A perspectiva acadêmica brasileira sobre os aspectos essenciais para a representação geomorfológica em escala de detalhe

Abstract

The 1960s were marked by meetings between geomorphologists from different countries, resulting in guidelines that became the basis of geomorphological cartography. In Brazil, these trends were introduced at the end of the 1960s and influenced the experiences developed in the 1970s. However, from the 1980s onwards there was a predominance of comprehensive mapping coordinated by government institutions, while detailed mapping was carried out by research groups in a decentralized manner. As a result, detailed geomorphological mapping began to be developed from different and theoretically heterogeneous perspectives. The aim of this note was therefore to record Brazilian researchers' conceptions of the essential aspects of large-scale geomorphological representation in Brazil and to relate them to international understanding. To this end, a consultation was carried out via a digital form with the Brazilian geomorphological community. This consultation reached 45 researchers with technical and scientific experience in the field. It was found that the elements most of them need to understand are morphometry, morphography, morphodynamics, morphogenesis and hydrography. Lithotypes and morphochronology were pointed out as necessary by 42% and 37%. In this way, the national academic perspective is out of step with the consolidated international understanding.
