This article describes the results obtained from two projects funded by the Paraiba do Sul Hydrographic Basin Committee with funds obtained through charging water users in this basin. The objective of these projects is to provide quality information to support the Committee’s decisions making process regarding water resource management. Methods included detailed spatial information development about Una river basin derived from remote sensing and GIS techniques, water quality sub-basin characterization with sixteen limnologic parameters, and integrated analysis of previous information to establish initial relationships between land use and land cover patterns and water quality characteristics. Results show that sub-basins with higher proportion of agricultural and cattle ranching associated with grassland or row crop covers are more severely affected by higher precipitation amounts as demonstrated by limnologic parameter variation.
