Abstract: The objective of this paper is to develop and present a GIS-based and software tool capable of data management, data visualisation, and data analysis. The developed software is proved to be a good tool in the initial assessment of the quality status of the Nile river water quality. In addition a Graphical User Interface (GUI) was fully designed and implemented to make the GIS tool very easy and handy for the decision maker. Spatial analysis and visualisation of water quality data can be easily presented through the interface. It is concluded that water quality along the main stem is much better than the quality along the two main branches, where more violations are observed.
