Description
Flooding of river systems and deltas is the most frequent and costly natural hazard, affecting the majority of the world’s countries on a regular basis. To minimize the impact of floods, adaptation measures, mitigation strategies and financing schemes are developed at spatial scales ranging from local to global. The information needed for risk analysis and decision making varies with the scale. At a local scale, high-resolution risk assessment using specific inundation patterns is required to decide upon evacuation and mitigation plans. At a river basin scale, a more generic basin-wide assessment may be used to assist land-use planning and formulate adaptation pathways. At the global scale, international re-insurance and development organizations require a consistent risk framework for cross-continental resource allocation.
In this session, we seek to clarify what information needs on flood risks may arise at different spatial scales and what solutions are available. In particular we focus on applications in the African context. We are looking forward to contributions about, for instance:
Information needs:
- flood risk assessment requirements
- flood forecasting requirements
- temporal and spatial resolution
Solutions:
- Methodologies to provide flood risk assessments (hazard, exposure, vulnerability)
- Flood forecasting tools / examples
- Software solutions for flood forecasting / risk assessments
