1 RESUMO O estudo do meio fisico de uma bacia hidrografica e condicao basica para o planejamento bem sucedido da preservacao da mata ciliar e conservacao e producao de agua. Os objetivos do presente trabalho foram analisar e quantificar a evolucao espacial e temporal (1984 e 2010) atraves de imagens de satelite Landsat-5, da sub-bacia do corrego do Cintra, Botucatu SP, processadas pelo sistema computacional IDRISI Andes, e analisar a qualidade da agua pelos parâmetros pH, CE, OD e a DBO 5 em 4 pontos distintos nos anos de 1999, 2008 e 2009. Considerando a area de 1076,48ha da sub-bacia, observou-se que a classe pastagem em 1984 foi reduzida em 25,55% em 2010 resultando no aumento das demais classes. A mais importante foi a classe mata nativa e reflorestamento, pois aumentou 5,08%, o que demonstra recuperacao da mata ciliar. Foram identificadas areas degradadas situadas no limite inferior da sub-bacia (P 3 e P 4 ) e contaminacao pontual (P 1 e P 2 ) com piora na qualidade da agua nos demais pontos nos periodos de 2008 e 2009. Restauracao e manejo de sucessao ecologica nas areas degradadas e o monitoramento da qualidade da agua nos pontos 1 e 2 serao necessarios para restabelecer a condicao natural na area de estudo.

GEOPROCESSING TECHNIQUE USED IN DEGRADED AREAS OF RIPARIAN FOREST AND THEIR CORRELATION TO THE WATER QUALITY IN A WATERSHED 2 ABSTRACT Studying the physical environment of a watershed is the basic condition for a successful planning of the riparian forest preservation, and for water production and conservation. The aims of the present study were to analyze and quantify the spatial and temporal evolution (1984 and 2010) using Landsat-5 satellite images of Cintra Stream sub-watershed, Botucatu, Sao Paulo State, Brazil, processed by the software IDRISI Andes, as well as to analyze the water quality through the parameters pH, EC, DO and BOD5 at 4 different sites in the years 1999, 2008 and 2009. Considering the 1076.48ha area of the sub-watershed, the pasture class of 1984 was reduced by 25.55% in 2010, resulting in an increase in the remaining classes. The most important class was native forest and reforestation since it had an increase of 5.08%, which indicates recovery of the riparian forest. Degraded areas were identified close to the inferior limit of the sub-watershed (P3 and P4), as well as local contamination (P1 and P2) with worsening of the water quality in the remaining sites in the periods 2008 and 2009. Recovery and management of the ecological succession of degraded areas and water quality monitoring at 1 and 2 sites will be necessary to reestablish the natural condition of the area studied.
