The major objective in the preparation of this book has been to meet the needs of college and university students who seek information concerning the basic aspects of irrigation principles and practices which are of vital importance to the public welfare in arid regions. These aspects of irrigation, sometimes referrred to as the agricultural phases, are of special interest to students of agronomy, agricultural engineering, and civil engineering. Although the needs of students have been given first consideration and irrigation principles have been stressed, considerable material describing modern methods and practices is also included. Water commissioners, irrigation company officers, superintendents of irrigation projects, water masters, ditch riders, county agricultural agents in the western states, and irrigation farmers are all interested in the dissemination of knowledge that will contribute to better irrigation practices and more efficient use of irrigation water.
