These meanders are 1,2 kilometers wide. 
Preliminary measurements applied just for the 
new segments as Quehuicha sector, sazonal (turbid) 
meanders of Ucayali and the channels of Japura and 
Tapara have increased 300 kilometers the length of 
the River. 
Any measurement of table 1 increased by 300 
kilometers make the Amazon longer then 6,670 kilo- 
meters which is the acceptable length of Nile River 
everywhere in the literature. The fact that the 
Amazon would be the longest river on Earth was 
firstly issued by Schreider and Schreider (1970) and 
more recently by the Instituto Geografico Nacional 
of Peru. Our purpose is to come up with more pre-

cise figures and procedures about the total length of 
the River. These figures will arise as the Amazing 
Amazon Project advances into the knowledge of this 
huge fluvial system. 
7.FIRST RESULTS: NEW ASPECTS 
Remote Sensing data are showing very new 
aspects of the Amazon that may never have been 
refered before Figurel ( Mosaic of Amazon 
Brazilian Basin). Some of theses aspects are: 
i) The key attribute of the Amazon is the bright 
signature of the waters in the visible bands of 
Thematic Mapper sensing devices.
