How do you find the volume of water in a reservoir?

To do this:

1. Square the length of the contour line;
2. Divide the result by 37.5 (conversion factor);
3. Multiply by the assumed maximum water depth (in this case, 1.5 m) to find the approximate reservoir volume.

How do you measure the water level of a dam?

The steps are:

1. Measure or pace the sides or circumference of the dam at the elevation of the spillway discharge.
2. Measure the difference in height between the current water surface and the spillway discharge.
3. Add this measurement to the current depth to calculate the water depth when the dam is full.

How do you calculate water discharge from a dam?

To calculate the water flow (in m3/s) multiply the average water velocity by the average cross-section. To express this water flow in litres per second (l/s), multiply the result (in m3/s) by 1000. 0.486 m3/s x 1 000 = 486 l/s.

What is dam and reservoir?

Dams are structures that restrict the flow of water in a river or stream. Once a body of flowing surface water has been slowed or stopped, a reservoir or lake collects behind the dam. Dams and reservoirs exist in nature, and man-made water control structures are patterned after examples in the natural word.

Is the volume of water in a reservoir discrete or continuous?

Volume is continuous, so the amount of water would be represented by a continuous random variable. The number of minutes is countable, so it would be a discrete variable.

How can water be measured?

There are two basic units of water measurement from a water management perspective. For water that is in motion, cubic feet per second (cfs) is the unit of measure. For water that is stored or impounded, the acre-foot (af) is how water is measured. Cubic feet per second (cfs):

Which unit is used to measure dam water?

Answer Expert Verified The water in the dams is considered as stored water or impounded water. It can be measured either in terms of ‘Cusecs’ or as ‘Tmcft’. Cusec is the informal shorthand for “cubic feet per second”. It can be converted to 28.317 litres per second.

How do you calculate water discharge?

Discharge = V x D x W If length is measured in feet and time in seconds, Discharge has units of feet3/sec or cubic feet per second (cfs). Depth times Width gives the cross-sectional area.

How is water distributed in reservoirs?

Storing water at a high elevation in a lake or reservoir can produce pressure. Where water is pumped from the ground it is stored in special tanks on hilltops. In urban and suburban areas, water is distributed from the source through large underground pipes, called water mains, under the streets.

How is a reservoir built?

A dam is usually constructed across a river to create a reservoir in the valley behind by storing the water that flows into it naturally. Sometimes, they are built across dry valleys, or valleys with small streams, to create a storage area for water that is transported from elsewhere.

How is the water level at a dam calculated?

IT IS CALCULATED BASED ON THE OCEAN SEA LEVEL…that is to say…if a lake is calculated to be….say….323 ft level…then it is 323ft above sea level…. Originally Answered: how water level at dam is calculated? There are a few ways of doing it.

How do you calculate the capacity of a reservoir?

In this case also the required capacity of the reservoir can be determined in the same way by superimposing the demand curve on the mass curve from the high points (or beginning of the dry period) till the two meet again. The largest vertical intercept between the two curves gives the required reservoir capacity.

How do you find the total demand for a reservoir?

For example assuming the reservoir to be full at G, for a period corresponding to points G and Z 1, there is a total flow in the stream represented by Y 1 Z 1 and there is a total demand represented by X 1 Z 1 leaving a gap of volume represented by X 1 Y 1 which must be met with from the reservoir storage.

What is the inflow and outflow rate of a dam?

600000/60 cum. water entering into reservoir and 100000/60 cum. water is outgoing every second. Inflow and outflow of dams are calculated in cusecs (cubic foot per second). Inflow or outflow is called as discharge of a river.
