IDENTIFICAÇÃO DA FRAGILIDADE DAS DIFERENTES PAISAGENS NA ÁREA DE CONTRIBUIÇÃO DA REPRESA DO IRAÍ

The study area is located in the Iguaçu river basin, more precisely, in the contribution basin to the Iraí river's dam. Is located among the coordinates UTM of 685 Km to 705 Km W and 7180 Km to 7200 Km S, central meridian 51st, south 22. The work had as main objective to identify in the agricultural atmosphere inside of the area of contribution to the Iraí river's dam areas of larger fragility, being used as referencial the determination of the fisionomy units. They were identified six (6) units through the interpretation of the produced image by IHS transformation. It was used multiple criteria evaluation in geoprocessing atmosphere to determinate the fragility. Palavras-chave: GIS, fragilidade, lago Iraí
