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).
Discusses livestock water needs and the variation of water dependence in dif. circumstance, mentioning body water functions; physiological aspects of water balance; channels of gain & loss; and factors affecting water balance, particularly energy production, thermoregulation and water availability.
Deals with water resource & its exploitation in tropical Africa from an engineering point of view, giving an insight into the wide range of problems in water development & providing general guidelines for future planning.
