A comparison of channel erosion in small urban and rural catchments, Armidale, New South Wales
Five years after the cessation of housing construction in a small urban catchment in Armidale, the stability of the channel bed and banks was investigated with the use of erosion pins. The increased rate of erosion was the product of changed runoff
Analyse anthropogener Einflüsse auf das urbane Lufttemperaturfeld mittels eines Energiebilanz- und eines Grenzschichtmodells Analyse de l'influence anthropique sur la température de l'air en milieu urbain grâce à un modèle de bilan énergétique et un
In urban and industrial areas the anthropogenic impact on energy and mass balance and the alterations of land-surface cause the modification of the atmospheric boundary layer to the urban boundary layer. The air temperature distribution in the urban
boundary layer depends strongly on the part of evaporating surfaces of the urban area, on the amount of anthropogenic energy flux and other urban structure parameters, as the numerical simulations demonstrate. - (l'Ed.).
Validation of an estimation model for urban surface albedo
The analyses presented in this study suggest that the Arnfield (1976 a, 1982) canyon radiation model is capable of producing acceptable estimates of urban surface albedo for land-use types consisting predominantly of canyons with lengths
An urban land use analysis is carried out by a supervised classification of SPOT data (method of maximum likelihood). The scattered numbers and the small size of the green areas give them greater ecological significance and suggest a specific
analysis. In urban areas, satellite remote sensing is not used to give information about pedological conditions and of the vegetation| nevertheless, this global and synthetic approach can be useful as a tool for the organisation of specialised surveys
