Available in PDF, EPUB and Kindle. Book excerpt: The current book attempts to fill the gap in one of the major subject of land drainage that will have a major impact on production and productivity of irrigated lands. The book Titled `Drainage Engineering: Principles and Practices` deals with the subject of surface and subsurface drainage to reclaim waterlogged salt affected soils. Based on the course curricula as suggested by Deans´ committee constituted by ICAR, the current publication has been divided into 11 Chapters covering all the facets of land drainage as applied to agriculture. Each chapter covers one of the related issues beginning with general introduction to water logging, soil salinity and land drainage in Chapter 1.Surface drainage methods, an essential intervention in monsoon climatic regions and as supplement to the subsurface drainage are included in Chapter 2. Drainage investigations, a precursor to problem diagnosis and to assemble the drainage design parameters are included in Chapter 3. The drainage design procedures such as assessment of drainage depth, spacing and capacity of drains forms the subject matter of Chapter 4. While drainage materials are discussed in Chapter 5, drainage construction procedures and methodologies to monitor and evaluate completed projects are included in Chapter 6. Some of the new drainage techniques such as mole, interceptor, vertical and bio-drainage have been included in Chapter 7 since these can either be applied singly or in integration with horizontal subsurface drainage. Chapters 8-10 deal withreclamation of salt affected soils,acid soils and management of saline water. Eco-friendly reuse and disposal of saline drainage wateralso form the subject matter of discussion of Chapter 10. Cost calculations, socio-economic and environmental issues associated with drainage projects have been included in final chapter 11. Glossary of terms has been added for quick overview of the terms used in the book. Clearly, each and every aspect of surface and subsurface drainage for agricultural lands has been covered in the book.Besides covering the principles of land drainage, field practices have been included making the book a handy tool for specialized training programmes on land drainage. It is believed that the book will find its place in the shelves of students and teachers, field functionaries and libraries of state agricultural universitiesand civil engineering colleges.

Download or read book The Inter Relationship Between Irrigation Drainage and the Environment in the Aral Sea Basin written by M.G. Bos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The irrigated area in the Aral Sea basin totals about 7. 5 million hectare. Part of the water supplied to this area is consumed by the irrigated crop; the remainder of the supplied water drains to the groundwater basin, to downstream depressions, or back to the rivers. During its use, however, this drained part of the water accumulates salts and chemicals. The disposal of this polluted water causes a variety of (environmental) problems. If the percentage consumed water of the total water supply to an irrigated area (the so-called overall consumed ratio) can be increased, less water needs to be drained. This alleviates part of the related (environmental) problems. Further, if the overall consumed ratio for the above 7. 5 million hectare is improved, less water needs to be diverted from the rivers. Hence, more water can flow towards the Aral Sea. As mentioned above, part of the non-consumed irrigation water drains to the groundwater basin. Commonly, the natural discharge capacity of this basin is insufficient to handle this imported water. As a result, the groundwater table rises towards the land surface causing waterlogging. In (semi-)arid zones this waterlogging triggers a soil salinity problem resulting to a significant reduction in crop yields. The artificial increase of the discharge capacity, and lowering of the groundwater table, solves the soil salinity problem.

Download or read book Practical Drainage for Golf Sportsturf and Horticulture written by Keith McIntyre and published by John Wiley & Sons. This book was released on 2000-07-15 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical Drainage is easy to read and presented in a non-technical style generously supported with helpful illustrations. There are three key messages in this book: water moves sideways only slowly through soil--leading to a detailed description of how drains work; the how-and-why of perched water table methods of construction; and sands are different from one another--they must be tested before use in turf root zones. These key messages are preceded by detailed descriptions of how water moves into soils and the effects of compaction on that movement. The final chapters give step-by-step guidelines for calculating drain spacings and depths, based on measurements of the hydraulic conductivity of the soil and its various layers. There are also chapters about how to measure hydraulic conductivity and how to design and install sub-soil drainage systems.

Download or read book Management of Irrigation and Drainage Systems written by Hector M. Malano and published by CRC Press. This book was released on 2018-05-02 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides an overview of the principles required for a service orientation in the management of irrigation and drainage systems. The material covered is designed to emphasize an area largely neglected in the irrigation and drainage management literature. The dominating philosophy underlying this book is that irrigation and drainage systems must be managed as a service business responsive to the needs and changing requirements of its customers. It is postulated that this service approach to the management of irrigation and drainage systems consitutes a key element of the startegy that is needed to improve the current level of performance of many irrigation and drainage systems worldwide. Enhanced performance of irrigation is a prerequisite if we are to face the enormous challenge of producing greater quantities of food to meet the demand of a growing population. This is particularly the case in an environment with increasing competition for water from industry and urban water users, set against mounting concerns about environmental sustainability.
