The author documents the increasing competition for water resources in the Western U.S. and presents a history of automated irrigation systems. The text continues with a detailed description of the structure, function, and laboratory and field testing of several models of pneumatic valves for use in both underground pipelines and open ditches, including their durability, time to open and close, and the varying amounts of air pressure required to close them at various depths. The book concludes with recommendations for future research, particularly portable pneumatic checks and valves with fail-safe features. These innovations have the potential to revolutionize irrigation, saving farmers time, labor, and water, while increasing efficiency and reducing environmental impact. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Aggiungi al carrelloPaperback. Condizione: New. Print on Demand. This book investigates the constant-head-orifice farm turnout (CHO), a structure used to measure and control irrigation water that has been in use on U.S. Bureau of Reclamation projects since the 1940s. The author explores the turnout's operating characteristics through a detailed study of four different geometries of the CHO, calibrated in both indoor and outdoor test channels, and operated under a variety of flow conditions. The effects of sediment, high canal velocities, varying downstream water levels, and plugging of the orifice gate by debris were studied. The author found that the CHO provided reasonably accurate measurement of discharge under most operating conditions, but when the gate opening was obstructed with debris or when the tail water level was increased, discharges were much less than indicated by the calibration curve. The author also includes design and calibration information for a steel constant-head orifice turnout, a lower-cost alternative to a reinforced concrete turnout that can be dismantled and moved from one place to another on a farm as irrigation development changes. This book is a valuable resource for water resource engineers, irrigation engineers, and anyone interested in the design and operation of irrigation water measurement and control structures. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

This book delves into the history of surface irrigation automation, tracing the development of innovative technologies that aimed to revolutionize agricultural practices. The author, a pioneer in the field, meticulously documents decades of experimentation and research, exploring the evolution of various irrigation systems and components. From the earliest attempts to adapt existing pneumatic valve closures to the development of automated check gates and sophisticated energy dissipation structures, this book presents a detailed account of the challenges and successes encountered in automating irrigation delivery. The book's narrative spans multiple regions and settings, showcasing the practical applications of these technologies in diverse agricultural environments. The reader is transported to arid regions of the American Southwest, to sugar plantations in Hawaii, and to mountain meadows, gaining insights into the unique challenges and opportunities each location presents. The thematic depth of this book extends beyond a mere chronicle of technical advancements. It examines the complex interplay of economic factors, environmental concerns, and the social dynamics of farming communities in shaping the adoption of irrigation automation. Ultimately, this book offers a valuable historical perspective on the pursuit of water efficiency and labor reduction in agriculture, highlighting the enduring challenges and potential benefits of automating surface irrigation systems. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
