Hamza River

[2][3][4] The unofficial name is in honour of Indian scientist Valiya Mannathal Hamza, of Brazil's National Observatory,[5] who has undertaken research on the region for four decades.

A combination of seismic data and anomalous temperature variation with depth measured in 241 inactive oil wells helped locate the aquifer.

East–west trending faults and the karst topography present along the northern border of the Amazon basin may have some role in supplying water to the "river".

The evidence was presented at the 12th International Congress of the Brazilian Geophysical Society in Rio de Janeiro and as of August 2011 has not yet been published, although the research team noted that the techniques used to predict the flowing aquifer's presence are not unusual for earth science.

[7] Scientists have explained that the research results are preliminary, and that the definite scientific validation of the existence of the flowing aquifer is to be expected in a few years.
