- Abstract
- Salima fluvial flood risk 50 years return period probability generated as part of Northern region and Lake Malawi Flood risk management project by RASOR (rasor-project.eu) for Global Facility for Disaster Risk reduction and the government of Malawi between June 2015- June 2016. RASOR has developed the flood risk model by adapting a newly developed 12m resolution TanDEM-X Digital Elevation Model (DEM) to flood risk management applications and using it as a base layer to interrogate data sets and develop specific flood disaster scenarios. RASOR overlays archived and near-real time very-high resolution optical and radar satellite data, combined with in-situ data for Malawi local applications. The probability of a flood event occurring is expressed as a return period. A flood return is the inverse of probability (generally expressed in %), it gives the estimated time interval between events of a similar size or intensity. For example, the return period of a flood might be 50 years; otherwise expressed as its probability of occurring being 1/50, or 2% in any one year. This means that, in any given year, there is a 2% chance that it will happen, regardless of when the last similar event was.
