Change In Storage Volumes Formula:
| From: | To: |
Change in Storage Volumes (ΔSv) of water storage bodies on the stream is the difference of water incoming and outgoing. It represents the net change in water storage over a specific time period.
The calculator uses the Change in Storage Volumes equation:
Where:
Explanation: The equation calculates the net change in water storage by subtracting the observed flow volume and abstraction from the total yield of the catchment.
Details: Accurate calculation of change in storage volumes is crucial for water resource management, reservoir operations, flood control, and understanding the water balance of a catchment area.
Tips: Enter yield of catchment, observed flow volume, and abstraction in time in cubic meters. All values must be non-negative numbers.
Q1: What is Yield of Catchment?
A: Yield of Catchment refers to the total amount of water generated from a catchment area over a specific time period, influenced by precipitation, runoff, and other hydrological factors.
Q2: How is Observed Flow Volume measured?
A: Observed Flow Volume is typically measured using stream gauges that record the quantity of water flowing in a river at a particular point over a specific period.
Q3: What does Abstraction in Time include?
A: Abstraction in Time includes water withdrawn for irrigation, water supply, industrial use, and evaporation losses from surface water bodies on the stream.
Q4: What does a negative ΔSv value indicate?
A: A negative ΔSv value indicates that more water is leaving the storage system than entering it, potentially leading to depletion of water reserves.
Q5: How frequently should ΔSv be calculated?
A: The frequency of calculation depends on the specific application, but it's typically calculated daily, weekly, or monthly for effective water resource management.
