DAMS
Dams
• Dam is a solid barrier constructed at a suitable
location across a river valley to store flowing water.
• Storage of water is utilized for following objectives:
• Hydropower
• Irrigation
• Water for domestic consumption
• Drought and flood control
• For navigational facilities
• Other additional utilization is to develop fisheries

Upstream Down stream
• Heel: contact with the ground on the upstream side
• Toe: contact on the downstream side
• Galleries: small rooms like structure left within the dam for checking
operations.
• Spillways: It is the arrangement near the top to release the excess water
of the reservoir to downstream side
• Sluice way: An opening in the dam near the ground level, which is used
to clear the silt accumulation in the reservoir side.
TYPES OF DAMS
• Gravity Dams:
• These dams are heavy
and massive wall-like
structures of concrete
in which the whole
weight acts vertically
downwards
Reservoir
Force
As the entire load is transmitted on the small area of foundation, such
dams are constructed where rocks are competent and stable.
• Bhakra Dam is the highest
Concrete Gravity dam in
Asia and Second Highest
in the world.
• Bhakra Dam is across river
Sutlej in Himachal Pradesh
• The construction of this
project was started in the
year 1948 and was
completed in 1963 .
• It is 740 ft. high above the deepest foundation as straight concrete dam being more than three times
the height of Qutab Minar.
• Length at top 518.16 m (1700 feet); Width at base 190.5 m (625 feet), and at the top is 9.14 m (30
feet)
• Bhakra Dam is the highest Concrete Gravity dam in Asia and Second Highest in the world.
Buttress Dam:
• Buttress Dam – Is a
gravity dam reinforced by
structural supports
• Buttress - a support that
transmits a force from a
roof or wall to another
supporting structure
This type of structure can be considered even if the foundation
rocks are little weaker
• These type of dams are
concrete or masonry dams
which are curved or convex
upstream in plan
• This shape helps to transmit
the major part of the water
load to the abutments
• Arch dams are built across
narrow, deep river gorges, but
now in recent years they have
been considered even for little
wider valleys.
Arch Dams:
Earth Dams:
• They are trapezoidal in
shape
• Earth dams are
constructed where the
foundation or the
underlying material or
rocks are weak to support
the masonry dam or where
the suitable competent
rocks are at greater depth.
• Earthen dams are
relatively smaller in height
and broad at the base
• They are mainly built with
clay, sand and gravel,
hence they are also known
as Earth fill dam or Rock
fill dam
