Description/Abstract

Trends in long-term sea level records associated to climate variability, along the NW European coast, are analysed by looking separately at the three principal sea level components; mean sea level, tides and meteorological residuals. A rise in mean sea level is confirmed for all the ports analysed. The hydrodynamic consequences of future sea level variability in the Portuguese estuarine system of the Ria de Aveiro are assessed, illustrating the importance of sea level studies. Pressure data collected show that there has been an increase in amplitude and a decrease in phase for most tidal constituents over the last 16 years.
