Irrigation Canal Simulation Model (ICSM) is a management and diagnostic tool in water management of open canal irrigation schemes. It is being adopted for efficient water management in large irrigation schemes in developed countries. The basic components of ICSMs and their development were reviewed with the focus of presenting their principles and procedures. The key issues on how to simulate water flow in irrigation canal and the prevailing conditions that can allow such issues to be studied and quantified were analysed and linked with the requirements and practical uses of the ICSMs. The applicability of such tool to the South Africa irrigation schemes was also assessed. The need for the experts to be drawn from research institutions like Dept. of Water & Environment, Council for Scientific and Industrial Research (CSIR), Agricultural Research Council (ARC) and Universities to initiate the process of developing a friendly ICSM was suggested, as this will help in the management of the schemes judging from the enormous cost investments. The cost effectiveness in terms of time, energy, human and materials resources savings are among the advantages for their adoption.
