Irrigation is an age-old art–perhaps as old as civilization. Nevertheless, the increasing need for crop production due to the growing population and climate change in the world is necessitating a rapid expansion of irrigated agriculture throughout the world. Surface irrigation is the oldest and still the most widely used method of water application to agricultural lands. But, one of the major concerns is the generally poor efficiency with which water resources have been used. Water is limited resource and also very expensive to transport. Thus, the use of the limited water that is available wisely with a minimum loss and maximum water use efficiency is very crucial.
