V. Ravikumar is currently the chief Scientist in an All India coordinated project namely Irrigation Water Management at Water Technology Centre, Tamil Nadu Agricultural University (TNAU), Coimbatore, India. He obtained Bachelor of Engineering degree from Agricultural Engineering College, TNAU, Coimbatore; and masters and doctorate degrees in Irrigation Water Management in College of Engineering, Guindy, Chennai. He has more than 30 research publications which include two in American Society of Civil Engineers, three in Agricultural Water Management and one in Irrigation Science. He has taught this subject of Sprinkler and Drip irrigation to students of agricultural engineering, working professionals and farmers for a period of 27 years. He is a Co-developer of a popular free software for the design of drip irrigation systems namely, Drip System Simulation Programme (DSSP). He was awarded with Shrimati Saroma Sanyal Memorial prize by Institution of Engineers (India) in 2011.
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.
