Abstract(s)
Urbanization alters hydrological processes and is often associated with increasing flood
risks, which threaten human wellbeing and social and economic development. The conventional
paradigm of flood protection relying on structural measures based on hard
engineering solutions (e.g., dams, piped systems) has proven insufficient to mitigate
floods. Sustainable water management, including solutions to enhance natural processes
within urban areas, is a promising approach to enhance flood resilience and
address the multiple sustainability challenges faced by cities. However, implementation
of solutions based on mimicking natural processes has been slow. Mainstreaming
of urban sustainable flood management is inhibited by governance aspects (e.g., limited
collaborative governance), and knowledge gaps on effectiveness compared with conventional engineering approaches. The increasing flood hazards driven by growing
urban populations and climate change projections of increasing frequency and intensity
of large precipitation events demand improvements in spatial planning. This
also provides opportunities for sustainable water management mainstreaming in order
to complement the relatively limited drainage capacity of conventional systems.
