Civil EngineeringQP$2259.$ Permeability is a critical property in the design and performance assessment of landfill liners, as it determines the rate at which fluids can pass through the composite material. Landfill

liners are typically composed of multiple layers of different materials, each with its own permeability and thickness. These layers work together to minimize the leakage of hazardous

substances into the surrounding environment, protecting soil and groundwater from contamination.

Consider a composite material used in a landfill liner composed of following distinct layers, each with specific thickness and permeability properties. The properties of the layers are

summarized in the following table:

this calculation because it accounts for the varying contributions of each layer based on its thickness, providing a more accurate representation of the overall permeability.
