Pond Flow Rate Calculator
Actual pond replacement volume PLUS signed storage change over actual observed time inflow bookkeeping, not volume/desired retention forecast.
Description
Observed pond inflow accounting must include both displaced water and signed storage change.
Observed pond inflow accounting must include both displaced water and signed storage change.1
This tool divides their sum by observation duration without selecting a replacement schedule.
When to use Pond Flow Rate Calculator
Use this tool to calculate their sum by observation duration without selecting a replacement schedule.
How to use Pond Flow Rate Calculator and how it works
- Establish the observations, units, reference context and assumptions described below.
- Enter actualPondDisplacedWaterVolume, actualObservedStorageVolumeChange, actualObservationSeconds and run the tool.
- Read result.value using the meanings and sign conventions below.
- Correct any rejected inputs and rerun; independently review the result under the stated scope.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualPondDisplacedWaterVolume | Nonnegative displaced pond water volume during the observation period. | number | Required; finite; nonnegative; branch conditions below |
| actualObservedStorageVolumeChange | Signed storage change on the same volume and period basis; total with displaced volume must be nonnegative. | number | Required; finite; branch conditions below |
| actualObservationSeconds | Positive elapsed observation duration in seconds. | number | Required; finite; strictly positive; branch conditions below |
Supply nonnegative displaced water volume, finite signed observed storage-volume change in the same volume unit and positive observation duration in seconds. Require displaced+storageChange>=0, then divide that sum by seconds. A negative storage change is allowed if the total stays nonnegative; the sign convention and complete water ledger are caller-established.
observedInflowVolumePerSecond=(displacedVolume+signedStorageChange)/observationSeconds Use the stated ordering, units and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the fields below. | object |
| result.value | Observed inflow in the supplied volume unit per second. | number |

}Limitations and assumptions
The calculation depends on independently established observations, coefficients and the matching units. It does not collect data, choose a treatment or target, establish model applicability or provide a validated forecast. Interpret its result within the branch conditions and assumptions above.
Supply explicit values and dense aligned arrays. Unexpected fields, wrong types and nonfinite scalar values are rejected; fixed-token, alignment and other branch conditions are explained above. A successful false flag, empty match list or unknown-evidence list differs from an input error. Extremely large inputs or nonrepresentable results may fail.

Use Cage Volume Calculator for a related operation: A net cage's actual enclosed volume can change with its measured deformation.
