Description
Return rechargeVolume = area*rechargeDepth*fractionReachingAquifer.
A volume estimate connects an area and depth, a flow and time, or a storage balance. Coherent units and explicit reserves distinguish physical volume from usable capacity; a valid quantity balance does not establish water quality or structural adequacy.
Return rechargeVolume = area*rechargeDepth*fractionReachingAquifer.
When to use this tool
Use Groundwater Recharge Area Depth Volume when checking a supplied volume conversion, reserve or storage balance.
How to use the tool and how it works
- Enter area, rechargeDepth, fractionReachingAquifer. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read rechargeVolume. Use the output convention below.
Require nonnegative area and rechargeDepth and fractionReachingAquifer in [0,1]. Return rechargeVolume = area*rechargeDepth*fractionReachingAquifer. Convert area and depth into coherent units before multiplication.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| area | Area on the coherent length basis required by the volume or loading formula. | Required. Finite number; minimum 0. |
| rechargeDepth | Recharge Depth | Required. Finite number; minimum 0. |
| fractionReachingAquifer | Fraction Reaching Aquifer | Required. Finite number; minimum 0; maximum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| rechargeVolume | Recharge Volume | Required. Finite number. |

}Limitations and assumptions
- The fraction is an explicit assumed transfer factor. The tool does not estimate it from soil or rainfall, solve groundwater flow, or establish aquifer replenishment timing and water quality.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a hydraulic model, actual tank geometry and qualified design criteria when time-varying flow or practical capacity matters.
