GEOLOGY

Detailed explanation-1: -Permeability defines how easily a fluid flows through a porous material. Materials with a high permeability allow easy flow, while materials with a low permeability resist flow.

Detailed explanation-2: -Permeability refers to the ease with which water can travel through the material. In many cases, rocks or soil with high porosity will also have high permeability. The water will pass quickly through the air spaces in the rock or soil.

Detailed explanation-3: -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-4: -Permeability is a measure of the interconnectedness of pores. The connection between pore spaces allows groundwater to flow through the sediment or rock. The combination of water storage (porosity) and flow (permeability) makes a good aquifer-a rock unit or sediment that contains usable groundwater.

Detailed explanation-5: -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.
