Tigra dam
When the Tigra Dam (Moti Lake) broke on the Shank River near Gwalior in the Gwalior district in the Indian state of Madhya Pradesh , there was a disaster on August 4, 1917, in which around 1,000 people were killed.
The Tigra dam was built in 1917 as a gravity dam made of masonry with lime mortar on a layered sandstone rock substrate. It was about 60 cm deep in the bedrock and about 25 m high. The exact height is indicated differently with 24 m, 24.7 or 25.9 m. The wall was 1.34 km long and the reservoir contained 124 million m³ of water. The well-known and important hydraulic engineer M. Visvesvaraya was significantly involved in the construction.
In the first filling of the reservoir which broke dam during a flood when it was submerged. The dam was overflowed to a height of 80 cm along its entire length. It was later calculated that a water volume of 8500 m³ / s must have flowed off. As a result, the dam wall as a whole was moved up to 14 meters over a length of 400 m. Two sections of the broken dam are said to have remained in ruins to this day.
The dam was rebuilt in 1929 with structural changes, including larger overflow openings. In 1970 there was another failure.
