The development of river basin policy and management plans involves a spectrum of concerned parties and organizations, only a small fraction of which are represented by technical professionals. Easily-used and highly-interactive computer simulations provide a means by which these individuals can develop both a conceptual and an intuitive understanding for the complex physical behavior of river systems. NileSim is a graphical simulator of the complete Nile River Basin, which has been developed principally for the pedagogical purpose of explaining complex river behavior and management to non-technical people. The simulator has been developed in a cost-effective manner, making use of modern software development tools from electronic design automation. This has provided a rigorously accurate tool, which is fast, graphically intuitive, and simple for people to use. The tool supports interactive experimentation with a simulated Nile River Basin for users to learn by observation how that basin system works.

The United Nations Environment Programme (UNEP) has reviewed NileSim (pp. 51-54) in its report “Water Sharing in the Nile River Valley“, carried out under its Project GNV001: Using GIS/Remote Sensing for the Sustainable Use of Natural Resources.
