The maximum flow rate a canal liner can handle depends on he type of liner material, the canal's design, and the environmental conditions.Flexible geomembrane liners can typically handle moderate to high flow rates, but their performance may be influenced by factors like liner thickness, the smoothness of the canal bed, and how well the liner is anchored.
Concrete liners can generally manage higher flow rates due to their strength and rigidity, but they may be susceptible to cracking under extreme pressure. Proper installation, including securing the edges and ensuring the liner is free of damage, is crucial to preventing issues with high flow rates.
