| Abstract | ||
| Iran has limited water resources that require preservation and reducing water loss from reservoirs, especially in arid and semi arid regions. There are a number of methods available for to control water loss from reservoirs and canals. Concrete linings in water reservoirs and ponds are durable, but their efficiency is limited. Geomembrane sheets are another method of controlling leakage from water reservoirs. In this research, high density polyethylene was used to lining a concrete water reservoir to test its suitability for water proofing and chemical resistance. The benefits and drawbacks of this new lining material were investigated in the design, execution and operation stages. Subsequently, the effectiveness of this liner to control water loss was tested under different. The results showed that a geomembrane liner over a concrete lining requires special consideration during design, installation and maintenance and accessories such as pipes and sumps to reduce excessive stress on the liner. The analysis of water leakage from the liner showed that proper design and installation of the liner and accessories reduce water loss about 38% and limit leakage to 16.9 mm/day/m2. | ||
