Caracterização de Voçorocas na Ilha do Maranhão
The soil erosion is a significant problem that beyond the environmental degradation, can involve risks of material damage and human lives losses, mainly in urban areas. Prevention or recovery actions are important and demands planning that consider the socio-economic urban conditions and environment...

The soil erosion is a significant problem that beyond the environmental degradation, can involve risks of material damage and human lives losses, mainly in urban areas. Prevention or recovery actions are important and demands planning that consider the socio-economic urban conditions and environmental particularities.
