TMC is a measurement of volume. It is an abbreviation of Thousand Million Cubic feet. This is equal to 283.17 megalitres.
TMC =Ten Million Cubic feet Million = 1000000( In new SI-International system -Mega-M)
Ten Million=10000000 1 feet = 12X 2.54 cm =30.48cm =0.3048m
1 cft = 1 feet X 1feet X 1feet = 0.3048 X 0.3048 X 0.3048 metre cube (m3)
1 m3 = 1/(0.3048 X 0.3048X0.3048) = 35.31466672 cft
1Mm3 =35.31466672X 1000000 cft
1 Mm3 =3.531466672 TMC
1TMC = 1/3.531466672 Mm3 = 0.283168465 Mm3 nearly = 0.28317 Mm3= 0.28317X 1000 M litres
1TMC =283.17 Mega litres

The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
From the power of falling water. Usually engineered to take advantage of a high dam where the water level inside the dam is kept at a high level. See the Boulder Dam for example. The water is fed through turbines which then drive electric generators. From the environmental viewpoint this is ideal as no greenhouse gases are evolved, and the energy is renewable. Also once the dam and equipment are built, there are no costs apart from general maintenance costs, and operating staff costs.
A dam is built, normally across a river but sometimes across a lake or even the sea, in a suitable place. Anyway, once the dam is built, water cannot pass through so it builds up on one side - so that you have a dam with a high water level on one side and no water on the other. There are passages built into the bottom of the dam which contain turbines, and once the water level reaches a sufficient height these passages are opened and water can pass through from the 'high level' side to the 'no water' side (obviously). As the water goes through the passages it spins the turbines which in turn spin electrical generators, creating electricity.
The pressure that water exerts on the walls of the dam is proportional to the depth of the water or you might say the height of the column of water from the base of the dam. The hydraulic height is the same as the depth of the water to the bottom of the dam.
8 tmc
approximately 20 TMC
1234
100 tmc
more than one thousand TMC.
koyna dam 100 TMC capacity is a wrong answer. the correct answer is UJANI DAM on bhima river capacity is 117 tmc. 2 nd is Jayakwadi project on GODAVARI RIVER capacity is 103 tmc.
118 tmc
Water pressure on the dam.
Any dam will raise the water level behind it.

A barrage is a type of dam that uses gates to control the level of water. They were built to divert water or to dam a lagoon.
