| Abstract: | The permeability of three types of impervious canals is measured with ponding test method. The three types of canals are: ① composite material impervious canal; ② U-shape prefabricated concrete canal; ③ U-shape cast-in-site concrete canal. The measurement results of permeability for the three types of canals are 1.92, 7.13, and 1.68 L/(m 2·h) respectively, and are 95.5%, 71.7%, and 95.8% less than corresponding soil canals respectively. |
