Evaluation of concrete and geomembrane lining options for a canal in Egypt

This technical note complements a published lining evaluation for a canal in Egypt. Concrete and geomembrane linings are compared regarding leakage control and cost. Published data on leakage with concrete and geomembrane linings are reviewed, and analyses show that the predicted leakage rate is significantly lower with a geomembrane lining than with a concrete lining. The findings presented herein on leakage control and cost are significantly different from the findings of the published lining evaluation.
