The Irrigation Optimisation System (IOS), a decision support tool and an extension of the combined hydraulic-hydrological modelling system for canal-command, is applied as a planning tool to the Mahanadi Reservoir Irrigation Scheme, a large irrigation project in Central India. Besides the MIKE 11 and MIKE SHE modelling systems, for the hydraulic and hydrological simulations respectively, it has an optimisation module to govern the canal releases. The results show that presently the canal releases are inefficient and lead to the wastage of a significant amount of water during the monsoon season. It is shown that the application of IOS reduces this wastage and results in higher irrigation intensity and physical productivity of water in the command. The case study also illustrates the capability of IOS as a planning and decision support tool.
