| dc.description | Up to this time, concrete structures had not been extensively in irrigated fields where severe freezing and thawing occurs. However, with the development of lightweight products for the distribution of irrigated waters, the economic feasibility and practicality of concrete was being reconsidered. The article discusses a conducted to study the use of concrete products for conveying irrigation water, three concrete producers became interested in placing some facilities at the Carrington Irrigation Branch Station and provided a grant to initiate this work in 1964. It was concluded that concrete pipe was more expensive to install than slip-formed concrete lining but was more effective in water control and perhaps as economical in the long run. A permanent concrete distribution ditch created problems in tillage at the head of a row crop field and this accounted for a major part of the annual cost of operation. A concrete lined ditch is better suited for conveying than for distributing water. | |
