Sri Lanka is a country with vast spatial and seasonal variations of water supply and demand. Statistics in the form of aggregated information at national level sometimes mask issues of local water scarcity. But when the same indicators are used at subunit level, a substantial area of the country comes under severe water-scarce conditions. Knowledge of subunit level water scarcities is very important because most of the food requirement of the country at present comes from water-scarce regions and projected additional requirements are also to be met by the same regions.

Evaluates the performance of the Bhadra Reservoir Project-before, during, and after the introduction of modernization with structured system design. Analysis focuses on water management, agricultural productivity, and farmer participation and perception. Identifies the absence of a continuing support mechanism and lack of farmer participation as the major causes for the project's decline.

Studies the low-cost alternative strategy of selective lining of watercourses to reduce seepage and increase irrigated areas in the Indian subcontinent. Satellite remote-sensing (SRS) is seen as a cost-effective evaluation tool in view of its large area of synoptic and repetitive coverage.

Coping with scarcity of water supply for managing irrigation under uncertain and inadequate conditions has become part and parcel of many irrigation systems in the semiarid tropics of Asia. Based on a case study of the Kirindi Oya Irrigation and Settlement Project (KOISP) in southern Sri Lanka, this report provides evidence of the uncertain and inadequate inflow into the reservoir and its impact on the seasonal planning.

Assesses the impact of rehabilitation interventions on irrigation system performance using time series analysis. The study demonstrates that with proper impact specification and model identification, the nature and magnitude of the impacts of different interventions can be separated from the effects of simultaneous changes in dominant exogenous factors.
