 In: Colombo (Sri Lanka). IIMI. 1996. 18 pSummary: The IIMI water balance framework (IWBF), which is in Excel, is an easy-to-use computer model for analyzing the utilization of water from surface irrigation and rainfall within an irrigation project. The framework allows explicit definition of losses to seepage, operational losses, and efficiency of field application. Recycling of water through pumping from drains and from groundwater is allowed, and the resulting water balance is presented, showing flows to groundwater, outfalls from drains, and consumptive use of crops and other evaporative uses. The model permits a simple validity check of basic assumptions to ensure approximate internal consistency. Where such consistency cannot be demonstrated, either through this model or a more complex formulation, the impact of changes in management or infrastructure cannot be predicted
