Geotechnologies present as an important tool in identifying vulnerable areas, assisting in land vulnerability mapping, allowing the spatial distribution of risks caused by soil loss. This study aimed to identify and diagnose the vulnerability of the soil in the Lajeado Pessegueiro watershed, Guarujá do Sul, Santa Catarina State, Brazil, based on the strengths and weaknesses of the environment, to provide input for the planning and environmental and economic management. The vulnerability mapping was developed through integrated environmental analysis with many variables and with the use of a geographic information system that allows the spatial distribution of risk through thematic maps, which can assist in the planning and management of the river basin and farms placed in it. The methodology uses the delimitation of landscape units, and assigns to each thematic variable a value of stabi...
