Debris fows represent great hazard to humans due to their high destructive power. Under- standing their hydrogeomorphic dynamics is fundamental in hazard assessment studies, especially in subtropical and tropical regions where debris fows have scarcely been studied when compared to other mass-wasting processes. Thus, this study aims at systematically analyzing the meteorological and geomorphological factors that characterize a landslide- triggered debris fow at the Pedra Branca catchment...
Chemical elements, even if they occur naturally in the environment, can produce adverse health effects when ingested in high concentrations. The area is located in the Uraniferous Province of Lagoa Real, important uranium mineralizations occur, and for this reason, water containing this element and its daughter nuclides are expected. During the field stage in Caetité and Lagoa Real municipalities, 22 groundwater wells were sampled. For the uranium results, the wells represented by acronyms AC...
O trabalho investiga a potencial influência do uso do solo e da cobertura vegetal na qualidade da água dos cursos d’água da bacia do rio Piabanha na região serrana do estado do Rio de Janeiro (RSRJ). A região vem sendo degradada, ao longo das últimas décadas, em decorrência de impactos gerados por altos índices de urbanização e transformações rurais capazes de comprometer a oferta de água para consumo humano em termos de qualidade, com prejuízos para a cadeia alimentar dos ecossistemas, para ...
