Irrigation engineering is a branch of civil engineering that is involved in controlling and harnessing the various natural sources of water. This branch investigates various aspects of agriculture and irrigation in detail to determine the future prospects of irrigation. Irrigation engineering analyzes the efficiency of different irrigation systems to monitor their benefits and drawbacks. The main responsibility of irrigation engineering is to design and plan cost-effective and efficient irrigation systems. There are various advantages as well as disadvantages of developing irrigation systems but the benefits are far more than its disadvantages. One of the primary responsibilities of irrigation engineers deals with the problems that may arise in the watershed or the agricultural fields. In addition, irrigation engineers also deal with aspects such as the study of problems related to water, soil, crop relationship, and the design and structure of dams, canals, and other hydraulic and irrigation structures. This book is compiled in such a manner, that it will provide in-depth knowledge about the theory and practice of irrigation engineering. With state-of-the-art inputs by acclaimed researchers in this field, it targets scholars and professionals.
