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’.
