What is the meaning of perched water?

: groundwater occurring in a saturated zone separated from the main body of groundwater by unsaturated rock.

What are two types of aquifer?

Aquifers are generally been classed into two main categories namely confined aquifer and unconfined aquifers.

2.1. Confined aquifers. Confined Aquifers are those bodies of water found accumulating in a permeable rock and are been enclosed by two impermeable rock layers or rock bodies.
2.2. Unconfined aquifer.

What are the benefits of extracting water from a perched aquifer?

Perched or mounded groundwater may act as a partial surrogate for regional groundwater that normally surrounds streams by limiting seepage loss, providing base flow and bank storage.

How do you drain a perched water table?

The way to increase drainage of the perched water table is to add materials throughout all of the potting medium to increasing the air spaces in the mix and reduce capillary action. Some plants require extremely well draining potting mixes in containers.

What is called aquifer?

Aquifer, in hydrology, rock layer that contains water and releases it in appreciable amounts. The rock contains water-filled pore spaces, and, when the spaces are connected, the water is able to flow through the matrix of the rock. An aquifer also may be called a water-bearing stratum, lens, or zone.

Where are perched aquifers found?

Perched aquifers occur above discontinuous aquitards, which allow groundwater to “mound” above them. Thee aquifers are perched, in that they sit above the regional water table, and within the regional vadose zone (i.e. there is an unsaturated zone below the perched aquifer).

What is above the aquifer?

The potentiometric surface is an imaginary surface above the aquifer, to which water from an artesian aquifer would rise in a pipe. The term potentiometric surface means head- or potential-indicating surface and is preferable to the term piezometric surface, which is found in some literature.

What is the upper level of an aquifer Calle?

The upper level of this saturated layer of an unconfined aquifer is called the water table or phreatic surface. Below the water table, where in general all pore spaces are saturated with water, is the phreatic zone .

What is top of aquifer?

The boundaries of an aquifer are usually gradational into other aquifers, so that an aquifer can be part of an aquifer system. The top of an unconfined aquifer is the water table.
