Description
A recharge fraction summarizes the portion of precipitation assigned to groundwater recharge under an independently established model.
A recharge fraction summarizes the portion of precipitation assigned to groundwater recharge under an independently established model.1
This tool multiplies a matched precipitation depth by that fraction without estimating infiltration, runoff or evapotranspiration.
When to use Recharge Estimate from Precipitation Fraction Calculator
Use this tool to apply the stated recharge estimate from precipitation fraction calculator operation with an explicit input and unit basis.
How to use Recharge Estimate from Precipitation Fraction Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualMatchedPrecipitationDepth, callerIndependentApplicableRechargeFraction and run the tool.
- Read result.value using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualMatchedPrecipitationDepth | Matched Precipitation Depth. Units, ordering and applicable branch are specified in the algorithm. | number | required; finite; nonnegative; further conditions in the algorithm |
| callerIndependentApplicableRechargeFraction | Applicable Recharge Fraction. Units, ordering and applicable branch are specified in the algorithm. | number | required; finite; 0–1 inclusive; further conditions in the algorithm |
Require nonnegative precipitation depth and recharge fraction in [0,1]. Multiply them on the matched spatial and time basis; output retains the input depth unit.
conditionalRechargeDepth = precipitationDepth × rechargeFraction Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Conditional recharge depth in the precipitation depth unit. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A returned boolean, signed difference or tied result follows the stated convention; an input error instead means the required input contract was not satisfied. Very large inputs or outputs may be rejected by shared resource limits.
