Excerpt from Irrigation Practice and Engineering, Vol. 3
Volumes II and III are essentially devoted to a presentation of the fundamental principles and problems of irrigation engineering. While the author has endeavored to meet specially the needs of teachers and students in technical schools, considerable descriptive information and cost data have been added for the purpose of making these volumes more valuable to the engineers engaged in the construction and operation of irrigation systems. For use as text-books in class-room work, some of the descriptive material and detailed information may be considered only briefly and more emphasis laid on the fundamental principles and on the problems of economic construction.
The preparation of these two volumes results in part from the development of a course in Irrigation engineering presented at the University of California. It is based on an acquaintance with a large number of irrigation systems, located in most of the States of the western part of the United States and in western Canada, obtained through many opportunities for examination of these projects and through connection with a number of them. The writer has not confined himself to his own experience and observations, but has discussed the principles of irrigation engineering presented in this work with a number of successful engineers, who have had much experience in the construction and operation of irrigation systems. He has also availed himself not only of contemporary literature pertaining to American Irrigation engineering, but has consulted a large collection of foreign publications, mostly from India, Egypt, Spain and France. While there is still considerable difference of opinion among engineers regarding some of the principles of design of irrigation works, it is believed that the opinions and principles presented are in accordance with correct theory and good practice as demonstrated by careful observation.
This treatise on irrigation engineering, as presented in Volumes II and III, is largely confined to canals and other works which pertain to the usual types of irrigation systems.
