Challenges in modeling the Danube delta hydrodynamics by Lauranne Alaerts

The Danube delta, largest nearly undisturbed wetland in Europe, serves as a vital buffer between the Danube River and the Black Sea. Despite its ecological significance, it remains largely understudied. Hydrodynamic modeling offers a valuable means of exploring the delta's dynamics and its interactions with the Black Sea. However, the lack of comprehensive data presents a significant challenge to this approach. In this presentation, I will discuss bathymetry (i.e. depth) reconstruction, emphasizing the pivotal role of data quality and distribution. Additionally, I will present preliminary results that highlight the importance of integrating flood plains into hydrodynamic models to better represent the Danube delta hydrodynamics.
