GEOLOGY

Detailed explanation-1: -Permeable material contains interconnected cracks or spaces that are both numerous enough and large enough to allow water to move freely. In some permeable materials groundwater may move several metres in a day; in other places, it moves only a few centimeters in a century.

Detailed explanation-2: -(pɜrmiəbəl ) adjective. If a substance is permeable, something such as water or gas can pass through it or soak into it.

Detailed explanation-3: -Moisture permeability is the material’s resistance to the water vapor diffusion through a unit of surface area. This can be experimentally determined using one of two methods, as described in ASTM standard E96M-15 [34]. The two methods are the desiccant method and the water method.

Detailed explanation-4: -The permeability rate is a measure of how fast applied irrigation water moves through the soil. If an irrigator applies water at a rate exceeding the ability of the soil to accept it, the water will pool on the surface and eventually will run off, causing a non-uniform irrigation application and soil erosion.

Detailed explanation-5: -Permeable Surfaces or Materials Permeable surfaces contain pores or openings that allow liquids and gases to pass through. These surfaces can be penetrated. Some common permeable surfaces are gravel, porous materials and grass.
