To understand flood risk, there are flood models of varying types and quality covering the entire world. However, it is important to remember the wisdom of George Box: “All models are wrong, but some are useful.”
What Box means is that a model is not a prediction of what will happen or a reflection of what has happened, but an educated guess about what might happen given a certain set of conditions.
In this free eBook, “Three Ways to Improve Understanding of Flood Risk” we discuss how you can better interpret flood risk from a flood model.
Floods are notoriously hard to predict because of the many factors that determine if flooding will occur, but by using multiple flood models, elevation data and historical events you can better understand potential flood risk.
