Summary This textbook is a comprehensive volume on sprinklers and drip irrigation and covers all the basic and fundamentals concepts related to these topics. It is the first book to consider relative-flow-ratio as an evaluation criterion for both sprinkler and drip irrigation designs. It also discusses various types of sprinklers (used for irrigation), their complex layouts, design methodologies, selection criteria explained with practical examples, and their operations and maintenance under different conditions. In addition to operation and maintenance of drip irrigation components, the book also explains the drip irrigation hydraulics and various design aspects and the effect of the same on their performance. It also has one important chapter on Rhizosphere modelling which introduces the state-of-the-art technologies in optimal irrigation and fertigation scheduling. Worked out examples and solved problems in the chapters would aid to learning and understanding of the topic among the students. Given the contents, the book will be extremely useful for the undergraduate and postgraduate students of agriculture engineering, irrigation engineering and civil engineering. This textbook will also be useful for researchers, engineers and professionals working in these areas.
