Field research on water flows and agricultural production in the Kalankuttiya Block of Mahaweli System H was initiated by IIMI staff in mid-1985 during Yala (dry season). The primary focus was to understand the effects of irrigation management practices on crop diversification from rice to "other food crops" (OFCs) such as chili, lentil, soybean, and onion. Faced with immanent self-sufficiency in rice production, but continuing large-scale imports of non-rice food crops, the government is trying to promote the cultivation of OFCs, which require intermittent irrigation, in schemes designed primarily for rice cultivation and more or less continuous water flows.

This report documents part of an operational experiment in Kalankuttiya Block of Mahaweli System H during the 1987 yala (dry season). The experiment or "action research" was conducted by the International Irrigation Management Insti tute (IIMI) in cooperation with the Mahaweli Economic Agency of the Mahaweli Authority of Sri Lanka. The experiment was the outgrowth of studies which focused on constraints to non-rice crops during the dry season. Careful monitoring of irrigation and cropping patterns in selected areas of the system, conducted from yala 1985, had documented three important constraints to di versified crops: 1) inadequate water control at the secondary and tertiary levels of the system, 2) lack of organization for water sharing from the secondary level downward, and 3) poor conununication between farmers and agency staff regarding water delivery schedules

This paper discusses the usefulness and limitations of using the concept of Relative Water Supply (RWS) for evaluating the performance of irrigation systems, with special reference to systems irrigating rice. It then describes and demonstrates the use of a modification of RWS called Cumulative Relative Water Supply (CRWS), which can be used in conjunction with RWS. The advantage of CRWS is that it provides a measure of the cumulated RWS throughout a season, both in absolute terms at any given time, and in terms of the overall seasonal trend. It allows comparison of performance of an irrigation system or subsystem both to the target, and to other systems or subsystems. It can therefore be used both as an analytical tool by researchers, and as an operational tool by managers. The use of CRWS in conjunction with RWS is illustrated with examples from Sri Lanka.

The need to understand the technical and socioeconomic constraints in irrigation management for diversified cropping underlies this study. The main constraints identified include the unreliability and inequality of supply at the secondary and tertiary levels of the irrigation system, the lack of organization and management for sharing water below the secondary level, and the poor communication between agency staff and farmers in water delivery scheduling. Intervention studies have shown that flow measurements combined with regularly scheduled rotations and regular meetings between agency staff and farmers can enhance the management capacity of both. Because of the greater economic risks faced by farmers in growing non-rice crops as compared to rice, an assured market and a competitive price are indispensable for promoting diversified cropping.
