Social aspects of water management during the Maha season 1985/86 in Dewahuwa and Mahaweli H-2 Block 305: precept and practice
The International Irrigation Management Institute (IIMI) began research projects in Dewahuwa Tank and Mahaweli 11-2 during the Yala season (May-Aug.) of 1985. The research focussed initially on agricultural economics (e.g., farmers' use of agricultural inputs and returns from different crops) and on irrigation engineering (water distribution and flow rates).
