The Tagus River
The Tagus River is born in Spain and flows into the Atlantic Ocean in the area of Farol do Bugio, the estuary boundary. The “estuary corridor” is about 4 km wide and 40 meters deep. In this channel, the flow velocity can reach 2 m/s (7.2 km per hour). At the end of the channel, next to the sea, the speed is normally greater than 1.5 m/s (5.4 km/h), and can reach 2.5 (9 km/h) in spring tides.
