A decametre (International spelling as used by the International Bureau of Weights and Measures and by most English speaking countries, [1] [2] United States spelling dekameter or decameter [3] [4]), symbol dam ("da" for the SI prefix deca-, [1] "m" for the SI unit metre), is a unit of length in the International System of Units (SI) equal to ten metres.
11 cm = 1.1 dm – length of an average potato in the US; 13 cm = 1.3 dm – body length of a Goliath birdeater; 15 cm = 1.5 dm – approximate size of largest beetle species; 19 cm = 1.9 dm – length of a banana; 26.3 cm = 2.6 dm – length of average male human foot; 29.98 cm = 2.998 dm – distance light in vacuum travels in one nanosecond

Volumetric flow rate is defined by the limit [3] = ˙ = =, that is, the flow of volume of fluid V through a surface per unit time t.. Since this is only the time derivative of volume, a scalar quantity, the volumetric flow rate is also a scalar quantity.
The dam created a reservoir in a remote gorge of the Periyar river situated 3,000 feet above the sea in dense and malarial jungle, and from the northerly arm of this manmade waterbody, the water flowed first through a deep cutting for about a mile and then through a tunnel, 5704 feet in length and later through another cutting on the other side ...
The upper reservoir can hold about 1.5 billion US gallons (4,600 acre-feet; 5.7 million cubic metres) of water behind a wall nearly 100 feet (30 m) tall. [12] It sits 760 feet (230 m) above the 450 MW hydroelectric plant, which gives it a greater head than that of Hoover Dam. The two are connected by a 7,000-foot (2,100 m) tunnel bored through ...
In 2009, the dam, designed for a maximum flood of 19 lakh cusecs, endured a flood of 25.5 lakh cusecs. According to a survey conducted in the summer of 2018, the scouring resulted in the formation of a huge pit in the apron downstream the dam. And a structure protecting the ‘toe’ and foundation of the main dam has weakened.
Reservoir water spread of the Salaulim Dam. The dam is a composite structure of earth-cum-masonry type of 42.70 metres (140.1 ft) height above the deepest foundation level. The length of dam at the crest is 1,004 metres (3,294 ft) and the reservoir water spread area (within Goa without inter-state implications) is 24 km 2 (9.3 sq mi). [1]
