With widespread concern over the comparatively low levels of performance of irrigation systems throughout Asia, attention is focusing on rehabilitation rather than on construction of new systems. Rehabilitation looks at both redesign of physical infrastructure and improvement of managerial capabilities. This paper points out, however, that managerial inputs can only be effective if the physical infrastructure has sufficient flexibility to accommodate managerial demands. The paper focuses on three case studies in the Philippines. The case studies have been selected to demonstrate how managerial considerations for improved system operation have been constrained by the design of the physical infrastructure at primary, secondary, and tertiary levels within the system. The main conclusion that can be drawn from these case studies is that changes in system operation can only be successful if redesign of the physical component of the system is fully integrated with operational criteria at the onset of the rehabilitation process.

The effects of location and hydrologic factors on drought occurrence in the 5,700 ha command area of a lateral in the Philippines' Pe$aranda River Irrigation System were studied. Greater moisture stress was observed on fields located further along major canals. Minimum water requirements for rice increased substantially when fields were allowed to dry out and crack during periods of water scarcity because of increased seepage and percolation through the cracks when water was resupplied.

The paper discusses the interrelationship of design (and construction), operation, and performance of irrigation systems. Specifically, it (1) describes the farm-level effects of design (and construction) and operation on the performance of irrigation systems; (2) identifies the factors leading to ineffective use of farm-level facilities by farmers; and (3) recommends additional criteria for the design and operation of irrigation systems. Arguments from Philippine case studies that evaluated alternative designs of farm-level facilities and approaches to improve equity in water allocation and distribution in a modern traditionally designed run-of-the-river, reservoir-backed, and pump-based irrigation systems are used. The general conclusion is that in both the traditional and modern systems, improvements in water management at the main system can improve water distribution equity and increase irrigated area as well as crop yield. But improved management in the main system often becomes difficult, if not impossible, because of some technical inadequacies due to deficient irrigation system design and construction.
