Résumé
The specification of plants and of planting techniques form a major part of the activities of a landscape architect. They are critical steps towards ensuring plant survival and growth, and as such can significantly influence the overall success of a design. This thesis addressed the problems associated with specifying techniques for assisting plant establishment in dry areas on landscape projects. Irrigation, windbreaks, weed control, site preparation and planting techniques were assessed for their effectiveness in increasing the levels of available soil water. The importance of adequate site inspection and analysis was clearly identified. This enabled the design of specific solutions to the problems of planting in dry areas, using the palette of techniques covered. Practical applications of the techniques covered were shown by means of typical details. Particular attention was paid to the practice of mulching, both in research and supplementary experiments. From the work undertaken, the thermal diffusivity of a mulch appears to be a reliable indicator of its efficiency in both evaporation reduction and soil temperature modification. Loose organic mulches were found to have thermal diffusivities that were lower and less variable than inorganic mulches, and should thereby prove more effective in ameliorating the causes of dry areas than inorganic mulches.
