Rehabilitation and Modernization of Irrigation Projects is Often a Cover-up for Poor Quality Construction and Maintenance
Decreasing land and water resources available for irrigation projects is placing greater empasis on rehabilitation and modernization of irrigation projects. Inferior quality of the initial...
Development of an Underwater Canal Lining Method
The U.S. Bureau of Reclamation is developing a method of lining a large irrigation canal in-place while water flows in the canal, using an impermeable plastic membrane covered with concrete....
Economic factors of Drainage Water Reduction
Properly designed and maintained pressurized systems provide better irrigation control and greater infiltration uniformity. But irrigation costs are increased. Imposition of drainage water...
Location, Design, and Construction of Water Wells
Proper location, design, and construction of water wells are important to assure their efficient operation and minimize maintenance problems. Detailed and accurate records of the design...
