The document discusses the development and implementation of floating cities, emphasizing sustainable urbanization and ecological benefits. It highlights various projects, collaborations, and research aimed at enhancing water quality and biodiversity through innovative floating structures. The overarching goal is to create a vision for human living that positively impacts the environment while addressing urban space challenges.

Research | Water quality/ecological impact floating structures

31. INDYMO – Monitoring water quality
Visuals – Life under floating platforms
Insight into the aquatic environment.
The type of fish and aquatic organisms present and
bio-diversity, are indicators of the ecological state of
water bodies.

32. INDYMO Underwater drones | Our role
• Initiated and executed first research project with consortium
• Applied for subsidies
• Co-founded Indymo
• Brought in research and entrepreneurship experience
• Tackled big obstacle for floating developments

33. Research | Ecosystem oriented design
Positive impact in aquatic life: opportunity for the implementation of eco-measures
together with floating projects to ensure/maximize/enhance ecosystem

34. “In the Markermeer we want to connect humans back to nature. By letting them reside on water and
contribute to the ecological system in a positive way (…).
The floating homes will contribute to the water quality, habitat restoration and will offer a new
nature experience that can be a showcase for urbanizing deltas all over the world.”
The dream
Floating habitat with positive impact on the planet

35. The floating structures of buildings and piers offer the opportunity to create floating and underwater surfaces
that can be colonized by algae (1) and mussels (2). Algae extract inorganic nutrients, releasing oxygen to the
environment, whereas mussels filter the water, feeding with organic nutrients. In addition to algae and mussels,
floating helophyte filters (4) can be placed next to the platforms, removing dissolved organic matter and
diffusing oxygen through their roots. The presence of floating and underwater structures could have an effect
on the current speed and the transportation of sediments. As the current slows down, it loses the energy to
hold particles in suspension and sedimentation occurs. In areas under the floating platforms, silt could
potentially be collected (5). The dynamics and interactions among platforms, lake water and ecology should be
tested and monitored. The knowledge gained will be used to improve productivity and ecological performances
within the project.

39. Projects | Space@sea
Objectives:
1. Develop a sustainable, low cost modular floater design for multiple applications
and functions;
2. Demonstrate three business cases for different locations and applications to be
developed showing the cost reduction potential;
3. Further reduce the installation and maintenance costs of the multi-use platform;
4. Specify and conceptually design applications for the modular floater such as
Energyhub@Sea, Living@Sea, Farming@Sea, Transport&Logistics@Sea;
5. Contribute to societal acceptance of working and living on floating islands.

49.  Research-based design
• Evidence based big vision
• Not just nice pictures
 Work with policy makers and elected
officials
• Link with the ambitions of government,
make them enthusiastic
• Understand their position
• Not a blueprint but dynamic process
 Be practical and flexible
• Collaborate with partners
• Work with fire authorities, waterboards,
port authorities, utility companies
• Study technical and economic feasibility
