in the Upper Sele Valley, using aerospace remote sensing and field mapping techniques. Slope instability is manifested by the presence of numerous

  • Integrated management, as a process which extends across resource disciplines and sectors, has been difficult to achieve, because property institutions appear to be of foremost influence. The A. draws upon a field study in a Canadian Inuit society
  • 1993
  • The object of this research is the study of those morphological elements caused by neotectonic movements, that are located in a narrow area on the eastern flank of Mont Etna, a zone in which several earthquakes with very shallow foci have occurred
  • structures due to neotectonics; and 3), data verification with field survey.
  • 1993
  • The purpose of this paper is to evaluate the relative importance of surface-gravity waves on sandbar stability in Grand Canyon, in contrast to unidirectional currents that are the primary focus of most fluvial studies. A second objective
  • waves are part of the flow field.

  • to information and personal attributes that reflect different fields of attention are further examined with an expanded version of the model. The case study is Beer-Sheva.
  • 1993
  • Some contributions to the study of landforms and geomorphic processes
  • The aim of this paper is to present the results of field experiments and to evaluate the efficiency of the applied preventive measures against the background of measured sediment yield. Special attention will be payed to the efficiency
  • 1993
  • Some contributions to the study of landforms and geomorphic processes
  • Character and stratigraphic division of the overlaying strata of the Bavarian Forest are described. The differentiation of stratum boundaries carried out in the field is verified by means of a wide spectrum of laboratory analyses. Different

  • The geomorphological and sedimentological field studies as well as the mineralogical investigation of 80 silty-clayish samples from the terraces of the Wadis Firan and Esh Sheikh (southern central Sinai) lead to new conceptions about
  • 1993
  • Field studies conducted on a small, saline and deeply weathered hillslope (in the Murray River catchment, 17 km WNW of Narrogin), using hydrologic, geomorphic and chemical measurements, were used to quantify and describe the various processes
  • 1993
  • The results presented here highlight the importance of synthesising standard geomorphological site investigation techniques with quantifiable rock geotechnical parameters, in order to understand slope form and development. Field research has been
  • undertaken along the Napier Range of the Kimberley Region. The study uses the bounding cliffs of an ancient limestone reef complex, which displays marked variations in morphology from steep, vertical cliffs on the one hand, to smooth concavo-convex forms
  • 1993
  • This paper offers a broad-based view of recent work, and shows how geomorphological survey and analysis have contributed significantly to land use planning in a number of areas, but particularly in the fields of coastal zone management, urban
  • development, water resource exploitation and environmental conservation. Selected examples are used to illustrate specific approaches, techniques and results. The study concludes that demand for geomorphological expertise in land use planning is likely
