How do you calculate reservoir capacity?
How do you calculate reservoir capacity?
The variable St is calculated by the following equation: St = | St-1 + Rt – It | 0 if negative or zero if positive (1.2) The required storage capacity is equal to the maximum of St values. Example 1.1: A reservoir is to be constructed at a location where monthly flow data are available for 28 months.
What is capacity of reservoir?
Reservoir Capacity means the gross volume of water which can be stored in the reservoir.
What is reservoir yield?
“Reservoir Yield” means the quantity of water which can be withdrawn from storage in the reservoir. Reservoir yield is determined by the rate of flow of the stream into the reservoir, losses due to evapotranspiration from the reservoir surface, and the volume of water impounded in the reservoir (K.A.R. 98-5-1k).
How do you calculate sedimentation in a reservoir?
Standard practice is to calculate the reservoir life by dividing the usable storage volume by the average amount sediment deposited annually. However, in many reservoirs, the economic life is reached when the useful storage volume varies from 50% to 80% of the original total capacity [4, page 1].
How do you calculate the amount of water in a lake?
If your lake or pond is rectangular in shape — multiply the lake’s length, width, and average depth and divide by 43,560 to find its volume in acre-feet.
What is full reservoir level?
Full Reservoir Level means the level of water in a reservoir corresponding to conservation Storage Capacity.
What is the water storage capacity of reservoir is expressed in?
In most of the world, reservoir areas are expressed in square kilometres; in the United States, acres are commonly used. For volume, either cubic metres or cubic kilometres are widely used, with acre-feet used in the US. The capacity, volume, or storage of a reservoir is usually divided into distinguishable areas.
What is capacity inflow ratio?
Explanation: Capacity-inflow ratio can be defined as the ratio of the reservoir capacity to the total inflow of water.
How do you calculate sediment yield?
† Sediment yield is calculated using the Renard (1972) equation converted to metric units with a sediment density of 1.2 Mg/m3. where Qs = streamflow sediment yield (Mg/yr) and A = drainage area (km2).
What is sediment volume?
Sediment volume was calculated by subtract- ing the volume of the current water-storage capacity from the volume of the 1972 original storage capacity in the same area.
How do you calculate water volume in litres?
Dividing the volume (in cubic centimeters) of the shape by 1,000 will give you the volume in liters (L). . So, a fish tank that is 40.64 cm long, 25.4 cm wide, and 20.32 tall has a volume of 20.975 L.
How do you calculate the amount of water?
- Divide your weight in pounds by 2.2.
- Multiply the result by the number below that applies to your age range: If you’re younger than 30, multiply by 40. If you’re 30–55 years old, multiply by 35.
- Divide your result by 28.3. The answer is the estimated amount of water you require each day, in ounces.
