Book Description
Excerpt from Drainage Engineering The purpose of writing the following pages has been to present a general treatise on the drainage of agricultural lands. An attempt has been made to outline the various questions that should be considered in taking up a drainage problem, and to put into brief but comprehensive form the principles involved in the design and construction of drainage works. The activities of the past few years intended to increase and improve agricultural areas through drainage, have greatly enlarged the application of engineering and scientific studies to this character of work. In addition to unwatering and re claiming natural swamp and overflow lands, of which there are many millions of acres, principally in the humid sections of the United States, large drainage problems have developed and are still developing in the arid regions, as a result of irriga tion. It has been estimated on irrigated lands generally that about one-fourth of the total area becomes unfit for profitable cultivation unless protected by drainage. As a branch of Engineering, drainage presents many interest ing and difficult problems. On account Of the many varied and uncertain factors relating to soil and ground water conditions, it is diffit to formulate general laws governing many features Of it. Each particular problem requires special study for economic and efficient results. The subject involves a study of the soil, hydrographic conditions, and also the location, design and construction of waterways for carrying away the excess supply. The effect of drainage upon the soil embraces questions of agriculture and soil physics. In every drainage enterprise economic questions are also involved. The principles and methods I have endeavored to outline have been slowly developed through many years - even centuries. It is impossible, in most cases, to determine to whom the credit for them belongs. I have attempted, where possible, to give appropriate references throughout the text. Acknowledgment also is made to all whose writings I have read, to engineers whose cooperation I have had in working out drainage problems, and to many friends who have kindly assisted me in the work.

Book Description
Modern Land Drainage 2nd edition is a fully revised and updated edition of the 2004 edition. Modern Land Drainage describes traditional drainage formulas (Hooghoudt, Kirkham, Donnan, Ernst, Glover-Dumm) for rainfed agriculture in the humid temperature zone. Significant parts are devoted to drainage for salinity control of irrigated land in (semi-) arid zones, and to drainage of rice land in the humid tropics. Institutional, management and maintenance aspects are extensively covered, as well as the mitigation of adverse impacts of drainage interventions on the environment. The latest computer applications for drainage design in the context of integrated water management are described (DRAINMOD, HEC, SWAP, etc.). Field surveys are executed by governments, with the aid of consultants, but rarely are the end stakeholders (i.e., farmers and general public) involved from inception to planning to execution of a drainage system. Yet, during the Operation, Management and Maintenance (OMM) phase of a water management system, they are expected to takeover, run, bear and be responsible for the costs of OMM. The book describes successful methodologies and processes to be followed for engagement of stakeholders at all levels, from government to farm, from minister to farmer, and, from beginning to end. The book covers all aspects needed for sustainable drainage. The latest survey methodologies with satellites and drones are suggested to assess cause and effect. Waterlogging and salinity are the effect of something caused most likely upstream of the drainage problem location. Hence treating the cause may be more cost-effective. Triple Bottom Line (social, environmental and financial considerations) and the water-food-energy nexus are an integral part of the drainage design process. Controlled drainage, i.e. the balance of removal and conservation of drainage water and minimising solute transport as low as reasonably achievable (ALARA principle) is extensively described. This work is intended for use both as a university level textbook and as a professional handbook; it is of particular value to professionals engaged in drainage development in the context of integrated water resources and river basin management, civil and agricultural engineers, government officials, university students and libraries.

Book Description
Excerpt from Farm Drainage in the United States: History, Status, and Prospects The most recent rapid developmental era for drainage reclamation drew to a close about 1965. Drainage is the most extensive soil and water manage ment activity in agriculture. Approximately 110 million acres of the land within farms are artificially drained in the United States. About 9 million acres, or 25 percent, of the irrigated cropland in the Western States are artificially drained. Drainage can also have adverse effects in some situations by reducing or degrading wetlands vital to wildlife and serving hydrologic functions such as flood flow regulation. Drainage activities can also affect the quality of water bodies receiving drainage water. Drainage investigations in usda began with the Reclamation Act of 1902. This act is best known as creating the Bureau of Reclamation in the Depart ment of the Interior. A drainage unit to service irrigation project planning was simultaneously authorized for usda. In 1962, Public Law 87-732, the Drainage Referral Act, was enacted which prohibited usda from assisting landowners in draining potholes and marshes in Minnesota and the Dakotas if wildlife would be materially harmed. Currently, usda technical and financial assistance is no longer provided as a matter of policy except in unique circumstances as part of a conservation system related to irrigation water control, or as an essential element of an environmental system of practices. Thus, for usda, this publication represents an end to the era of strong usda support and assistance for drainage development activities.

Book Description
Excerpt from Engineering for Land Drainage: A Manual for Laying Out and Constructing Drains for the Improvement of Agricultural Lands Land drainage in this country has had its principal growth during the last twenty years. Its practice reaches from the simple drainage of a garden costing only a few dollars to that of tracts containing thousands of acres, involving elaborate plans and the expenditure of large sums of money. It includes the drainage of all kinds of lands which require it, either for profit or for health, and hence embraces a wider range Of topics than, upon first thought, seems to be involved.

Excerpt from Handbook of Irrigation and Drainage Bulletin 373, The Irrigation of Lucerne. By Dr. S. Fortier (chief of Irriga tion Investigations, United States Department of Agriculture), is reprinted, especially because of the interest which has been shown in Western Australia in Lucerne growing, which makes it advisable that growers, present and prospective, shall be placed in possession of the latest practical information and advice regard ing the best. Methods of irrigated culture and the utilisation of water applied to agriculture. The reprinted work, with its numerous illustrations, will be found generally adaptable to the conditions ruling in many portions of this State. The whole question of irrigation must be viewed from the standpoint of yvill it pay 17 Some people, carried away with the possibilities of irrigation. Lose sight of the all-important financial end of the question, and make extensive investment in apparatus which is unnecessary or unsuited to the work to be done. Others, from ill-advised ideas of economy, endeavour to irrigate without properly laying out their land, and spend on labour alone many times the cost of a suitable scheme. To speak intelligently about irrigation we must know the cost and the value, not only of the undertaking as a whole, but of the individual parts thereof. These are subjects of primary importance. The actual cash outlay necessary for operation is often considered as the cost of irrigation, but allowance has to be made for interest or depreciation on the investment in the irrigation plant.

Book Description
This manual contains the engineering tools and concepts that have proven useful in planning, constructing, and maintaining drainage systems for successful long-term irrigation projects. The manual is not a textbook. Mathematical and experimental development of the engineering tools has generally not been included. Indeed, not even all the innovative ways to use the tools are included. The manual provides drainage engineers a ready reference and guide for making accurate estimates of drainage requirements. Design and construction criteria, if followed with reason, will result in reliable drainage systems for irrigated areas. All the methods and techniques covered in the manual have proven to be very satisfactory through observed field conditions on irrigated lands throughout the world. Some methods have a more elegant development and basis in science than others, but all have been designed to solve practical problems in the field.

Book Description
Excerpt from Irrigation Development and Public Water Policy This is a study of the economic and social considerations that are part and parcel of irrigation development and public water policy. No longer can an irrigation project be considered solely in terms of the engineering problems it raises. Indeed, its success depends equally upon economic feasibility and social use. Although the federal government has carried on organized activity in this field for more than fifty years, no comprehensive coverage of the problems in irrigation development has been attempted since 1927, when Ray P. Teele published his notable work on the economics of land reclamation. New concepts, new approaches and procedures, have been applied and ever more attention is being paid to the socioeconomic implications. Admittedly, the problems of irrigated agriculture and its place in public water policy are complicated and controversial; nevertheless, a full, up-to-date survey seems necessary to assess the accomplishments of the past twenty-five years.
