Floating Cities: ‘we have a dream to realize’ A fundamental new approach to urban development is needed for the challenges of the 21st century. Floating houses and cities can accommodate future urbanization without sacrificing land and provide a sustainable living.
Study on water quality and ecological impacts/potential However, the implementation of floating cities is facing barriers. As a research group we will determine the pro’s and cons of floating structures and come with a design tool with recommendations for design, construction and maintenance. For example: • we will find solutions for potential effects on the water quality due to floating life • good design to mitigate hydraulic resistance in channels • get a strong international alliance for knowledge exchange on floating structures
Knowledge exchange • How to share this knowledge? • How to reach stakeholders? • How to speak a multidisciplinair language?
