Wind Surge Modeling in the Vistula Lagoon using HEC-RAS 2D - Today’s and Tomorrow’s Perspective

This conference paper describes numerical simulations of water flow in the Vistula Lagoon using the HEC-RAS 2D (version 6.6) hydrodynamic model.The model was validated by comparing its results with previous simulations and field measurements conducted by the Polish Institute of Meteorology and Water Management (IMGW-PIB).Preliminary findings on the impact of climate change are also discussed, highlighting how an increase in wind speed over the lagoon may elevate water levels in the uawy Elblskie region and subsequently heighten flood hazard from the Vistula Lagoon waters.
