1. Tagus Estuarys Operational Model New Developments New bathymetry for Level 2 (same grid) Only tide forcing Compare with real measurements (1972) Implementation of a Level 0!

2. Level 2 – New bathymetry Running conditions: No atmospheric forcing Tide forcing in Level 1 DT = 15s Daily mean Tagus discharges (Ómnias) Validation: against water level measurements (tidal gauges) Improved data inside Estuary 1 – Peniche 2 – Cascais 3 – Paço dArcos 4 – Trafaria 5 – Cacilhas 6 – Lisboa 7 – Seixal 8 – Montijo 9 – Alfeite 10 – Cabo Ruivo 11 – Sesimbra 12 – Alcochete 13 – Ponta da Erva 14 – Póvoa Santa Iria 15 – Vila Franca

3. Level 2 – Validation Phase error due to different local hour (at same hour no lag) Mean level error: large scale meteorological influence? Level 0: North Atlantic

4. New Level 0 ETOPO 2 by METEOGALICIA Running conditions: No tide forcing Atmos. forcing : ERA40 (4 times a day) DT = 300s Validation: against water level measurements without tide (Cascais)

5. Level 0 – Validation RMSE: 0.123 m Correlation: 0.644 Current step: Run nested Level 1 without tide Error due to: Bathymetry/grid resolution Numerical dissipation Low resolution forcing ?
