In acrh dam the load is distributed on both the side of dam
as well as load is transfered in circular form on the
ground. where as in gravity dam load is transfered strait
to the ground. and kakrapar dam on river tapi is the
exampal of the gravity dam.

Answer / don

The difference is in the load distribution mechanism
employed.Here the load is the force exerted by the water
being stopped in the direction of flow.An arch dam as the
name implies, uses an arc shape built between two sturdy
supports(rocky mountains for eg)and the load is transferred
laterally to the supports.A gravity dam relies on its own
weight to prevent toppling down by the load.Imagine them
like the concrete blocks, the traffic police keeps on roads
to regulate or block traffic in certain directions.They have
a wide base and are heavy weight.

Answer / narendra

Unlike the concrete gravity dams, arch dams use a special
arch shape (curved toward upstream) to transfer the force
to the two sides of the valley and the foundation.
Idukki Dam is the first Arch Dam in India,
kakrapar dam on river tapi is the
exampal of the gravity dam.

Answer / sivaraj

the length of the arch dam is less and depth is high. the arch dam distributes on both side of dam.

Answer / ouseph joy

An arch dam having a curved surface transfers the forces acting on it laterally to the foundation.In the case of gravity dam, the dam's self weight is used to resist the forces acting on it.
