This study of irrigation management and crop diversification is being carried out under a Technical Assistance Agreement (T. A. No: 846 SRI) dated 27 November 1987, between the Government of Sri Lanka (GSL), the International Irrigation Management Institute (IIMI), and the Asian Development Bank (ADB). The study is being implemented by IIMI in the Kirindi Oya and Uda Walawe projects in the southern part of Sri Lanka in close collaboration with the agencies in charge of development and management of these projects. It addresses, through field-level research, priority issues of importance and relevance to the two projects in the processes of irrigation system management, with particular attention given to the requirements of crop diversification.

This paper is a substantially revised version of a draft paper previously circulated to some officials in Sri Lanka. The title of that paper was "Testing a New Field Channel Design: A Pilot Project of the Uda Walawe Rehabilitation Project, Sri Lanka. It was reviewed by the International Irrigation Management Institute (IIMI) - Sri Lanka Consultative" Consultative Committee at its January 1988 meeting; as the minutes of that meeting indicate, the Committee members recognized- the significance of the main findings of the draft report, and agreed that physical rehabilitation by itself could be counter productive unless supported by proper institutional changes. The paper is based on periodic observations (approximately weekly) of farmers' use of a rehabilitated pilot field channel (FC), and interviews with both farmers and field level officials, over two seasons in the Uda Walawe Scheme, Sri Lanka.

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.
