The water thus saved can be utilised for the extension and improvementof irrigation. Lining of water courses in the areas irrigated by tubewells assumes special significance as thepumped water supply is relatively more costly. The reduced seepage also prevents rise of the sub-soil watertable and thus reduces the possibility of damage to the adjoining areas by water logging.

5 Further, due toadoption of highervelocitiesin a Lined canal there is a saving in the cross-sectional area of the canal and landwidth required, withcorrespondingsaving in the cost of excavation and masonry works. It helps inretentionof shape of the canal. Lining also results inimprovementofcommandand larger working head standard deals with Design of Lined Canals . However, before lining of a canal is decided,techno-economicjustificationfor the same should be established. Selection of a particular type of lining should be arrived atbased on materials available and overall costvis-a-vissaving in seepage and forvarious types of lining shall becollectedand consulted before deciding on aparticulartype of generalguidelineswith regard to factors influencing the selection of the type of lining are given in thisstandard, for the assistance of the designer.

6 But each project should be individually analysed taking intoconsiderationits peculiar standard was first published in 1982. The first revision has been taken up in the light of thecommentsreceived from the Irrigationdepartmentsof various states. In this revision functions of lining and various typesof lining have been included. Changes in side slopes, free board, etc, have also been is no ISO standard on the subject. This standard has been prepared based on indigenousmanufacturers'data/practicesin the field in the purpose of deciding whether a particularrequirementof this standard is complied with, the final value,observed or calculated,expressingthe result of a test or analysis, shall be rounded off in accordance withIS2:1960'Rulesfor rounding off numerical values(revised)'.
