Estimation of seepage losses from cracked rigid canal liners using finite element modeling
This study numerically investigates the effect of cracks in rigid canal liners on seepage control. Firstly, the case of a single crack is analyzed for different locations and widths then, the case of multiple cracks is examined. The results show that a single crack in a rigid canal liner increases the seepage losses by 2.3–4.6 times its value in an un-cracked liner, just under the canal’s bed, depending on the crack’s location, with the maximum value occurring when the crack is at the bed’s centerline. The crack’s location has a negligible effect on the deeper soil. The amount of seepage from the lined canal is directly proportional to the crack’s width. Multiple cracks drastically reduce the liner’s efficiency, where cracks with total widths of 3, 4, 5, and 6% of the canal bed width cause losses approaching 65.57%, 76.80%, 86.67%, and 87.79% of those from the unlined canal.
