This text book is designed to guide students from a basic knowledge of soil, water, plant, hydrologic and hydraulics to the state-of-the-art of irrigation system design, planning and management. The book will be helpful to the students of Agriculture, Agricultural and Civil Engineering and other related fields. The book is written in simple and lucid languages which will make the students interesting in reading the book and understanding the concept of farm irrigation very effectively. The book is written covering the entire syllabus of Irrigation Engineering which is taught in various State Agricultural Universities and is written as per the recommended syllabus of fifth Deans Committee meeting of Indian Council of Agricultural Research (ICAR), New Delhi. The book will not only be helpful to the students at under-graduate and post-graduate level, but also will be a helping tool for all practicing irrigation engineers, agriculturists, design engineers, researchers, extension personnel and all others who are directly or indirectly associated with irrigation science and engineering. The book contains 78 solved problems, 542 short and long questions, 65 tables, 135 figures and 136 references which will be of immense help to the students and design engineers. Several field experimental result are also presented at appropriate sections in various chapters in this book which will attract the attention of the students in the subject matter. In addition, the book contains a number of multiple type questions with answers. These multiple type questions are prepared covering all the chapters of irrigation engineering. These questions will help the students who prepare for various competitive examinations including GATE, NET, ARS, JRF and SRF examinations of ICAR.
