GENERAL GEOLOGY

Detailed explanation-1: -An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it.

Detailed explanation-2: -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. Diagrams illustrating poor permeability and good permeability.

Detailed explanation-3: -The ease with which fluid is transmitted through a rock’s pore space is called permeability. Although a rock may be very porous, it is not necessarily very permeable. Permeability is a measure of how interconnected the individual pore spaces are in a rock or sediment.

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: -A wet underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well.
