The 2024 hurricanes Helene and Milton in the US, and flood disasters in central Europe in 2022 and 2024 exemplify that extreme weather increasingly spans multiple states and countries. Wider storm fronts are particularly bad news for relative low-lying communities, as excessive amounts of rain captured in larger (rural) watersheds finds its way down. In mountainous regions or densely populated urban environments, this traps people, destroys water and road infrastructure, while increased downstream flows pose great risk to properties. While much is still uncertain about the predication and impact of excessive rain volumes to regional watersheds, cities, states, and countries are diversifying and scaling up solutions to mitigate risks of extreme rain. The presentation will highlight national and global best practices and outline integrated solutions that are part of a systems approach to water management.
Learning Objectives
- Putting the 2024 US hurricane season in perspective, who and what was impacted and how can communities and assets better prepare themselves
- Outline national and international best practices in climate robust solutions, how forces of water are used for positive change
- How sustainable stormwater management and storm surge protection in coastal cities take shape through integrated planning
