SUMMARY:

Transverse drainage comprise counterintuitive rivers that discordantly cut across surfaces such as ridges, plateaus, cuestas, mountain ranges, and horsts, forming canyons, gorges, or water gaps, whose formation is attributed to different morphogenetic mechanisms. Several studies on transverse drainage systems have been conducted in tectonically active regions, however, in tectonically quiescent margins, these studies are still scarce. In the semi-arid region of Brazil, especially in the northern Northeast, several drainage perpendicular to the regional morphostructural context with a predominantly NE-SW direction are identified, cutting across reliefs developed in different lithologies, forming canyons and epigenetic gaps. However, even with the high amount of neotectonic, seismic, stratigraphic, and paleoclimatic data produced in recent decades, there is a scarcity of studies about the evolution of these drainage. Given this, this research aims to understand the importance of morphostructural, morphotectonic, and morphoclimatic factors in conditioning transverse drainage mechanisms in the upper course of the Seridó River basin. To this end, field surveys, a literature review, and the application of morphometric metrics and parameters (e.g., drainage density, lineament density, Chi analysis, Gilbert metrics, Normalized Channel Steepness Index, knickpoint extraction, and low-relief surface mapping) were carried out.
