Detailed explanation-1: -Permeability is a property of porous materials that is an indication of the ability for fluids (gas or liquid) to flow through them. Fluids can more easily flow through a material with high permeability than one with low permeability.

Detailed explanation-2: -The permeability of a porous medium is a measure of the ease with which a fluid will flow through the medium; the higher the permeability, the higher the flow rate for a given hydraulic gradient. The permeability is a statistical average of the fluid conductivities of all the flow channels in the solid body.

Detailed explanation-3: -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-4: -Permeability is defined as the volume of a fluid of unit viscosity passing through a unit cross section of the medium in unit time under the action of a unit pressure gradient.

Detailed explanation-5: -Porosity: is a measure of the void spaces in a material. Permeability: a measure of the ability of a material (such as rocks) to transmit fluids. Porosity and permeability are related properties of any rock or loose sediment. Both are related to the number, size, and connections of openings in the rock.
