Book excerpt: Sustainable water resources planning deals with the interface of water resources science and the needs of human populations. It highlights works that addresses practical methods and basic research in, for example: quantity and quality management of groundwater and surface water resources; sustainability of water resources and water availability; water use and reuse including managed aquifer recharge and storage; geopolitical and socio-economic aspects of water resource management; water development and human activity impacts on ecological systems and human health, including, for instance, agricultural and climatic impacts, subsurface waste storage and injection, geothermal energy development and subsurface energy storage. This book provides up-to-date systematic and scientific analyses of such water problems and suggests sustainable measures to overcome them through effective surface and sub-surface water resource management. It is immensely valuable to students, researchers, water resource managers, hydrologists and all those who are engaged or interested in any aspect of river water conservation and management of water resources.
