different types of wells

1. Multitude of wells
• Wells are common in our locality. The upper
level of the water table forms the water level
in the well.
• It is difficult to dig wells where the water table
is deep. Tubewells are ideal in such
situations.

3. • The term filter point wells are used for the
shallow tube wells dug in sandy regions.

5. • There be permeable rock layer in between two
impermeable rock layers.
• Water will rise to the surface automatically due to
pressure if we dig to this permeable rock layer.
Such wells are known as artesian wells.
• The availability of water is due to the entry of
water at some point to the permeable rock layer.

7. • Small streams found in the hill slopes and
courtyards during rainy seasons.
• At some places these will have regular flow
while it dries up at many instances soon after
the end of rainy season.
• Water will be flowing out along the surface
wherever water table touches the ground. This
is known as Spring.
• At some places such water flows are
characterised with hot water. These are known
as hot springs

9. • The phenomenon of severe ejection of water
from within the earth at regular intervals is known
as Geysers
example: The old faithful geyser of yellow stone
national park, USA
• The water that seeps through the fissures on
the earth comes contact with the magma and
leads to the formation of hot springs and
geysers.
