Abstract

Canals require regular maintenance and repairs during their operational life span. Repairs require the identification of problem and strategic devising of solution. When there is some construction flaw like selection of wrong materials or non-compliance with the technical specifications, the canal can not perform as per design and manifests serious problems during operation. In Sardar Sarovar Project, the command area is 1.8 million hectare and the canal network is very long, approximately 76000 Kilometer, and hence some issues related to defects in the construction had been encountered during the operation. Two case studies discussed here shed light on what kind of defects were found and how the solutions were worked out using geosynthetics in a very innovative way. Prima facie irreparable looking canals were restored in a very short period with cost effective, still permanent solutions which prove that geosythetics can effectively address the constriction defects in some cases and in some cases help restore already failed canals.
