The project "development in flood prone areas: assessment of flood management alternatives" has the goal to develope integrated strategies to reduce flood risk at the federal level to support the implementation of the EU flood risk directive. Previous project have shown the necessity to analyse and to assess the various flood risk management alternatives. There seems to be also the need for an improved communication and cooperation among the various actors in this domain. The instruments should be assesed with respect to legislative and economic criteria and their potential for integrated application to reduce flood risk. The deficits of the instruments should be assessed especially in APSFR regions.

The main goal of PlasticsFatE (Plastics Fate and Effects in the Human Body) is to improve our present understanding of the impact of micro- and nano-plastics (MP/NP) and associated additives/adsorbed contaminants (A/C) in the human body. Human exposure to MP/NP may result from the widespread use of plastic products and their release to the environment, where they degrade to MP/NP particles. But plastics particles reach natural systems also as secondary by-products, e.g., from tyre wear or abrasion of textiles. As a consequence, these particles are found in food, drinking water, air and environmental media (food chain, soils). Despite recent efforts to assess the real dimension of human risks associated with MP/NP, our current knowledge is still insufficient. One of the reasons is the lack of reliable and validated methods that are able to generate the science-based data we need. PlasticsFatE will address this challenge and associated uncertainties by implementing a comprehensive measurement and testing program ("test the test"), including inter-laboratory studies, to improve and validate the performance and applicability of available methods and tools to MP/NP. The tested and validated approaches will be used to (1) identify and detect MP/NP and A/C in a variety of complex matrices, such as food (vegetables, fruits, beverages, fish etc.), human tissues and consumer products (tooth paste, beauty products), as well as relevant environmental media (air, drinking water, soils), and to (2) assess their (also long-term) fate and toxicity in the human body by using advanced cell culture and organ models that simulate real exposure to MP/NP in the respiratory and gastro-intestinal tract. The newly developed innovative approaches will be integrated into a novel risk assessment strategy specifically designed for MP/NP to provide the policy relevant and scientifically sound data needed to support the health-relevant aims of European strategies for plastics. PlasticsFatE is part of the European MNP cluster on human health.

The Liesing, as one of the three main urban watercourses of Vienna, shows in its longitudinal course a massively disturbed sediment balance and a resulting unnatural sediment dynamics. In the upper reaches, there are isolated sections of sedimentation, but downstream, due to the degree of construction, there are pronounced deficits, in which transported bed material is rapidly moved on a partially paved bed and thus cannot have a positive effect in the ecological sense (structure- and habitat-forming). The aim of the research project is to create a deficit analysis with regard to sedimentological processes and their ecological effectiveness based on a detailed as-is analysis of the sediment dynamics for certain grain sizes of the running bedload in the entire longitudinal course. Derived from this deficit analysis, framework conditions for future revitalizations are to be defined, which are to be adhered to in the course of (detailed) implementation projects in order to achieve the desired improved situation with regard to ecologically effective bedload dynamics.
