DuneFront will demonstrate blue-grey coastal and marine infrastructure as a new generation of sustainable, inclusive, and aesthetic solution to ensure coastal safety under climate change. The project has the ambition to co-create hybrid Dune-Dike Nature Based Solutions (DD-hybrid NbS) that can efficiently integrate static hard infrastructure with adaptive, dynamic aeolian and vegetated sediments. Mainstreaming biodiversity into marine and coastal DD-hybrid NbS is essential to jointly safeguard human assets, blue economy activities and biodiversity gain and restoration. DuneFront will achieve this challenge by identifying key biological, physical, and socio-economic boundary conditions, and by translating evidence on biodiversity, morphodynamics and safety from 12 Demonstrators along vulnerable European coasts into new roadmaps for DD-hybrid NbS design and installation. The integration of this multidisciplinary knowledge into physical and digital twins will pilot the development of a Decision-Support-System, coastal and marine infrastructure Blueprints, and the installation of new prototypes along one of the most recreated coasts. DuneFront will provide a wide range of stakeholders with design, installation and market-ripe business plans for DD-hybrid NbS. Translation of new research and innovations into the DuneFront targeted actions will occur within a full co-creation-procedure.

The Danube River has played a vital role in supporting both human and animal life for centuries. Since the late 19th century, human interventions have significantly altered the natural flow of the river to optimize its utility. These interventions have included actions such as straightening the riverbed, constructing hydropower plants, collecting freshwater, establishing nuclear power plants, engaging in agriculture, and facilitating navigation. The combined effects of climate change and extensive river regulation have led to a significant disruption in the natural balance of sediment in the Danube River, increasing flood risks, altering hydropower production, decreasing navigability of the river, and affecting in biodiversity within the Danube Basin. SUNDANSE will: • carry out a conceptual Driver-Pressure-State-Impact-Response with multiple levels of analysis (catchment level, water body level, etc.) to understand and address environmental issues of the uniqueness of Danube river lighthouse • realize maps for observation of critical points for excessive sedimentation and/or excessive erosion, sediment transport and flow restoration • perform innovative actions of measurements using cutting-edge portable on-vessel equipment prototypes for the direct analysis of microplastics and toxicity • achieve an advance numerical prediction model of sediment transport process in the Danube River basin, to have a comprehensive overview of river dynamics • develop an Innovative Sediment Management Framework for enhanced and sustainable sediment management within the Danube River basin • produce an Action plan and Roadmap for associated regions to upscale demonstrated sustainable and effective solutions for sediment management • fulfil interconnections synergies with DanubeSediment and SIMONA projects and ICDPR initiatives • improve the trans - national and cross - sectorial cooperation, contributing to a better governance in region and to implementation of EU strategi
