This paper presents a metaheuristic approach based on the Honey Bee Mating Algorithm (HBMA) to the problem of hydropower reservoir optimization. As shortage in power resources becomes more and more pressing, the issue of obtaining more power using less primary energy resources, in general, and less water resources, in particular, becomes an important target for the efficient usage of hydropower...

This paper analyzes ownership trends of nonfederal hydropower generating assets from 1980–2003. Previous research has shown that the overall electricity industry is unique in that, because of the extreme inelasticity of demand for power, even small sectors of the industry have the potential to exhibit substantial price setting behavior. Hydropower assets especially, with their unique ability to...

Economic growth in Central Arizona, as in other semiarid systems characterized by low and variable rainfall, has historically depended on the effectiveness of strategies to manage water supply risks. Traditionally, the management of supply risks includes three elements: hard infrastructures, landscape management within the watershed, and a supporting set of institutions of which water markets a...

the greatest limitations to agricultural development and production in iran are scarcity of water resources, ineffective irrigation scheduling and wasteful water usage. avenues discussed for optimum water use include improving water productivity by improving irrigation scheduling, farm water management and water profitability. the present study evaluated current water use and ways to improve wi...

according to the current challenges toward low water use efficiency in agriculture, paying attention to the role of public participation in order to improve irrigation efficiency and effectiveness with useful methods and tools is essential. hence, approaches such as participatory irrigation management has been proposed and applied. after the primary investigation in this study, experiences of i...

The paper describes and analyses a hydropower system based on siphons in which the pressure of low-head water is converted into air pressure. The analysis suggests that, with careful design of the  ow passages to minimize losses, air-pumping efŽ ciencies of 70 per cent or more should be achievable; the overall efŽ ciency of the hydropower system should be better than 60 per cent. Although such...

the shortage of fresh water and growing competition for clear water makes less water available for agriculture production. the great chalange for the coming decades will be the task of increasing food  production with less water, particularly in countries  with limited water and land resources. therefore, increasing of irrigation efficienciy and decreasing of water losses are important factores...
