Groundwater provides nearly 100 % of the water supplies in some districts of Sri Lanka and is a major source of domestic water in all other districts. However, the resource remains largely neglected and invisible to society and policymakers. Groundwater offers the advantage of being a more reliab...

Better water management in irrigation tank cascade systems is vital in achieving higher productive use of available water. To develop and implement management practices aimed at improving effective use of water, studies leading to the development of models that can predict available tank water in...

Presents an improved methodology for evaluating the resource demands necessary for effective canal operations. Includes identification and analysis of three operational domains: vulnerability, sensitivity and perturbation. Enables more cost-effective strategies and procedures for operation, and p...
A global estimate of the potential for rain-fed agriculture could provide an answer to the question "How much irrigation is required?" Global studies done to date have relied on course resolution climate data (0.5-1 degree arc). In this study a high-resolution climate dataset (10-minute arc) was ...

The "Ruhuna Basins" defined for this case study encompass three of the main rivers that flow through ancient Ruhuna, including the longest and most important river in the region, Walawe. The Ruhuna basins are important in the broader Sri Lankan context, the basin being the location of a major hyd...
