Question

Water released from dams is measured in?
(A) feet per second or CFS
(B) liters
(C) Cusecs
(D) Feet

Answer 1

Hint: According to a water management perspective, there are two basic units of water measurement. When water is in motion and water is stored or impounded different types of units for measurement based on the state of water in dams.

Complete answer:
There are two conditions for which water measured in dams,
(i) When water is at rest in dams:
Water at rest like ponds, reservoirs are measured in units of volume. This measurement is considered when water storage in dams.
Common units are cubic feet.
One cubic foot = 7.4805 gallons
1 US gallon = 0.1337 cubic foot = 3.79 L
(ii) when water is in motion:
Water is in motion means when water released in dams bigger units are used for the measure the volume of water in dams or reservoirs, or river flows are TMC or Cusecs.
Cusecs are informed as cubic feet per second.
TMCft = thousand million cubic foot
1 thousand million cubic foot = $2.831X{{10}^{18}}$ L
Hence, Water released from dams is measured in Cusecs.

So, the correct answer is option C.

Note:
Calculating the dam water storage capacity needs to know the quantity of water stored in the dam to manage water supply for livestock, spraying, and other uses. The critical supply period when evaporation is high, and demand from purposes increases over summer and autumn.
