| Abstract: | The need to develop a framework for performance assessment of irrigation schemes is increasingly dominating discussions in the field of water management. This paper supports the view that the introduction of monitoring and evaluation of water distribution systems as a part of the day to day management activity is a desirable step in the improvement process and can be introduced at little cost.Data already being routinely collected in many schemes provide a valuable insight into scheme operation and can be used to improve planning of operating strategies. One aim of the study being carried out by Hydraulics Research and the Irrigation Department at Hakwatuna Oya in Sri Lanka is to improve the standards of main system management within the constraints of the existing physical infrastructure through the provision of timely performance data. A microcomputer has been installed at the project office to store and analyse rainfall, flow and field wetness data, and to provide performance reports on a regular basis. Early results suggest that the timely processing of an increased level of data collection is effective for both the identification of problems and the quantification of potential for improvement. Particular emphasis is given to providing the necessary software tools and training such that routine monitoring and evaluation becomes an accepted and sustainable proposition. |
