COASTAL CITIES DESIGNED AS FLOOD RESILIENT SYSTEMS
A study has projected the impacts of climate change and rising sea level on the city of Hamburg for 2030 and 2085. The sea level of the North Sea, which feeds into Hamburg, is expected to rise .15 meters by 2030 and .5 meters by 2085. This will cause the water level to rise within Hamburg to .18 meters by 2030 and .63 meters by 2085.
With the driving force of climate change and rapid urbanization, a paradigm shift has occurred in flood management. Traditional flood defense management involves the building and raising of dikes and walls, cost-intensive solutions, conflict with spatial and urban planning, and entrapment. Today, integrated flood risk management incorporates non-structural measures, citizen responsibility, adaptability and flexibility in solutions, and increased governmental responsibility.
Flood risk management is based on the equation that risk equals the probability of occurrence multiplied by the consequences. Flood probability reduction measures must be made at the source of the body of water while flood resilience measures must be instituted where reception of flooding and its consequences occurs. The traditional and emergent flood resilience measures integrate 'the four A's':
The governance strategy for transitioning to a resilient city involves four phases:
- Awareness through understanding the problem and assessing current failures
- Envisioning a shared vision, capacity building in flood resilience, and strategic management and adaptation,
- Problem Resolution & Experimentation through flood resilience management within existing systems, and
- Testing & Evaluation of responses implemented and establishing a consensus.
We must overcome the obstacles of accepting living with uncertainties, and of adapting to a more integrative lifestyle.
