This book discusses the development of useful models and their applications in soil and water engineering. It covers various modeling methods, including groundwater recharge estimation, rainfall-runoff modeling using artificial neural networks, development and application of a water balance model and a HYDRUS-2D model for cropped fields, a multi-model approach for stream flow simulation, multi-criteria analysis for construction of groundwater structures in hard rock terrains, hydrologic modeling of watersheds using remote sensing, and GIS and AGNPS.
Modeling aspects have added a new dimension in research innovations in all branches of engineering. In the field of soil and water engineering, they are increasingly used for planning, development, and management of land and water resources, including analysis of quantity and quality parameters of surface and ground water, flood forecasting and control measures, optimum allocation and utilization of irrigation water. The application of these models saves considerable time in decision support systems and helps in conservation and optimum allocations of scarce precious natural resources.

The depletion of land resources is one of the greatest challenges for mankind in this millennium. Shrinking land resources, weather aberrations, deterioration of land quality, and the globalization and liberalization of market economies have become intertwined to influence the sustainable management of land resources and land use plans. This important volume, Sustainable Management of Land Resources: An Indian Perspective, addresses these challenges. This comprehensive volume, covering important research, much of it gathered with the use of new technology, tools, and applications, is organized into four sections: (add bullets) land resource inventory and characterization geospatial technologies in land resource mapping and management soil nutrient status and management land use planning and livelihood security The volume looks at how scientists translate their knowledge and experience in sustainable land resources and management into implementable policy decisions, with a particular focus on India. Since India is an agrarian economy, the land resources assume a very critical role affecting the livelihood of a vast majority of populace in the country. The information gathered—and the methods by which it is gathered—is applicable globally. This comprehensive publication will be highly useful for the researchers, academicians, extension workers, policymakers, planners, officials of land resources survey, planning and management institutions/agencies/departments, and others.
In past decades, urban water management practices focused on optimizing the design and operation of water distribution networks, wastewater collection systems, and water and wastewater treatment plants. However, municipalities are now faced with aging urban water infrastructures whose operation must be improved and expanded to maintain current high standards of living as well as new challenges such as climate change, systems sustainability and water quality issues. Integrating the latest developments in urban water hydrology and management, Urban Water Engineering and Management takes a system approach to urban water hydrology, engineering, planning and management, supplying examples and case studies and highlighting pressing issues such as urban water governance, disaster management, and climate change impacts on urban areas. The book draws attention to climate change as a main concern of this century by focusing on its impact the components of water cycle. The book covers modeling of urban water cycle components, urban water supply, and distribution systems demand forecasting. It also presents classical issues, such as design of water distribution networks and wastewater and storm collection in urban settings, from a system's perspective. The text also includes a discussion of water governance and disaster management in urban areas and the urbanization effects on the environment and the needed water infrastructure development in urban areas. Against this background, the authors discuss the importance of understanding the principles of simulation, optimization, multiple-criterion decision making, and conflict resolution for successful, integrated urban water management. They explore integrated water management and planning solutions for incorporating structural and nonstructural means to achieve the best operational schemes at affordable costs, going beyond using the existing structures and physical limitations on water availability to include technical, social, political, and economic aspects of better water and wastewater management in urban areas. Written and designed especially for intermediate and advanced courses/modules in water resources in civil and environmental engineering, and in urban planning, the book can be used as a textbook for civil engineering, urban and regional planning, geography, environmental science, and in courses dealing with urban water cycle. It also introduces new horizons for engineers as well as policy and decision makers who plan for future urban water and regional sustainability. Engineers and planners, especially those who work on design, planning, and management of urban systems and/or community development, can use this book in practice because it deals with a broad range of real world urban water problems.

After the 1998 flood of the Yangtze River, one of the world’s most important rivers, environmental experts realized that, to control flooding, much more attention must be paid to vegetation cover on bare lands, thin forest land, and shrub-covered land in mountain areas. In 1999, an environmental monitoring project of the forests in 11 provinces of the Yangtze River basin was undertaken. This book reports on soil loss prediction and the successful practices of soil loss control in eastern China in recent years.
