Book Description
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.

Category : Science
Languages : en
Pages : 158
Book Description
This report contains a collection of papers from a workshopâ€"Strengthening Science-Based Decision-Making for Sustainable Management of Scarce Water Resources for Agricultural Production, held in Tunisia. Participants, including scientists, decision makers, representatives of non-profit organizations, and a farmer, came from the United States and several countries in North Africa and the Middle East. The papers examined constraints to agricultural production as it relates to water scarcity; focusing on 1) the state of the science regarding water management for agricultural purposes in the Middle East and North Africa 2) how science can be applied to better manage existing water supplies to optimize the domestic production of food and fiber. The cross-cutting themes of the workshop were the elements or principles of science-based decision making, the role of the scientific community in ensuring that science is an integral part of the decision making process, and ways to improve communications between scientists and decision makers.

Role of Sediment in the Design and Management of Irrigation Canals

Publisher: CRC Press
ISBN: 9780415615792
Category : Technology & Engineering
Languages : en
Pages : 0
Book Description
The performance of irrigation schemes that carry sediment laden water is often poor. Modern irrigation schemes are increasingly demand based, which means that the water flow in the canals is determined by the crop water requirements. Accordingly the flow in the canal network is not constant as the crop water requirement changes with the climate and the growing stages. Also the inflow of the sediment is not constant throughout the irrigation season. Such schemes, particularly having unlined canals in alluvial soils, are difficult to design and to manage without compromising the flexibility or maintenance cost. This research has made an in-depth assessment on the role of sediment in the design and management of an irrigation scheme by using the data of Sunsari Morang Irrigation Scheme, Nepal. An analysis of the velocity and shear stress distribution across a non-wide trapezoidal canal has been made to derive the correction factor for the sediment transport predictors. An improved approach based on a rational concept of the design of canals for sediment transport is proposed. By using the sediment transport model SETRIC, a water delivery plan has been designed and tested for changing water and sediment inflow conditions that can be implemented with the existing canal infrastructure. The research also shows that flexibility of operation and efficient sediment management are difficult to achieve at the same time. A compromise has to be made and this needs to be reflected in the design. All methods to transport, exclude or extract the sediment are temporary measures and just transfer the problem from one place to the other. A better understanding of sediment movement helps to identify the problems beforehand and to find the best possible solutions.

On The Waterfront: Water Distribution, Technology And Agrarian Change In A South Indian Canal Irrigation System
Author: Peter P. Mollinga
Publisher: Orient Blackswan
ISBN: 9788125025078
Category :
Languages : en
Pages : 472
Book Description
Series: Wageningen University Water Resources Series. This book analyses the struggle over water in a large-scale irrigation system in Raichur District, Karnataka, South India. It looks at water control as a simultaneously technical, managerial and socio-political process. The triangle of accommodation of different categories of farmers, irrigation department officials and local politicians, involving water, votes, money, employment, credit and harassment, is documented. The book shows that the physical infrastructure, notably the division structures, are signposts of struggle, expressing the balance of power between farmers and the irrigation department, and that between head- and tail-end farmers. It concludes with a discussion of irrigation reform efforts in India: reasons for the very slow transformation of the sector, and how a more integrated perspective on irrigation could provide directions for the way forward.

Modernizing Irrigation Management
Author: Daniel Renault
Publisher: Food & Agriculture Org.
ISBN: 9789251057162
Category : Business & Economics
Languages : en
Pages : 240
Book Description
This publication describes the MASSCOTE methodology, illustrated by several applications in Asia. MASSCOTE is a comprehensive methodology for analysing the modernization of canal operation. The aim is to enable experts to work together with users in determining improved processes for cost-effective service-oriented management. It is based on previous tools and approaches widely used in Asia by FAO in its modernization training programme (rapid appraisal procedures and benchmarking). From diagnosis through the formulation of operational units and the planning of a service (based on the vision agreed upon with the users), MASSCOTE entails a systematic, ten-step, mapping exercise. The accompanying CD-ROMs contain the full document in English, excerpts in French, a draft version in Arabic and Chinese, training presentations and material, and a number of documents and references on irrigation system operation and management [System requirements: PC with Intel Pentium(r) processor and Microsoft(r)Windows 95/98/200/Me/NT/XP; 256 MB of RAM; 50 MB of available hard-disk space; SuperVGA monitor; 256 colours at 1024x768; Adobe Acrobat(r) Reader (not included on CD-ROM)]
