             abstract = "Understanding the factors that controlled the development of large 
                         rivers lacks information from modern and ancient analogues. The 
                         Amazonian basin contains several of the largest rivers on Earth, 
                         with many having tectonic control. The study of these rivers can 
                         contribute to test the claim that large rivers have a tectonic 
                         forcing. Addressing the evolution of the Juru{\'a} River is 
                         relevant, since this is the longest Amazonian river that parallels 
                         the Solim{\~o}es Megashear Zone, a major NE-striking structure 
                         with a long history of reactivation of faults and folds even in 
                         the Cenozoic. This work discusses the geological evolution of the 
                         Juru{\'a} River along the Pleistocene-Holocene based on digital 
                         elevation models, integrated with subsurface data (well log and 
                         seismic reflection). The goal was to characterize some ancient 
                         large river valleys in forested areas of Amazonia and to analyze 
                         whether they might be related to previous paths of the Juru{\'a} 
                         River. A physical connection was found between this river and 
                         three elongated belts (i.e., PV1, PV2, and PV3) with low 
                         topographic and dissection values and surfaces marked by sinuous 
                         to meandering strings or curved lines. These characteristics led 
                         to relate the belts to ancient Juru{\'a} River valleys, an 
                         interpretation also suggested by the correspondence between 
                         paleovalley morphologies and subsurface Pleistocene-Holocene 
                         deposits with concave-up erosional bases. A tectonic hypothesis 
                         could explain the development of these paleovalleys around 
                         drainage basins with an annular pattern associated with a large 
                         convex-up relief, which we relate to rock upwarping by folding. 
                         Reconstructing the geological evolution of the Juru{\'a} River 
                         can introduce new data in discussions focused on the origin of 
                         large tropical rivers and on the neotectonic history of the South 
                         American intraplate.",
