This book was released on 2007 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this paper is to facilitate the planning and design of land drainage systems for sound land and water management for engineers and other professionals. It considers the integration of technical, socio-economic and environmental factors and the need for system users' participation in the planning, design, operation and maintenance processes. The text provides guidelines for the appropriate identification of drainage problems, for the planning and design of field drainage systems (surface and subsurface) and the main drainage and disposal systems. The annexes provide more detailed information with technical background, appropriate equations, some cross-references for finding appropriate methodologies, and computer programs for calculation of extreme values, of permeability and some land drainage system parameters. --Publisher's description.

Download or read book Sustainable Irrigation and Drainage V written by C.A. Brebbia and published by WIT Press. This book was released on 2014-09-16 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation, as the biggest water user in most regions of the world is facing significant challenges in balancing social, economic and environmental needs for water. These proceedings of the 5th International Conference on Sustainable Irrigation and Drainage: Management, Technologies and Policies provide examples of how irrigation and drainage can become more sustainable, while acknowledging that the concept of sustainability is a goal that continues to change as our knowledge of the biophysical realities alters. In that sense moving towards sustainability is an ever evolving journey. A focus is made on the implications for improving sustainability, whether this is drainage, irrigation technologies, economic modelling, governance studies for irrigation management, reuse of water or any other aspect. Topics covered include: Irrigation management; Irrigation modelling; Irrigation systems and planning; Economic incentives; Groundwater issues; Water contamination and remediation; Drainage systems; Drainage modelling; International issues; Water reuse; Climate change effects; Water trade; Economics of irrigation; Socio-economic benefits.

Book excerpt: Modern Land Drainage 2nd edition is a fully revised and updated edition of the 2004 edition. Modern Land Drainage describes traditional drainage formulas (Hooghoudt, Kirkham, Donnan, Ernst, Glover-Dumm) for rainfed agriculture in the humid temperature zone. Significant parts are devoted to drainage for salinity control of irrigated land in (semi-) arid zones, and to drainage of rice land in the humid tropics. Institutional, management and maintenance aspects are extensively covered, as well as the mitigation of adverse impacts of drainage interventions on the environment. The latest computer applications for drainage design in the context of integrated water management are described (DRAINMOD, HEC, SWAP, etc.). Field surveys are executed by governments, with the aid of consultants, but rarely are the end stakeholders (i.e., farmers and general public) involved from inception to planning to execution of a drainage system. Yet, during the Operation, Management and Maintenance (OMM) phase of a water management system, they are expected to takeover, run, bear and be responsible for the costs of OMM. The book describes successful methodologies and processes to be followed for engagement of stakeholders at all levels, from government to farm, from minister to farmer, and, from beginning to end. The book covers all aspects needed for sustainable drainage. The latest survey methodologies with satellites and drones are suggested to assess cause and effect. Waterlogging and salinity are the effect of something caused most likely upstream of the drainage problem location. Hence treating the cause may be more cost-effective. Triple Bottom Line (social, environmental and financial considerations) and the water-food-energy nexus are an integral part of the drainage design process. Controlled drainage, i.e. the balance of removal and conservation of drainage water and minimising solute transport as low as reasonably achievable (ALARA principle) is extensively described. This work is intended for use both as a university level textbook and as a professional handbook; it is of particular value to professionals engaged in drainage development in the context of integrated water resources and river basin management, civil and agricultural engineers, government officials, university students and libraries.
