- Abstract:
- Urban areas face new challenges through changing climate. One aspect is the uneven distribution of water and the handling of such. While green infrastructure and its ecosystem services are suffering during periods of drought and high temperature, stormwater events exceed the capacity of central water management facilities. Negative impact on health, ecosystems, biodiversity as well as communities budgets need to be tackled. To foster development, the City of Vienna collaborated with the University Natural Resources and Life Sciences Vienna on research for the combination of technical substrates with specific plants. Research issues concern geotechnical and vegetational aspects regarding normative guidelines. This covers infiltration and carrying capacity for substrates and growth, vitality, vegetation coverage, salinity in foliage and stress reaction to heat for the vegetation. The set up on three sites in Vienna included 15 substrates, 27 trees of six different genera and three varieties of seed mixtures. Substrates included existing soil, standard tree substrate and especially composed SAVE substrates. From March 2019 to December 2019 the different parameters were monitored within a fixed timeframe. The data were documented per test site and formed the basis of the master matrix, where the performance of the parameter got evaluated in the geotechnical and the vegetational field. The result was a ranking of substrate-vegetation-combinations through a point system, determining the best performing combination. The results show that the best overall performance of substrate and vegetation happen in combination with SAVE substrate variants, inducing new possibilities for decentralised stormwater management.
