The channels made of burnt clay tiles of different geometric shape and capacity have been tested in field irrigation channels of DTW and STW commands of the New-Alluvial Agro-Climatic Zone of West Bengal. The half round tiles were of 55 cm in length and 30, 31 and 33 cm in diameters. The rectangular shape designed (plane surfaces) and roof tiles were 40 cm x 25 cm x 2.2 cm and 45 cm x 22 cm x 1.75 cm, respectively. The average seepage losses and roughness coefficients (Manning’s 'n') were 12.613 cm³/cm²/ day and 0.025,9.11 cm³/cm²/day and 0.052 and 10.24 cm³/cm²/day and 0.052 for half round, designed and roof tile channels, respectively. The cost of construction including necessary earthwork and supprting structures of the channels of x-section areas about 350-475 cm² 730-815 cm² and 675 cm² for half round, roof and designed tiles were Rs.70, 85 and 90 per metre length, respectively. The costs for the comparable sizes brick lined channels were estimated to Rs.200. 365 and 355 per metre length. The tile channels reduced the cost of construction 65, 76.71 and 74.64% and the seepage losses 90.35, 92.16 and 93.03%, respectively.
