Types of Aquifers

TYPES OF AQUIFERS Aquifers are mainly of two types. Unconfined aquifer. Confined aquifer. 1. Unconfined Aquifer. The topmost water bearing strata having no confining impermeable over-burden is known as unconfined aquifer. This aquifer is also know non-artesian aquifer or water table aquifer. Water table in such an aquifer varies in undulating form depending upon the storage of water within it. The gravity wells are construct to tap water from unconfined aquifer only. The water rise in such wells is equal to water rise in a piezometer connected to the water table.   2. Confined Aquifer. It is such an aquifer which remains overladen by an impermeable strata or aquiclude. The water is under pressure in this aquifer. Confine aquifers are also know as artesian aquifers. They can be consider analogous to pipe lines flowing under pressure. The static pressure at a point in a confin aquifer is equal to the…
