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.

This project aims to develop a concept for flood mitigation for the town of Simbach am Inn. It is based on the results from the event documentation and analysis on the extreme flood events on 1 June 2016 (see Report 180). The relevant designed flood (HQ100) and backwater scenarios at the outlet point into the Inn will be considered in all following work packages. A method to estimate bedload and driftwood potentials for catchments by the LfU (Landesamt für Umwelt Bayern) will be applied and validated. Followed by an analysis of required discharge cross sections, potential flood retention areas and technical opportunities for retention and filtering of bedload and woody debris will be designed. The hydraulic 2D model Hydro AS-2D is used to simulate the proposed river bed and measures concept. This results are used for an evaluation of the landscape planning proposal. According to the idea of a comprehensive risk management the following issues will be taken in account: the case of an overload, possibilities for private flood preparedness and warning systems.

Flooding is among the most expensive natural disasters in Europe. The damage of the 2013 river floods in Central Europe is € 12.900 million; the spring 2016 torrential rain events in Europe caused € 5.400 million damage. Extreme hydro-meteorological events such as river floods and flash floods will likely increase in the future due to climate change (IPCC 2014). This impacts the flood-resilience of cities. However, traditional flood protection methods provided by governments are no longer neither technically able nor economically feasible to deal with this. To substantially reduce the impact of floods on cities, besides governmental measures also individual homeowners need to make adaptations to their homes Those adaptation measures exist, but for the moment homeowners insufficiently implement them, due to their lack of risk awareness, knowledge on measures and triggers to take action. To address these issues, this project designs, tests and implements a smart governance tool – the FLOODLABEL – in urban living labs in the Netherlands, Belgium, and Austria. This prototype tool informs homeowners on their individual flood risks, assists experts in deciding upon contextualized measures for flood reduction and prevention and supports local governments in their policies on the area-based accumulated effects of individual flood protection measures.
