Under-Drainage Arrangements in Canals
Introduction:
Canals are constructed to transport water from one place to another for irrigation, industrial use, or other purposes. It is essential to design an efficient drainage system to maintain the structural stability of the canal. Under-drainage arrangements are necessary to ensure the proper functioning of the canal.
Lined Canals:
Lined canals are constructed with a lining material such as concrete, asphalt, or clay to prevent seepage of water from the canal. However, under-drainage arrangements are still required in lined canals to remove the seepage water that penetrates through the lining material. The under-drainage system consists of perforated pipes laid beneath the canal bed, which collects the seepage water and discharges it into a sump or a nearby water body.
Unlined Canals:
Unlined canals are constructed without any lining material, and the water flows through the soil. Under-drainage arrangements are necessary in unlined canals to reduce the seepage losses. The under-drainage system in unlined canals is similar to that of lined canals.
Conclusion:
Under-drainage arrangements are necessary in both lined and unlined canals to maintain the stability of the canal and reduce the seepage losses. Proper design and construction of the under-drainage system are essential for the efficient functioning of the canal.

Under-drainage arrangements are required in both unlined and lined canals. This is because water can seep through the sides and bottom of a canal, regardless of whether it is lined or not. The purpose of under-drainage is to collect and safely dispose of this seepage water, preventing water-logging of nearby land and possible damage to the canal structure itself. So, it is a necessary requirement for all types of canals.
