  • Fan and playa areas in southern California and adjacent parts of Nevada
  • In bolsons in the desert regions of southern California and adjacent parts of Nevada, the area underlain by alluvial fan gravels and playa sediments is generally ∼ 1-2 times the area being eroded to produce those sediments. In certain larger basins
  • in the vicinity of Death Valley, however, the depositional area is only about half the size of the erosional area. This reflects the more active tectonic environment in these bolsons.

  • Glacial history and periglacial landforms of the Zackenberg area, Northeast Greenland: preliminary results
  • The geomorphology of the Zackenberg area has been investigated with the purpose of establishing a geomorphological map of a 260 km2 area around the planned research station. Production of a large digital three-dimensional elevation model, based
  • on the use of a multi-model photogrammetric method, has been the basis for a GIS database and a topographical map (1:50,000), covering the investigation area. Both glacial and periglacial landforms have been maped and a preliminary Late Weichselian glacial
  • history of the Zackenberg area reconstructed.

  • Supply structure of condominiums in Osaka metropolitan area
  • This paper aims to analyze the supply structure of condominiums in Osaka metropolitan area by examining the relationship between floor space index and unit price per m2. The A. used the method of cluster analysis. First, he focused attention
  • on chronological change in areas where construction of condominiums took place in Osaka metropolitan area during 1976-1990. He showed that floor space indexes are higher in the direction of Central Osaka and that the unit price per m2 is higher in Central Osaka
  • and the plateaux around Osaka citay and areas along the two private railways. - (KA)

  • Changes in post world war II distribution and status of monsoon rainforests in the Darwin area
  • Urban growth in the Darwin area has been recorded by aerial photography which also provides a 45-year record of vegetation change in the area. Using the available photographic records and ground surveys, this study attempts to identify the causes
  • and quantify the extent and rate of rainforest disappearance in the Darwin area.

  • Late Weichselian Periglacial landforms in the Bergsted area, north-western Zealand, Denmark
  • This paper presents various Late Weichselian periglacial landforms which have been identified in the Bjergsted area. The investigation of the periglacial landforms is an important step in the development of a comprehensive deglaciation model
  • for this area and essential for elucidating the climatic conditions during the Late-Glacial period in this part of Denmark. As a basis for the examination, a detailed geomorphological investigation has been carried out on the evolution of the present landscape
  • and consequently the glacial history of the regional area has been reconstructed.

  • On the basis of a Swiss research paper, this contribution demonstrates how and to what extent traffic areas can be minimised and the intensity of utilisation reduced. It is above all in urban areas where there is potential for savings and reductions
  • in favour of pedestrian, recreational and green areas, and thus for the benefit of the quality of urban development. - (L'A.).

  • A model of pollen source area for an entire lake surface
  • This paper describes a model for pollen deposition integrated over an entire lake surface, and it estimates the source area of major pollen types for various lake sizes. It is a modification of Prentice's (1985, 1988) model, which estimates
  • the source area of pollen deposited at a point in the center of a sedimentary basin. Comparison of the results from the two models displays the potential differences in pollen source areas when a bog and a lake of similar size are considered.

  • Soil stratigraphy and Quaternary Caliche in the Misis area of the Adana Basin, southern Turkey
  • The aim of this study was to examine pedogenic formations consisting of massive and paleosolic caliches (calcrete) in the Misis area, and to correlate these units with the underlying strata of the lithological sequence of the Tertiary Adana Basin.

  • Seed banks as a neglected area of biogeographic research: a review of literature and sampling techniques
  • The aim of this article is firstly, to review some of the relevant literature on both seed banks and methods for their study, and secondly, to emphasize the role of and need for further research within this area of biogeography.

  • Active faulting in multi-fractured seismogenic areas; examples from Greece
  • Reappraisal of existing data and evidence derived from new geological investigations illustrates the often complex association between fault geometry and seismic activity that characterise five seismically active areas of mainland Greece
  • . Morphotectonic, structural, seismotectonic and image analysis carried out in the area of the 1978 Thessaloniki (M 6.5) earthquake highlights the multi-fractured character of this seismogenic zone, previously interpreted as having a relatively simple

  • Development of Pudong and optimization of structure of urban area of Shanghai
  • Based on detailed analysis of the present situation and problems of the structure of urban area of Shanghai, the inner mechanisms that caused the problems are explored and development of Pudong as the strategic breakthrough of the optimization
  • of the structure of urban area is determined. Various restrictive factors must be considered and corresponding policies and measures must be drawn up.

  • A study on moisture conditions for winter wheat and summer maize production in the Heilonggang area of Hebei Province
  • Winter wheat and summer maize are two important crops in the Heilonggang area which is the driest part of the North China Plain. The thermal-light conditions are satisfactory for double cropping of winter wheat-summer maize, but rainfall
  • is deficient for two crops. Wheat production in this area should be restricted to a scale which is suitable to water resources conditions, while maize production can be further developed.
