摘要：This paper presents the first results of a study which investigates river basin water quality management based on theability of GIS to integrate different data sources into a common geographical database. The overall objective of thisresearch is to develop a scheme for water management and improve the likelihood of detecting water quality trends andto determine if variability in water quality parameters among a number of catchments can be explained by theirdifferences in topography, land use, soils and demographic data. The expected benefits of the research are related to theacquisition of a description of the water quality in basins using easily available data, as satellite imagery or maps, thatcan be used in regions where adequate observations are not available
