Detailed explanation-1: -The term “permeability of soil” refers to the capacity of soil to allow the passage of liquids such as water. For buildings that will be in contact with water, this is a crucial consideration. A soil’s empty areas are linked together, allowing water to move through them.

Detailed explanation-2: -For groundwater to be able to get into a rock with good porosity it must also have good permeability. For a rock to be permeable and for water to move through it, the pore spaces between the grains in the rock must be connected. Permeability is therefore a measure of the ability of water to move through a rock.

Detailed explanation-3: -There are 3 types of permeability: effective, absolute, and relative permeabilities.

Detailed explanation-4: -Clay is the most porous sediment but is the least permeable. Clay usually acts as an aquitard, impeding the flow of water. Gravel and sand are both porous and permeable, making them good aquifer materials. Gravel has the highest permeability.

Detailed explanation-5: -An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.
