Download or read book Water Requirements for Irrigation and the Environment written by Marinus G. Bos and published by Springer Science & Business Media. This book was released on 2008-11-23 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped land. As such, irrigated agriculture is a productive user of resources; both in terms of yield per cropped area and in yield per volume of water consumed. Many irrigation projects, however, use (divert or withdraw) much more water than consumed by the crop. The non-consumed fraction of the water may cause a variety of undesirable effects ranging from water-logging and salinity within the irrigated area to downstram water pollution. This book discusses all components of the water balance of an irrigated area; evapotranspiration (Ch.2), effective precipitation (Ch.3) and capillary rise from the groundwater table (Ch.4). Chapter 5 then combines all components into a water management strategy that balances actual evapotranspiration (and thus crop yield) with the groundwater balance of the irrigated area (for a substainable environment). Chapter 6 presents CRIWAR 3.0, a simulation program that combines all water balance components into a single simulation procedure. The chapter describes the use of the CRIWAR software for developing water requirement tables and other useful information based on the selected water management strategy. This version greatly expands upon the capabilities of previously published programs.

Download or read book Charging for Irrigation Water written by C. J. Perry and published by IWMI. This book was released on 2001 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: nadequate funding for maintenance of irrigation works and emerging shortages of water are prevalent. The use of water charges to generate resources for maintenance and to reduce demand is widely advocated. Examples from other utilities, and from the domestic/industrial sectors of water supply suggest the approach could be effective. In developing countries, the facilities required for measured and controlled delivery of irrigation are rarely in place, and would require a massive investment in physical, legal and administrative infrastructure. To be effective in curtailing demand, the marginal price of water must be significant. The price levels required to cover operation and maintenance (O&M) costs are too low to have a substantial impact on demand, much less to actually bring supply and demand into balance. On the other hand, the prices required to control demand are unlikely to be within the politically feasible range. Furthermore, water supplied is a proper measure of service in domestic and industrial uses. But in irrigation, and especially as the water resource itself becomes constrained, water consumption is the appropriate unit for water accounting. This is exceptionally difficult to measure. An alternative approach to cope with shortage would focus on assigning volumes to specific uses–effectively rationing water where demand exceeds supply. This approach has a number of potential benefits including simplicity, transparency, and the potential to tailor allocations specifically to hydrological situations, particularly where salinity is a problem. Data from Iran are presented to support these contentions.

Download or read book Irrigation Handbook written by Natalie Ramsey and published by Murphy & Moore Publishing. This book was released on 2021-11-16 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The artificial techniques which are employed to apply controlled amounts of water with the objective of assisting agricultural activities fall under irrigation. The discipline finds a wide variety of applications such as maintenance of landscapes, revegetation of disturbed soils in dry areas, frost protection, suppression of weed growth, and prevention of soil consolidation. According to the method of water supply and the amount of water supplied, irrigation techniques can be classified into surface irrigation, micro irrigation, sprinkler irrigation and sub irrigation. Sprinkler irrigation can be further divided into methods using central pivot, lateral move, lawn sprinklers and hose-end sprinklers. Some of the different water sources which are used for irrigation systems are springs, wells, rivers, lakes, drainage water and treated wastewater. This book elucidates the concepts and innovative models around prospective developments with respect to irrigation. It aims to shed light on some of the unexplored aspects of irrigation. This book is appropriate for students seeking detailed information in this area as well as for experts.
Download or read book Irrigation Systems written by Adrian Laycock and published by CABI. This book was released on 2007-01-01 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all the confrontations man has engineered with nature, irrigation systems have had the most widespread and far-reaching impact on the natural environment. Over a quarter of a billion hectares of the planet are irrigated and entire countries depend on irrigation for their survival and existence. Considering the importance of irrigation schemes, it is unfortunate that until recently the technology and principles of design applied to their construction has hardly changed in 4,000 years. Modern thinking on irrigation engineering has benefited from a cross-fertilization of ideas from many other fields including social sciences, control theory, political economics and agriculture. However, these influences have been largely ignored by irrigation engineers.Drawing on almost 40 years of experience of irrigation in the developing world, Laycock introduces new ideas on the design of irrigation systems and combines important issues from the disciplines of social conflict, management, and political thinking.

Book excerpt: Prepared by the Task Committee on Recent Advances in Canal Automation of the Irrigation Delivery and Drainage Systems Committee of the Irrigation and Drainage Council of the Environmental and Water Resources Institute of ASCE Canal Automation for Irrigation Systems focuses on the technical aspects of modernizing irrigation systems through use of automated canal control systems. Canal automation has always offered an opportunity to save water and improve the efficiency of irrigation water supply projects or irrigation district operations. Recent technological and engineering advances now enable more accurate control of water deliveries throughout all parts of an irrigation project. Using information collected from irrigation systems around the world in conjunction with new advances in control theory research, this Manual of Practice examines how and when to implement canal automation within the context of canal modernization. Topics include: the modernization process, constraints, and concepts; survey of irrigation physical infrastructure; SCADA systems; control operation concepts; canal hydraulic properties; control methods; verification of controller performance; and implementation of control systems. MOP 131 is an essential reference for professionals in agricultural and irrigation engineering, as well as owners, managers, and operators of irrigation water delivery systems.
