ii) To map the turbid waters is to follow all the 
rivers of the Amazon that are born in the Andean 
Ridge like: Putumaio-Iça, Japura, Napo, Marañon, 
Ucayali, Jurua, Purus and Madeira (figure 1). 
iii) The turbid waters gather weathered sedi- 
ments from the Andean Ridge exclusively. 
iv) The rivers with clear waters (Tapajos, Xingu 
and Tocantins/Araguaia) are not bringing to the 
Amazon any coarsed sediments because there are no 
more mountains in Brazilian Central Plateau. Some 
parts of Xingu and Tapajos are turbid due to gold 
miners (garimpos) (figure 1). 
v) The black rivers of the Northern margin 
(Negro, Uatum,,, Trombetas, Paru and Jari) do not 
bring any coarsed sediments either. They are full of 
organic matter washed from the leaves(figure 1). 
vi) The main purpose of the Amazon System is 
to modelate the Andean landscapes and wash the 
Ridge into the Atlantic. 
vii) Part of the sediments are being (and has 
been for thousands of years) gathered by the River 
into the Atlantic until to reach the Eastern coast of 
South America from Northern Amapa to French 
Guyana and probably Georgetown (figure 2). 
viii) Sediments of the River were registered by 
Remote Sensing devices at least 120 kilometers off 
Cape Norte in the coast of Amapa. 
ix) Muddy banks and silting waters of Amazon 
origin are the main features depicted in LANDSAT 
images of Cayenne and Kourou. The muddy banks 
with shrub cover appeared as green color and silting 
waters are greenish blue (figure 2). 
x) The same features are observed in the images 
of Paramaribo and New Amsterdam. 
xi) The Georgetown swamps and mangroves that 
were dried and moved to cropfields (sugar cane and 
rice) can be correlated to the Amazon sedimentation 
process since the banks and the waters show the 
same signatures as the features depicted in the 
images of Paramaribo and Cayenne.

xii) To our model the source of mud and silt that 
are designing new features in the Northeastern 
South America coastline is the Eastern landscapes of 
the Andean Ridge more than 7,000 kilometers away,
