Short summary
This paper investigates the hydrodynamic processes among the interconnected water bodies (river branches, lagoons, and the coastal sea) that together form the Danube Delta river-sea continuum. To achieve this, we implemented the SHYFEM (System of HydrodYnamic Finite Element Modules) model across the entire Danube Delta. The model was applied to investigate the distribution of water among river branches, coastal dynamics in front of the delta, the renewal capacity of the lagoons, and the potential impacts of lagoon-sea reconnection solutions.
