Determinação da largura da faixa de acumulação de água em uma bacia da Serra do Japi.

Abstract

Serra do Japi region is considered a testimony of the native flora and fauna belonging to he Southwest Region in the State of São Paulo, Brazil, remaining from the colonization period of the country. This research proposition aims to determine topographic index values representing water accumulation areas. These areas are identified as the locus of riparian zones vegetation, as seen through the Landsat satellite in 2001. Topographic index values have been generated from land numerical model with a resolution of 10m as calculated through the IGG-SP plani-altimetric charts at a scale of 1:10.000. By crossing the topographic index chart with the riparian zones woods resulted in the minimum index values for that watershed. Results also showed that the watershed under consideration exhibiting index values higher than 10.2 correspond to riparian zones woods at Serra do Japi.
