Environmental management and planning problems cover important real life areas. These problems may include the scarcity of groundwater resource, the optimality of a multi-reservoir system, the management of forest resources, the air quality monitoring networks, the municipal solid waste policies, etc. Management and planning targets by authorities consist in allocations at appropriate places an...

Ethiopia is growing fast, and the country has a dire need of energy. To avoid environmental damages, however, looking for green energy polices, including hydropower exploitation, with large water availability (i.e., Blue Nile, greatest tributary Nile river). Besides other dams on Omo river, GIBE family, now building largest plant Africa, GERD (Grand Ethiopian Renaissance Dam), leading to tensio...

Standard operating policy and hedging policies are commonly used for reservoir operation for municipal or irrigation water supply. Application of these policies to hydropower reservoir operation is complex. In this paper, new standard operating policies and standard hedging policy are proposed for hydropower reservoir operation. The newly proposed policies were applied to the operation of Indir...

Today, with the great development of science and technology, it seems to be more and more important to develop renewable energy sources. In this thesis, I would like to introduce something about Chinese water resources. The renewable energy sources can generate electricity. Furthermore, hydropower is the most often used energy in the world. Hydropower develops quickly in recent years in China a...

Sustainable development is a shared responsibility. Accelerating sustainability of water–energy–people nexus and building a common awareness of issues pertaining to sustainable development are essential for any sort of success in this direction. Hydropower has been a useful sustainable energy for development, yet highly controversial. This paper reviews the overall situation of hydropower devel...

The benefits of potential electric power transfers between the Pacific Northwest (PNW) and California (CA) are evaluated using a linked set of hydrologic, reservoir, and power demand simulation models for the Columbia River and the Sacramento–San Joaquin reservoir systems. The models provide a framework for evaluating climate-related variations and long-range predictability of regional electric...

Sustainable use of the freshwater resources of the world is an urgent challenge. The World Health Organization recently estimated that 1.1 billion people lack access to safe drinking water, a problem the United Nations highlights in its Millennium Development Goals. To address the scale and urgency of this challenge, IBM, The Nature Conservancy, and the Center for Sustainability and the Global ...

Information hidden in the characteristics and relationship data of a cascade hydropower stations can be extracted by data-mining approaches to be operation rules and optimization support information. In this paper, with Three-gorge and Gezhouba cascade hydropower stations as an example, two operation rules are proposed due to different operation efficiency of water turbines and tight water volu...

The effects of development and the uncertainty of a changing climate in eastern Africa pose myriad challenges for water managers along the Blue Nile. Sudan’s large irrigation potential, hydroelectric dams, and prime location within the basin mean that Sudan’s water management decisions will have great social, economic and political implications for the region. At the same time, Sudan’s water us...
