Lithoecology and energetics of loess: paleogeographic and genetic aspects in Lithology and stratigraphy of loess and paleosols.
  • Lithoecology and energetics of loess: paleogeographic and genetic aspects in Lithology and stratigraphy of loess and paleosols.
  • To describe loess as a complex system it is necessary to mention geographical zonation, adaptation to the landscape, and changeability under the influence of the activity of man. The distribution of porosity, moisture content and other features
  • are regarded and explained from the viewpoint of energetics. (DLO).
Normal mode energetics of the general circulation during the FGGE winter
  • Normal mode energetics of the general circulation during the FGGE winter
  • A diagnostic energetics scheme is developed in order to investigate the energy flows in the three-dimensional spectral domain in the atmosphere. This energetics scheme is applied to the data during the winter from December 1978 to February 1979.
Energetics of alpine proglacial geomorphic processes
  • Energetics of alpine proglacial geomorphic processes
  • This paper discusses the merits of an energetics approach to quantifying sediment transfer processes in the Bas Glacier d'Arolla proglacial zone, Valais, during the 1987 melt-season. Energy estimates, based on sediment transfer processes, range over
  • eight orders of magnitude. Both estimates of mass transfer and work emphasize the overwhelming importance of the meltwater channel and valley train within the proglacial sediment system. Based on energy and power magnitudes three sediment budget process
The transition of the Czech industry and its energetic and ecological consequences
  • The transition of the Czech industry and its energetic and ecological consequences
  • will be complicated. However, the rate of transformation is fast especially in the areas with favourable market conditions. The system of changes is exemplified by foreign trade and tourism. - (MS)

The energetic basis of the urban heat island
  • The energetic basis of the urban heat island
  • nombreux points obscurs, surtout en zone intertropicale. Cela tient à la complexité du système couplé ville-atmosphère, au coût et à la difficulté de mise en place de réseaux d'observation denses, ainsi qu'à une certaine carence des recherches théoriques

Households and their spatial-energetic practices. Searching for sustainable urban forms
  • Households and their spatial-energetic practices. Searching for sustainable urban forms
  • This study aims to obtain more insight into the extent to which the urban form plays a role in the household's spatial-energetic practices in order to broaden our understanding of the opportunities to achieve a more sustainable future. The study
Energetics prediction of frequency-dependent suspended sand transport rates on a macrotidal beach
  • Energetics prediction of frequency-dependent suspended sand transport rates on a macrotidal beach
  • In this paper, simple energetics modelling is used to compare velocity moment predictions with field observations of suspended sand transport rates. Separate consideration is given to transport associated with the 3 main frequency-dependent cross
  • is then used to assess the validity of this energetics approach in the prediction of cross-shore suspended sand transport fluxes.
Microclimatic variations attributable to urban-canyon asymmetry and orientation
  • The energetic response of urban canyons to variable urban geometry is investigated using the URBAN3 numerical model. Significant inter-urban canyon energy total differences are found which are closely linked to patterns of net solar radiation
  • . Implications of the study with respect to the magnitude of synoptic vs. geometric sources of urban energetic variation, and microscale and mesoscale urban modelling applications are discussed.

Holocene fluvial-coastal interactions on a mixed sand and sand and gravel beach system, North Canterbury, New Zealand
  • Holocene fluvial-coastal interactions on a mixed sand and sand and gravel beach system, North Canterbury, New Zealand
  • Fluvio-coastal interactions are examined on a progradational sand, and mixed sand and gravel beach sequence between the Ashley and Kowai rivers, Pegasus Bay, New Zealand. This coastal system presents an example of a wave-dominated environment
  • energetic enough to deal with the sediment supply derived from the rivers, but where the coast is still prograding. Its provides an opportunity to examine a prograding sand and MSG beach sequence in a non-downdrift situation.
Anastomosing rivers. Forms, processes and sediments
