Deriving strong rain hazard risk maps from geo-morphology
In the last summer a long time stationary rain event struck parts of western Germany leading to massive floodings especially in the Ahr valley. Such long-term stationary weather conditions get actually more and more frequent and can lead to long extreme heat or massive continuous rainfall as shown i...
