4. Living with uncertainty: The tragic #Derna flood highlights the need for spatially distributed flood prevention and warning systems and Nature-Based Solutions, such as constructing dense infrastructure away from floodplains.

3. Frequency and re-analysis: The #Derna flood underscores the necessity of revisiting rain and flood return periods. Data, methods, and land use are evolving and require updates.

2. Dam Hazard: The damage caused by the dam breach was approximately 20 times greater than in a simulated no-dam scenario (the ‘natural’ flood).

1. Extreme but expected: The rain and flood magnitude in #Derna had a return period of tens of years, unlike previous estimates, which indicated a much rarer flood. 🧵

How the failure of two dams amplified the Derna Flood tragedy A new study reveals that the devastating 2023 flood in Derna, Libya, was not merely the result of extreme rainfall but was drastically intensified by a major design shortcoming and its resulting collapse of two embankment dams.

The 2023 Derna flood was intensified by the collapse of two embankment dams, highlighting the critical need for improved flood risk assessment and infrastructure planning in vulnerable regions. doi.org/g897d6

The devastating 2023 flood in the port city of Derna, Libya, was driven by the collapse of two dams rather than by extreme rainfall, according to a new study co-authored by CIRES Visiting Fellow Yuval Shmilovitz. Read the story: buff.ly/n37veAF
