Increased population exposure to Amphan-scale cyclones under future climates
In 2020 Cyclone Amphan made landfall in the Bay of Bengal and was the first super tropical cyclonic storm to occur in the area in over 20 years. This paper explores what would happen if this event were to occur in the future, asking: would the risks associated with it change?

Flood Inundation Prediction
This review surveys recent progress made to address fundamental issues surrounding globally consistent mapping of flood hazard in underdeveloped countries. This is achieved through a novel combination of appropriate physics, efficient numerical algorithms, high-performance computing, new sources of big data, and model automation frameworks.
