The Storage At End Of Time Interval formula calculates the amount of water stored in reservoirs within a hydrological system at the end of a time period based on the initial storage and changes in storage volumes.
The calculator uses the formula:
Where:
Explanation: The formula calculates the final storage by adding the change in storage volumes to the initial storage value.
Details: Accurate storage calculation is crucial for water resource management, hydrological modeling, and reservoir operation planning in hydrological systems.
Tips: Enter both Change in Storage Volumes and Storage at Beginning of Time Interval as positive values greater than zero. The calculator will compute the Storage at End of Time Interval.
Q1: What units should I use for the inputs?
A: Use consistent units for both inputs (e.g., cubic meters, acre-feet, or any volume unit). The result will be in the same units.
Q2: Can the change in storage be negative?
A: While mathematically possible, this calculator requires positive values greater than zero for both inputs to ensure valid hydrological calculations.
Q3: How is this formula used in hydrology?
A: This fundamental formula is used in water balance calculations, reservoir management, and hydrological modeling to track water storage changes over time.
Q4: What time intervals are appropriate?
A: The formula works for any time interval (daily, monthly, yearly) as long as consistent measurements are used for both storage values.
Q5: Are there limitations to this calculation?
A: This is a basic water balance equation that assumes accurate measurement of both initial storage and storage changes. It doesn't account for measurement errors or unaccounted water losses.
