Book Description
This report presents a methodology for identifying the main features (constraints and opportunities) of gravity-fed irrigation systems, which influence management and operation of the system for the purpose of water delivery. It presents the development of a generic for improving irrigation system operations. A case study of 64 irrigation systems in Sri Lanka is presented illustrating the practical application of the proposed typology.

Book Description
The book presents documentary evidence of the insufficiency of rehabilitation works to close the gap between the irrigation service and actual area irrigated of publicly funded national irrigation systems in the Philippines. It outlines a methodology for formulating a modernisation plan for national irrigation systems with focus on the mostly ungauged, medium to small canal irrigation systems. The proposed methodology adaptively modified some known modernisation concepts and techniques and integrated them in a more holistic framework in the context of changing weather patterns and river flow regimes. It includes in-depth review of rehabilitation works; system diagnosis; revalidation of design assumptions on percolation and water supply; characterisation of system management, irrigation service and demand; and drawing up of options and a vision for the modernised irrigation systems. Central to the proposed modernisation strategy is the logical coherence among the design of physical structures, system operation and water supply so that improvements of irrigation service are possible. The book discusses the development of the proposed methodology and demonstrates its utility in two case study irrigation systems.

Book Description
It is a comprehensive treatise on Water Resources Development and Irrigation Management. For the last 30 years the book has enjoyed the status of an definitive textbook on the subject. It has now been thoroughly revised and updated, and thus substantially enlarged. In addition to the wholesale revision of the existing chapters, three new chapters have been added to the book, namely, Lift Irrigation Systems and their Design, Water Requirement of Crops and Irrigation Management, and Economic Evaluation of Irrigation Projects and Water Pricing Policy.

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)]

Book Description
This report deals with some experiences of a set of irrigation systems situated in the Republic of Niger, along both banks of the Niger River. All these systems draw water from the river through low-lift, electrically powered pumping stations, which have been installed by the Government of Niger over the past 30 years. Irrigation of this kind is not a tradition in Niger. The introduction of this technology caused considerable changes in the way of life of local communities.

Book Description
Examines the extent to which the Government of Indonesia's aspirations were realized through turnover program adopted in 1987. The impacts of management turnover on irrigation management and irrigated agriculture in selected systems in West and Central Java are analyzed. This study is part of a comparative research program to examine the impacts of irrigation management transfer in several countries using a common methodology.

Book Description
An overview of an experiment in which 8 different methods of estimating actual evaporation and transpiration were compared using a common database. Methods based on field data, hydrological models, and satellite data were used and the objectives were to compare results and to assess the utility of each method for various applications.

Book Description
Public domain datasets are freely available on the Internet are easy to obtain, and often more up-to-date than those from local sources. This simplifies the modeling process and increases the ability to model basins anywhere in the world, from anywhere with Internet access. Although not all types of data are available, and some conversions may be needed, the information provided does allow for quick and easy simulations of basins. The Semi-Distributed Land-Use Runoff Process (SLURP) hydrological model has been designed to take advantage of such data sources. The application described in this report uses public domain data for topography, land use, seasonal variation in leaf area index (for transpiration) and climate data- all without calibration of parameters.
