A influência dos componentes geoambientais e das intervenções antropogênicas nos movimentos de massa na sub-bacia hidrográfica do Rio Pirapora, Maranguape-Ceará

Abstract

This paper analyzes the influences of the geoenvironmental components and anthropogenic interventions to the earthflows at the watershed of Pirapora river, located in Maranguape town in Ceará state. These morphodynamic processes are closely related to the geological and geomorphological aspects, hydro-climatic conditions, the situation and physiognomy of vegetation, the geometry of the slopes and the human action that determine events of varying magnitudes. Thus, these factors may act together, especially during the rainy season, setting catastrophic events. Understanding these events that shape natural morphogenetic processes, may contribute significantly avoiding socioeconomic damage in urban areas
