A ditch liner includes: a first corrugation having first and second angled sections, and a central section; and a second corrugation having first and second angled sections, and a central section. The first angled sections are adjacent to each other, the second angled sections are adjacent to each other, the central sections are adjacent to each other, a width of the first angled section of the first corrugation is different than a width of the first angled section of the second corrugation at a first location, a width of the second angled section of the first corrugation is different than a width of the second angled section of the second corrugation at a second location, and a width of the central section of the first corrugation is equal to a width of the central section of the second corrugation at a third location.

An approach to restoring and protecting a canal divider wall includes positioning a precast panel over the wall in the channel with an inner cavity of the precast panel; installing a titanium bolt through the precast panel and the wall in the channel; and pumping a polymer grout through a bore defined in the cap.

A canal liner and method for installing a canal liner. The canal liner has a bottom portion, a first hollow sidewall and a second hollow sidewall. One or more of the sidewalls can have one or more weep holes to allow liquid to at least partially fill one or more internal voids thereof. The sidewalls can be coupled to the bottom portion via one or more hinges such that the canal liner can be transported in a substantially flat, planar shape and folded on-site and placed into the canal.
