Scientists have spent centuries debating where the source of the Amazon River begins but now they say they have finally found it at the Mantaro River, which runs through Peru.

A new study by the University of California has revealed that while the definition of "source" has not been established, researchers explained that it is "the most distant point up the longest tributary in the river's drainage basin," National Geographic reports.

Topographic maps, satellite imagery, GPS tracking data and digital hydrographic datasets were used to the chart the Mantaro and determine that it was around 10 per cent longer than the Apurimac River, which was wrongly attributed as the source since 1971, Fox News reports.

But according to the Daily Mail, some geologists argue that the Mantaro runs dry for five month of the year meaning it cannot be the source.
