2. Sites Locations  Santos Estuary, Brazil  Bahía Blanca Estuary, Argentina  Aysén Fjord, Chile

3. Fiordo Aysén Santos Estuary Bahía Blanca Estuary Sites Locations

4. Santos Estuary  Located approximately at 24º S  Precipitation: 2000-2500 mmy -1  Mean Temperature 22º C

5. Santos Estuary Area Bathymetry Santos Estuarine System

6. Santos Estuary Inner Bathymetry

7. Hydrodynamical Features  Presents three channels (Santos, Sâo Vicente & Bertioga)  Small water exchanges through the Bertioga Channel  Watershed limited by Serra do Mar  Winds: Spring -» East  April-September -» South

8. Hydrodynamical Features cont.  Mainly forced by: Tides Tides Local Wind Local Wind Southern winds Southern winds

9. Bahía Blanca Estuary  Located approximately ~ 39º S  Precipitation: 615 mmy -1  Mean Temperature 14,9°C

12. Bahía Blanca Currents

13. Hydrodynamical Features  Mesotidal Coastal Plain (~4m Oscillation)  Various Channels, low depth  Strong Tidal Currents  Semidiurnal Tidal Wave, Standind Wave  Uniform Vertical Distribution of Oceanographic Parameters  Predominant NW winds  Several Streams Discharging  Low mean annual runoff in tributaries

14. Aysén Fjord  Located approximately ~45º S  2000-4000 mm year -1 (V. Marín)  1100-2100 mm year -1 (Caceres et al2002)  1100-2100 mm year -1 (Caceres et al, 2002)  Fresh water from at least 5 rivers; the most important is Río Aysén (700 m 3 s -1 ) all others represent (< 100 m 3 s -1 ).

19. Hydrodynamical Features  Mainly forced by tides predominantly semidiurnal  Winds very important (Caceres et al, 2002)  Steep Bathymetry (max depth ~350m)  Average width 6.5 km  Total lenght 65 km  Little affected by remote forcing generated on the coastal shelf  Wind regime Spring-Summer-»S and SW  Fall-Winter-» N and NW  Brackish water leaves leaves on the Southern part  Salty tidal intrusion goes into through the North

20. Future Steps  Get hold of the data from the partners!!  Modify and double check the Santos estuary bathymetry  Start setting the son model domains  Validate the data from this models  Chech the available bibliography for rates and constants for each area.
