Use of Geomembranes in Bureau of Reclamation Canals, Reservoirs, and Dam Rehabilitation, December 1995
The report summarizes Bureau of Reclamation experiences with geomembranes for seepage control in canals, reservoirs, and dams. This report also presents design criteria, construction procedures, and O&M considerations for buried geomembrane canal linings. Results indicate that buried geomembranes are generally providing satisfactory service for seepage control, and that they are viable alternatives in areas not suitable for concrete or compacted earth linings. Some problems have been encountered with slope stability of the protective soil cover on steeper slopes, and additional studies are needed concerning the stability problem. Laboratory studies and field observations indicate that some stiffening of PVC geomembrane has resulted in a reduction in elongation, an increase in tensile strength, and a decrease in resistance to damage at low temperatures.
