A porous material has spaces that allow water to seep through it.
When a material has spaces that allow water to seep through, it signifies the property of permeability, which depends on the size, shape, and connectivity of these spaces. Permeable materials, like sand and gravel, can transmit water quickly, while impermeable materials, like clay, do not allow water to flow easily. This property is crucial for groundwater systems and aquifer management.
