Debris flows are an increasing global hazard. However, despite separate advances in the fluid mechanics, granular physics, earth sciences and geotechnical engineering communities a holistic understanding of the mechanics of these complex flows remains elusive. This proposal aims to create a “Rosetta Stone” through physical tests undertaken with common material characteristics, informed by monitored field events, leading to improved numerical models. Results will be shared, interpreted according to the different paradigms adopted within each network discipline, and communicated via an open-access repository in order to better predict runout and impact loads via improved validation and calibration of numerical models.

In rural areas, there is little adequate housing for the sustainable integration of asylum seekers, but many, partly dilapidated buildings, which have a good building structure but are not economically viable. The overall project idea is to create structures, in which asylum seekers rehabilitate these buildings for their families under professional guidance. The aim is to involve them on the labor market on the one hand and to enable them to be integrated through cooperation with local businesses on the other hand. For municipalities, value is created through the preservation of the cultural values of the buildings and active integration. In a feasibility study, labor market-relevant and socioeconomic structures within spatial planning and constructional conditions are analyzed and concrete recommendations for further implementation are given.

Currently Vienna's subway line U1 is being extended towards the south. From the station Reumannplatz, the planned line runs towards the south following a course below Favoritenstrasse towards the new stations Troststraße and Altes Landgut. The line runs up to 25m below surface and cuts through a succession of geological units. The base is formed by sediments from the Neogene which are covered by sediments of the Quaternary. These sediments are associated with fluvial terraces, which were predominantly formed by the Danube in the past. Currently a relative chronology for the formation of these terraces which form the landscape surface of Vienna exists, however, a numerical (absolute) chronology is still missing. With access to undisturbed sediments usually being very limited within the cityscyape of Vienna, the construction of the U1 offers a unique opportunity to take samples for numerical dating along a transect through a complex sedimentary succession of the Quaternary, and to promote new insight into the lansdscape history of Vienna. By applying physical dating methods, depositional ages can be determined for the sediments. In the project two independent dating methods will be applied: optically stimulated luminescence (OSL) dating, and burial age dating using cosmogenic nuclides. The aim of the project is to establish a terrace chronology for the cityscape of Vienna which will for the first time be based on results from numerical dating techniques. This may also contribute to the question if and when a tectonical displacement of the terrace bodies may have happened throughout the Quaternary.
