• Abstract

  The triggering of landslides by the reduction of suction (unsaturated condition) from the infiltration of rainwater is one of the main mechanisms of instability in tropical and subtropical areas in different countries, often causing significant social and economic damages. In Brazil, several researches were developed focusing on these processes and mainly studying colluvial soils and resi…

  Application of slope stability analysis models in a GIS environment to predict landslides in the Serra do Mar region, SP, AP.R

• Abstract

  In the last years, the frequency of landslides is increasing in entire Brazilian territory. These processes have induced different kind of damages to the population that live near of the slopes. The landslides are controlled by natural factors and they can be directly triggered by a wide range of the human influences. In Brazil, the researches available about this topic are concentrated i…

• Abstract

  Intense precipitation is a triggering factor of dangerous hydrological and geological events, such as floods, erosion and mass movements. Frequently, such events are responsible for economic and social losses. Therefore, the study of the relationship between rainfall and the occurrence of this kind of event is key. Since intense rainfall is a ruling element for dangerous events to occur, …
