Circulation and Transport Processes during an Extreme Freshwater Discharge Event at the Tagus Estuary

During the winter of 2013, Tagus estuary was under influence intense winds and extreme freshwater discharge that changed its hydrodynamics and, consequently, salt heat transport. Moreover, dynamics may change due to climate which will increase frequency waves mean sea level. Therefore, it is utmost importance study impact future in air temperature level events, such as ascertain foreseen changes water properties transport within near coastal zone. Several scenarios were developed explored, using Delft3D model suite, considering results CMIP6 report forcing conditions. Before event, mixing region presented well-mixed conditions marine area a slight stratification. filled with migrated toward coast, leading lower values inside estuary. SLR has higher on salinity stratification patterns than increase. The response directly related temperature. mouth shallow regions be more prone upstream projected are linked CO2 emissions scenarios, being intensive highest emission scenario.
