During the 21st century, population growth and rising ocean levels have prompted institutional entities and, as a result, architects, engineers to study, design and propose feasible technical alternatives. Already in the past - history - we have many examples of how people have managed to develop cultures on the surface of the water. In some European cities, research strategies have already been developed to adapt to new environmental conditions, namely, coexistence of human existence with the aquatic element. Future floating cities need to be designed to cope with extreme weather events (hurricanes, thunderstorms, ripples), and, at the same time, to provide a higher, environmentally consistent quality of life to their inhabitants. The purpose of this work is to investigate the various practices of life, survival, technique, in the water, as ways of resolving the effects of rising ocean levels.
