In the hydraulic design of canals, one of the most important decisions is the selection of the flexible coating <\/strong>that will ensure the stability and durability<\/strong> of the structure against the flow of water. Among the available options, the flexible coatings<\/strong> (such as waterproof textiles, erosion control blankets, confined rockfill, textile formwork filled with fine aggregate concrete) stand out for their adaptability and cost-effectiveness. But how do you know which one is right for your project? The key is in the shear stress<\/strong>.<\/strong><\/p>\n

\u00a0What is shear stress in a channel?<\/h2>\n

The shear stress (\u03c4) is the force per unit area exerted by the flow of water on the channel bed and slopes. This parameter indicates the flow drag capacity<\/strong> and helps us to know if the coating will be able to resist without erosion.<\/p>\n

It is generally calculated with the following simplified formula for uniform flow:<\/p>\n

\"F\u00f3rmula<\/p>\n

Why use flexible coatings?<\/h2>\n

Flexible coatings<\/a> for canals are better adapted to land deformations, require less land preparation, allow some degree of infiltration and some allow the establishment of vegetation, which is desirable in some cases.<\/p>\n
