Hydropolitics, Interest Groups and Governance
by Richard MeissnerThis book investigates the role that interest groups have played over the years in influencing the government of Namibia, the World Bank, the European Union and project implementation authorities to not construct the proposed Epupa Hydroelectric Power Station on the Kunene River in the Baynes mountains, a region on the border between Namibia and Angola. Some of the issues brought forward by the interest groups are the socio-economic impact the dam would have on the OvaHimba, as well as negative consequences for the river's aquatic and terrestrial environment. This book argues that interest groups and individuals have the ability to influence the above-mentioned institutions, and to such an extent that water politics and governance are not exclusively the domain of state institutions. As such, it argues that communal interest groups, living in remote parts of the world, can influence state institutions at various political scales.

Hydroponics and Environmental Bioremediation: Wastewater Treatment (Springer Water)
by Nitish KumarBioremediation is the use of biological interventions for mitigation of the noxious effects caused by pollutants in the environment including wastewater. It is very useful approach for a variety of applications in the area of environmental protection. It has become an attractive alternative to the conventional clean-up technologies that employ plants and their associated microorganisms to remove, contain, or render harmless environmental contaminants.Hydroponic systems, which utilize plants which are grown in a nutrient solution without soil, are expanding and raising great interest in the commercial and scientific community. They are engineered systems designed and constructed to utilize the natural processes involving macrophytes, media, and the associated microbial assemblages to assist in treating wastewaters. This is a relatively new approach in wastewater treatment by which a variety of emergent macrophytes are grown hydroponically on top of floating platforms with their roots developing freely into the flowing wastewater. The roots provide a support medium for attached microbial growth which participates in the treatment process.

Hydropower Development in the Mekong Region: Political, Socio-economic and Environmental Perspectives (Earthscan Studies in Water Resource Management)
by Nathanial Matthews Kim GehebThe Mekong Basin is home to some 70 million people, for whom this great river is a source of livelihoods, the basis for their ecosystems and a foundation of their economies. But the Mekong is also currently undergoing enormous social, economic, and ecological change of which hydropower development is a significant driver. This book provides a basin-wide analysis of political, socio-economic and environmental perspectives of hydropower development in the Mekong Basin. It includes chapters from China, Thailand, Laos, Cambodia and Vietnam. Written by regional experts from some of the region's leading research institutions, the book provides an holistic analysis of the shifting socio-political contexts within which hydropower is framed, legitimised and executed. Drawing heavily on political ecologies and political economics to examine the economic, social, political and ecological drivers of hydropower, the book's basin wide approach illuminates how hydropower development, and its benefits and impacts, are linked multilaterally across the basin. The research in the book is derived from empirical research conducted from 2012-2013 as part of the CGIAR Challenge Program on Water and Food's Mekong programme.

Hydropower Screws: Calculation and Optimal Design of Archimedean Screws
by Dirk Michael NuernbergkWater screw conveyors have been in use for centuries. Their invention is attributed to Archimedes. However, the idea of using this Archimedean screw also as a hydropower screw to convert hydraulic energy into electrical energy did not emerge until the 1990s. More recently, hydropower screws have been used very frequently at hydropower sites and have now also attracted increasing interest from scientists and users worldwide. This is due to the machine's very good efficiency, it's simple and inexpensive design, and its fish compatibility. This book provides calculation fundamentals for hydropower screws. The author focuses on the description of the hydraulic processes and gives a design flow that can be used to design hydropower screws. The hydraulic behavior, dimensions, speed, efficiency, forces acting on the screw such as sag or lift, as well as the arrangement of the gearbox and the choice of generator are discussed. The theoretical equations, some of which are newly derived, are applied using examples. Finally, a design flow is given that can be used to easily adapt an optimally designed hydropower screw to a location. New findings presented in various scientific publications have been incorporated into the translation of the second German edition. In addition, experiments were carried out at different locations, which led to a better understanding of the available data basis. This has allowed the theoretical predictions of this book to be confirmed experimentally. In addition, the author has investigated a number of faulty installations and has been involved in the design of successful working waterpower plants equipped with hydropower screws.

Hydropower in the New Millennium: Proceedings of the 4th International Conference Hydropower, Bergen, Norway, 20-22 June 2001
by Bjørn Honningsvåg Grethe Holm Midttømme Kjell Repp Kjetil Arne Vaskinn Trond WesterenThe power sector has undergone a liberalization process both in industrialized and developing countries, involving market regimes, as well as ownership structure. These processes have called for new and innovative concepts, affecting both the operation of existing hydropower plants and transmission facilities, as well as the development and implementation of new projects. At the same time a sharper focus is being placed on environmental considerations. In this context it is important to emphasize the obvious benefits of hydropower as a clean, renewable and sustainable energy source. It is however also relevant to focus on the impact on the local environment during the planning and operation of hydropower plants. New knowledge and methods have been developed that make it possible to mitigate the local undesirable effects of such projects. Development and operation of modern power systems require sophisticated technology. Continuous research and development in this field is therefore crucial to maintaining hydropower as a competitive and environmentally well-accepted form of power generation.

Hydrostructural Pedology
by Amjad T. Assi Rabi H. Mohtar Erik BraudeauWe first define the scientific problems of soil science to show that it cannot progress without a physical and systemic approach to the internal organization of the soil and its functionality with water. We show how the systems approach presented and described by Le Moigne (1994) should be reversed and modified in its application to soil science, descriptive science of the organization of the soil, to allow the development of a physical interaction between water and soil structure. This led us to particularly the exact formulation of thermodynamic state equations of the pedostructure. Thus, is opened the possibility of physical coupling, interdisciplinary, between biological models of the living and the organized soil medium represented by the pedon, its horizons and its pedostructures.Links to spreadsheets for figures referenced in the book (for download) are available at http://wefnexus.tamu.edu/hydrostructural-pedology/.
