Valuation methodology of laminar erosion potential using fuzzy inference systems in a Brazilian savanna.

摘要: This study presents an approach on the evaluation of potential laminar erosion in Ribeirao Sucuri Grande watershed. It is located northeast state Goias, Brazil, a conservation area under strong anthropogenic pressure. A Mamdani fuzzy inference system was designed using linguistic variables, pertinence functions, and set rules associated to traditional prediction model through environmental conditioners slope, erodibility, degree soil protection. The with logic qualitative erosive capable being spatialized greater level detail, increasing classification by two levels. processing conditioning factors resulted values between 2.5 9.1, which places basin at low very high potential. results indicate areas that demand attention regarding management; 56.89% has medium (6.99%).
