Mapping for urban land-use planning in southeast Queensland — a first approach

  • Hofmann G. W. 
Section 13 Engineering Geology

Summary

Since geological information for urban planning is not readily available in Queensland, a pilot study has been carried out in part of the most populated southeast of the State to define parameters for systematic mapping at the reconnaissance scale. The evaluation of land for urban use is based on capability ratings which consider slope, landslide frequency, flooding, and regolith properties, the latter with regard to foundation potential and domestic effluent absorption. These physical constraints are combined with inventories of extractive materials, groundwater protection areas, and educational geological features into a sieve map of potential urban land suitability.

Résumé

Comme les données géologique intéressant l’urbanisme ne sont guère disponibles au Queensland, une étude pilote a été effectuée dans une des parties les plus peuplées du sud-est de cet Etat afin de déterminer les paramètres d’une cartographie systématique de reconnaissance.

L’évaluation du terrain à usage urbain est fondée sur l’estimation des pentes, la fréquence des glissements de terrains, des inondations et des propriétés des matériaux du sol, ces derniers pour ce qui regarde les possibilités de fondations et l’absorption des effluents ménagers. Ces contraintes physiques ont été combinées à des données concernant les matériaux d’extraction, les zones de protection des eaux du sous-sol et des caractéristiques géologiques à but pédagogique pour former une carte d’utilisation possible des sols urbains.
