abstract = "The Land Use Land Cover (LULC) of reservoirs drainage areas can
impact its water quality. Therefore the use of remote sensing
techniques to evaluate de LULC associated with limnological data
collection contributes to a better understanding of the
spatial-temporal dynamics of water quality in these water bodies.
This study aimed to evaluate the relation between the watershed
LULC and the trophic state in the Funil reservoir, located in the
Paraiba do Sul River Valley, one of the most industrialized
regions of Brazil. The analyses were carried out using
Landsat-5/TM images, limnological data collected at different
seasons, and a geographic information system. A trophic state
index (TSI) was calculated based on total phosphorous
measurements. Preliminary results showed that from the temporal
point of view, the reservoir has high TSI (i.e., lower water
quality) during spring and winter months. From the spatial point
of view, the reservoir showed low TSI (i.e., better water quality)
in the region near the dam. The spatial and temporal dynamics of
TSI in Funil reservoir is related to the LULC of its watershed,
which is predominantly agricultural.",
