“…This can be attributed to the predominance of relief being smoothly curled toward the banks of the streams. Another factor that influences erosion susceptibility as a function of slope is areas located in hills top, with slopes ranging from 10 to 30% (Saraiva et al, 2016). The shape of the terrain constitutes a qualitative variable, and from its geometry, effects are attributed that can be ordered according to their intensity, while being passive about considering the values of vulnerability to soil loss (Valeriano, 2008;Silva Neto, 2013).…”

Soil erosion is a serious environmental problem that can cause numerous types of damage to society and the environment, and thus require preventive measures. The objective of this study was to evaluate soil erosion vulnerability in the southern region of the Meia Ponte watershed, Goias, Brazil, considering two situations: natural and anthropic cover conditions. For the analysis, we used remote sensing data represented by several parameters: lithology, soil class, slope, rain intensity, vegetation index, vicinity of roads, and land use and occupation. For each variable, we established a scale of weights according to erosive susceptibility for natural and anthropogenic environments. Multicriteria analysis, which allows the combination of qualitative and quantitative information in the analysis of erosive susceptibility, was used through the relationship between soil use and land occupation. In the southern part of the Meia Ponte River watershed, the anthropic factor showed greater influence. The factors that increase erosive susceptibility were soil use and occupation, low vegetation index, and high slope. The southern part of the Meia Ponte watershed presents medium natural erosive susceptibility in most of the study area.

O planejamento ambiental é um instrumento para a gestão de bacias hidrográficas, permitindo suporte ao processo de tomada de decisões. A pesquisa teve por objetivo criar subsídios para tomada de decisão no planejamento ambiental do uso do solo da Bacia Hidrográfica Cachoeira Cinco Veados, RS. Com base no cruzamento das variáveis de perda potencial de solo (EUPS) e do balanço hídrico climatológico (BHC), obtiveram-se as classes de fragilidades para três cenários de chuvas com um limite de perda de solo pré-estabelecido. As classes mais frágeis são encontradas nas maiores classes de perda de solo e nas classes mínimas do balanço hídrico climatológico. Esses resultados nos permitem concluir a importância do planejamento ambiental continuado na Bacia, pois mesmo para cenários de perdas de solo mínimas, 1,02% da área (15,81 km2) não são permitidos de uso de acordo com os critérios adotados, ou seja, essas áreas apresentam perdas afora do limite estabelecido.
