ARCHAEOLOGICAL LICENSING AND HIGHWAYS: ARCHAEOLOGICAL, GEOENVIRONMENTAL, AND CARTOGRAPHIC CHARACTERIZATION OF THE ÁGUA SUJA 1 AND 2 SITES IN MARINGÁ (PR)

Abstract

This paper presents the results of archaeological salvage at the Água Suja 1 and Água Suja 2 sites, located within the area directly affected by the Southern Metropolitan Bypass project of Maringá. Research was authorized by IPHAN, and fieldwork was conducted in 2024. The sites lie in an inter-basin corridor linking the Pirapó and Ivaí rivers, a landscape historically conducive to past human movement. The methodology combined controlled excavation (test pits, area stripping, gridding; artificial/natural stratigraphic units) and geospatial recording using GIS, GPS (UTM, SIRGAS 2000) and UAS (drones), producing orthophotos/orthomosaics and DEM/DTM. Based on the regional archaeological context and techno-typological analysis of the assemblages, we infer the possible presence of pre-ceramic hunter-gatherer groups and later reoccupation by Guarani ceramic groups.
