Epikarst Storage Estimate Calculator
Actual epikarst area×independently resolved effective storage thickness×drainable porosity. Not total porevolume, infiltration kinetics or guaranteed water resource.
Description
Epikarst drainable storage can be modeled from footprint, effective thickness and drainable porosity.
Epikarst drainable storage can be modeled from footprint, effective thickness and drainable porosity.1
Those independently established terms differ from total rock volume or total porosity.
When to use Epikarst Storage Estimate Calculator
Use this tool to obtain conditionalEpikarstDrainableStorageCubicMeters from the supplied records using the stated calculation. Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
How to use Epikarst Storage Estimate Calculator and understand its results
- Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
- Enter actualEpikarstFootprintSquareMeters, callerIndependentEffectiveStorageThicknessMeters, callerIndependentDrainablePorosityFraction, using the field meanings and rules below, then run the tool.
- Read result.conditionalEpikarstDrainableStorageCubicMeters. Use the units and sign conventions below, and review any unknown records separately.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualEpikarstFootprintSquareMeters | Actual epikarst footprint square meters | number | Required |
| callerIndependentEffectiveStorageThicknessMeters | Caller independent effective storage thickness meters | number | Required |
| callerIndependentDrainablePorosityFraction | Caller independent drainable porosity fraction | number | Required |
Require nonnegative footprint area and effective storage thickness, plus drainable porosity in [0,1]. Multiply them for the conditional drainable volume in cubic metres. Neither thickness nor porosity is inferred.
storageM3=areaM2×effectiveThicknessM×drainableFraction Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observed calculation or explicit reference | object |
| result.conditionalEpikarstDrainableStorageCubicMeters | Conditional Epikarst Drainable Storage Cubic Meters | number |

}Limitations and assumptions
The actual observation coverage, calibration and qualified plan determine applicability. A numerical result does not establish survey accuracy, route suitability, atmosphere conditions or equipment adequacy beyond the declared comparison.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
