Special Sessions



Floods, Droughts and Climate Change (FDCC)

Short description on the session:
During the last months, extreme floods such as the July 2021 catastrophic flooding in Germany, Belgium, and China, and the monsoonal disaster in India have been recorded worldwide and are hitting global news headlines. Increasing human suffering, economic costs and damage to intangible values linked to floods are indeed emblematic of current weaknesses in predicting and managing flood risk. On the one hand, we are faced by the occurrence of more extreme climate-related events, transformations of rural landscapes and unsustainable urban population growth, which continuously changes the boundary conditions at which flood risk models must be adapted to deliver reliable results. On the other hand, our efforts are frustrated by limitations in our modelling capabilities.

The session “Weak points in the flood risk modelling chain” is linked to the homonymous initiative, recently launched by the Flood Risk Management Technical Committee of IAHR (https://www.iahr.org/index/detail/337). Objective of the initiative is to offer a platform to experts from academia and professionals to share their experience in flood risk modelling, to discuss about present limitations, with the final aim of improving our modelling and risk mitigation capabilities.

With the initiative we are collecting contributions on: (i) identification of weak points/limits in the flood risk modelling chain; (ii) tools, best practices, bench mark data sets and case studies that could support our researcher and practitioner communities in dealing with those shortcomings.
In this framework, the session has a twofold aim: highlighting contributions received so far and collecting new ones with the ambition of widening the database.
