Hello, now we know more about our major rivers of Portugal.
Rio Minho - in Spanish and Galician Miño is an international river which rises to an altitude of 750 m in the Sierra de Meira, in the autonomous community of Galicia and travels about 300 miles to empty into the Atlantic Ocean south of the locality of the Guard and north Walk. In the last 75 kilometers of the journey, between the mouth and Melgaço, Minho serves as the border between Spain and Portugal.
The Minho river was called Minius or Baenis by ancient historians.

Douro River - a river that is born in Spain in the province of Soria, the peaks of the Sierra de Urbião (Sierra de Urbion), to 2.080 meters high and spans the north of Portugal. The mouth of the Douro is near the cities of Porto and Vila Nova de Gaia. It has 927 km long. This is the third longest river of the Iberian Peninsula.
Popular for the origin of its name are several versions. One says that comes from the Celtic dur (water). Another says that the steep slopes, river bathing dry and inhospitable shores. Rolled in it, other times, brilliant rhinestones that are found to be gold. Hence the name given to this river: Douro (the + gold).
Yet another version says that the name of the river derives from the Latin duris, ie 'hard', and stating the hardness of their tortuous contours and landscapes that crosses in particular the high cliffs of the Arribas of the Douro, in the International section of the river between Miranda do Douro and Barca d'Alva (Figueira de Castelo Rodrigo). Derivation by popular via his name romantically suggests a link to "River of Gold (D'Gold)", but this has no historical grip.
UNESCO included, on 14 December 2001, the Alto Douro wine region on the list of places that are a World Heritage Site in the category of cultural landscape.
Your course has a total length of 850 km. Develops over 112 km from the Portuguese border and Spanish and then 213 km in Portugal. Its average elevation is 700 meters. At the start of your course is a little wide and mighty river. Zamora its mouth, runs between fraguedos in deep channels. The steep slopes of the river, the tight corners, protruding rocks, violent flows, the multiple irregularities, rapid and numerous "jumps" or "points" made this untamed river.
Faced with high gap, especially in the International Douro area, where the average fall is 3m/km, from 1961, was carried out the hydroelectric Douro. With the construction of dams, reservoirs were created large tranquil waters, which came to encourage tourism and recreational navigation, as well as fishing. Excluding the periods of major floods, it can be said that the river was definitely broken.
In the national section of the Douro, installing locks in parallel with hydroelectric dams allowed the creation of a channel of river-sea navigation.
In its course from Bemposta and Perforation can be seen mirrored in its waters, all that surrounds that environment: the clouds, the sun, (burning eyes, reflected in the water), the mountains, the cliffs, the birds (ducks, herons, eagles, vultures, gulls). In the highest cliffs can be seen birds of prey, guarding their nests.
On the other hand, in the river, indigenous species such as climb, eel and trout, have been decimated by fishing or the uncontrolled and / or the modification of environmental conditions network (part of the year are near the limit of resistance of some species ). After construction of the dam was made the introduction of carp that can reach above 20 kg, it has the property to feed everything, cleaning dams even in poor oxygenation of the water. More recently, the bass, perch, pike and crayfish Red-emerged. You can still find yourself with plenty, bogue and barbel and even mussels (identical to the sea).
However, pass along the giant boulders, dyed various shades, the separation of fragments of rock, caused by sudden contractions and dilations, motivated by climate, is overwhelming.
Travelling up along the Douro that meanders between the cliffs, where you can live and / or be seen nesting vultures, griffins, eagles, wild pigeons, swallows, etc.., And the slopes of the same, partridge, turtledove, the starling , blackbird, Pope fig, etc..
Within the forests of junipers, rock roses, oaks, oaks and pines and other varieties of vegetation on the slopes of the Douro, may still find yourself game species, which are one of the largest natural riches of the region: the deer, wild boar, rabbit, hare, wolf, fox, badger, genet, etc..
The Douro river was and is a source of wealth for the region and the village. Previously, it was moving watermills that spread along its banks, such as watermills Mr. António Luís, the Fróis, the Melgos and Old, allowed fishing, irrigated fields and filled the wells of the best gardens Bemposta, near existing them, where they cultivated novelties and fruit trees, based on people's livelihoods. Later, with hydroelectric, Bemposta shall contribute to national wealth, distributing electricity to the country. Also provided greater abundance of fish through the dams, creating some jobs with professional fisheries, which were dedicated some families.

Rio Tejo - The Tagus is the longest river on the Iberian Peninsula. Its watershed is the largest peninsula in the third, after the river Douro and the Ebro River. Born in Spain - where it is known as Tajo - the 1593 m elevation in the Sierra de Albarracin, and flows into the Atlantic Ocean, Lisbon bathing, after a journey of about 1007 km.
The mouth of the Tagus left the ships and ships of the Portuguese discoveries. The wave that hit Portugal on the day of the earthquake of 1755 the river rose and flooded Lisbon and other places in the margin.
In Lisbon Tagus river is crossed by two bridges. The oldest is the 25th of April Bridge (inaugurated in 1966, then Salazar Bridge), one of the longest suspension bridges in Europe, and which connects the capital of Portugal Almada. The other is the Vasco da Gama Bridge, about 17 km long. It was inaugurated in 1998 and the league Sacavém Alcochete and Montijo.
Near Vila Franca de Gaia still exists Marechal Carmona bridge linking the two sides. It was heavily used, but with the construction of the Vasco da Gama Bridge lost traffic.
Every year at the port of Lisbon, docked hundreds of luxury liners, mostly on the dock of Alcantara. In the estuary there is an ecological reserve (Reserva Natural do Tejo Estuary) where several species of nesting birds. Due to the great river pollution no longer exist dolphins, rarely showing a specimen who mistakenly enters the estuary, returning to the sea whenever possible.

Sado River - (formerly called Sadao) is a Portuguese river, which rises 230m above sea level, in the Serra da Vigia and travels 180 kilometers to empty into the Atlantic Ocean near Setúbal. In his Alvalade route passes by and Alcacer do Sal, with the mouth in front of Setúbal. Downstream of Alcacer do Sal to the mouth develops a broad estuary separated from the ocean by the Troia peninsula. It is of the few rivers of Europe that flows from south to north.
In the Sado estuary inhabits a population of dolphins (bottlenose dolphin), which has resisted the invasion of their habitat by man (for shipping yards Mitrena, to the port of Setúbal and the resulting fishing dock and playground, plus the ferry link between banks).
The Sado River has a great flow due to several factors, highlighting two: the more arid climate of the Alentejo, where its source; and the gap small elevation between the source and the altitude of the mouth.
The catchment area of the Sado River is the largest entirely Portuguese area. The estuary covers an area of approximately 160 km ², with an average depth of 8m with a maximum of 50m. The average annual flow of the river is 40m ³ / s with a strong seasonal variability - ranging from daily values lower than 1m ³ / s in summer to more than 150m ³ / s in winter.

Rio Guadiana - or Odiana is an international river in the Iberian Peninsula, which rises to an altitude of about 1700m, ponds Ruidera in the Spanish province of Ciudad Real, in Ojos del Guadiana reborn and flows into the Atlantic Ocean, between the Portuguese town of Vila Real de Santo António and the Spanish Ayamonte. The Guadiana border between Portugal and Spain, from the river to the mouth Chança. In the section between the river and the creek Caia Cuncos the border is not demarcated due to the border dispute of Olivenza Olivenza between the creek and the creek Táliga.
The Guadiana is navigable up Mértola a distance of 68 km. In his Portuguese course was built Alqueva Dam, in the Alentejo region, which created the largest artificial lake in Europe.
