One way to create and maintain synergy is to adopt
the concept of Adaptable
Flood Defences, also called the AFD concept. This concept has the potential to achieve physical synergy
between urban functions and the technical function of flood protection.
The AFD concept provides innovative structures
which combine urban functions
and the technical function of flood protection into one multifunctional structure. Structures like car
parks, buildings, dwellings and roads are designed or transformed with the
additional capability of protecting the hinterland against floods. The
presence of the flood defence in the urban riverfront is no longer seen as
degradation, but as a contribution
to the urban quality.
Creating physical synergy in an urban riverfront
by adopting the AFD concept
should not be a snapshot, but a sustainable affair. It is therefore important to take the aspect of time into
account. The feature ‘adaptability’ of the AFD concept enables flood controllers to
cope with the uncertainties of external influences like climate change or
economic change and to extend the technical lifespan of flood retaining
elements. Adaptability of urban elements enables urban planners to
anticipate on changes in desires on urban activities and to extend the technical
lifespan of urban elements.
