Water resources stored by dams and reservoirs play an essential role in water resource management, hydropower and flood control. Where there is an extensive network of dam infrastructures, dams have made a major contribution to economic and social development, providing considerable storage capacity per capita. However, dams and reservoirs may also have an important social and environmental impact, and should be studied within the framework of integrated water resource management and sustainable development. Dams and Reservoirs, Societies and Environment in the 21st Century presents the latest research on the role played by dams and reservoirs in 21st century societies, in developed, emergent and developing countries. It analyses the viability of dams and suggests alternative solutions from a holistic perspective, considering the technical, economic, social and environmental aspects. Other issues covered include the social acceptability of dams, public involvement and dam awareness. The book covers subjects ranging from dam engineering, through the benefits and drawbacks of dams, to their social and environmental impact, and contains numerous case studies of the constructive contributions that reservoirs have made to water development and management. The book is a valuable resource for professional and dam engineers, water managers, governmental organizations and commercial enterprises responsible for dam development and management.

This book provides an introduction to the scientific fundamentals of groundwater and geothermal systems. In a simple and didactic manner the different water and energy problems existing in deformable porous rocks are explained as well as the corresponding theories and the mathematical and numerical tools that lead to modeling and solving them. This approach provides the reader with a thorough understanding of the basic physical laws of thermoporoelastic rocks, the partial differential equations representing these laws and the principal numerical methods, which allow finding approximate solutions of the corresponding mathematical models. The book also presents the form in which specific useful models can be generated and solved. The text is introductory in the sense that it explains basic themes of the systems mentioned in three areas: engineering, physics and mathematics. All the laws and equations introduced in this book are formulated carefully based on fundamental physical principles. This way, the reader will understand the key importance of mathematics applied to all the subjects. Simple models are emphasized and solved with numerous examples. For more sophisticated and advanced models the numerical techniques are described and developed carefully. This book will serve as a synoptic compendium of the fundamentals of fluid, solute and heat transport, applicable to all types of subsurface systems, ranging from shallow aquifers down to deep geothermal reservoirs. The book will prove to be a useful textbook to senior undergraduate and graduate students, postgraduates, professional geologists and geophysicists, engineers, mathematicians and others working in the vital areas of groundwater and geothermal resources.

Written as a companion to the bestseller, Restoration Agriculture, this book will help farmers capture water in areas they want to, and avoid having water flow immediately to the low point. The result? Less water expense, healthier crops and livestock, and less erosion ... just to name a few. What you will read in this book is a distillation of over 25 years of on-the-ground experience working with and modifying the Yeomans' Keyline Plan. From the back yard suburbs to 10,000-acre ranches and everywhere in between, from permafrost mountainsides just shy of the Arctic Circle, to equatorial boulder fields of East Africa, areas with 300 inches of rain per year to those with less than 3 inches, I have personally installed systems based on the Keyline design methodology and its modified forms.What you will read in this book is tried and true. It is intended to give a sufficient background to any landowner so that they can optimize their water resource for higher site productivity, have greater drought resistance and just as importantly, to know deep in their heart that they have made even one little piece of earth a little more life-filled, livable and green.

Water is critical to all human activities, but access to this crucial resource is increasingly limited by competition and the effects of climate change. In agriculture, water management is key to ensuring good and sustained crop yields, maintaining soil health, and safeguarding the long-term viability of the land. Water management is especially challenging on smallholder farms in resource-poor areas, which tend to be primarily rainfed and thus highly dependent on unreliable rainfall patterns. Sustainable practices can help farmers promote the development of soils, plants and field surfaces to allow maximum retention of water between rains, and encourage the efficient use of each drop of water applied as irrigation. Especially useful for farmers' groups, agricultural extension workers, NGOs, students and researchers working with farmers in dryland areas, this comprehensive yet concise book is a practical and accessible resource for anyone interested in sustainable water management.

This book highlights the underlying principles and outlines some of the key hi-tech practices and technology interventions required to achieve enhanced productivity. It discusses horticulture technology interventions like varietal improvement including genetically modified crops; good agricultural practices like optimum planting density, micro-irrigation, fertigation, integrated nutrient management, plant bioregulators, precision horticulture, protected cultivation, nanotechnology, and integrated farming systems; integrated management of insects, mites, disease pathogens, nematodes, and weeds; and post-harvest management practices like handling, storage and processing to reduce crop losses. The importance of attaining food and nutritional security through hi-tech horticulture and profitable marketing of horticultural produce is also discussed. This book will be of immense value to the scientific community involved in teaching, research and extension activities related to hi-tech horticulture strategies for enhancing productivity in enhancing farmers’ income, food, nutrition and livelihood security. The material can be used for teaching postgraduate courses. The book can also serve as a very useful reference to policymakers and practicing farmers.
