home and garden landscapingWhy drainage is provided behind lining of canals?
Where a lined canal crosses areas subject to seasonal high ground water or where the soil is sufficiently water tight to prevent the free draining of the seepage or leakage from the canal, suitable under drainage should be provided to protect the lining.
Similarly, you may ask, what is the purpose of canal lining?
Canal lining is the process of reducing seepage loss of irrigation water by adding an impermeable layer to the edges of the trench. Seepage can result in losses of 30 to 50 percent of irrigation water from canals, so adding lining can make irrigation systems more efficient.
Just so, what is lining and its purpose?
Linings provide a neat inside finish and conceal interfacing, padding, the raw edges of seams, and other construction details. A lining reduces the wearing strain on clothing, extending the useful life of the lined garment.
The Bureau of Indian Standard code IS: 10430-1982 “Criteria for design of lined canals and guidelines for selection of type of lining” (Reaffirmed in 1991) may generally be used, in addition to special codes like IS: 9451-1985 “Guidelines for lining of canals in expansive soils (first revision)” (Reaffirmed in 1991),
