Environmental disasters have occurred more frequently, especially those of origin associated with climatic conditions, generally induced by anthropogenic actions, such as floods and landslides. This work aims to present a proposal for mapping physical-environmental indicators to support the analysis of geomorphological risk in the hydrographic basin of the Parauapebas River (PA). The methodology adopted was based on precepts of the theory of ecodynamics (TRICART, 1977), supporting, in this way, the analysis of variables and criteria adopted in the estimation of the fragility of the natural environment of the environments (ROSS, 1994). Four geomorphological risk classes were identified – very low, low, moderate and high. The hydrographic basin of the Parauapebas River showed a worrying panorama in the face of the geomorphological risk, which may, in this sense, be potentiated by the accelerated and disorderly expansion of human activities.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
