Mining Water Balance Reiknivél
Estimate a mining site water balance from inflæði, drainage, reuse, evaporation, and storage change in one place.
Period totals, daily averages, a waterfall chart, and shareable URLs stay in the browser.
Safety notes
All calculations happen in this browser and nothing is sent to a server.
- This is a quick balance check, not a hydroskráy or permitting model.
- Evaporation is estimated from area and simple climate factors, so use measured data when you have it.
- Check the unit kerfi before sharing a niðurstaða.
What this verkfæri shows
A fast summary for meetings and skýrslas.
- Period total and daily average are derived from the same calculation.
- Climate zone and local conditions adjust the evaporation estimate.
- Shareable URLs can reproduce the current state.
How to use it
- Choose the skýrslaing period and unit kerfi.
- Enter area, climate, inflæði, drainage, reuse, and storage change.
- Load a sample if you want a starting point.
- Yfirferð the waterfall chart, breakdown tafla, and share URL.

Formulas
- tempFactor = clamp(1 + (temperature - 20) × 0.025, 0.65, 1.45)
- humidityFactor = clamp(1 - (humidity - 50) × 0.0035, 0.55, 1.25)
- climateFactor = clamp(tempFactor × humidityFactor × windFactor × sunFactor, 0.5, 1.8)
- evaporation = area × depth × period
- net balance = inflow + reuse - drainage - evaporation - storage change
Glossary
- Period total
- The total volume over the selected skýrslaing period.
- Daily average
- The period total divided by the number of days.
- Climate factor
- A simple multiplier that adjusts the base evaporation depth.
- Storage change
- Water added to or removed from storage during the period.
Algengar spurningar
Is this a replacement for a water balance model?
No. It is a quick skýrslaing and samanburður verkfæri.
How is evaporation estimated?
The verkfæri multiplies a base depth by simple climate factors and the open water area.
Can I bera saman periods in different unit kerfis?
Yes. The same inntak state can be shared with a URL, and the unit kerfi is stored with it.
Can I leave the open water area at zero?
Yes. Evaporation becomes zero and the rest of the balance still works.
Athugasemdir
- This verkfæri is for quick balance checks and skýrslas, not detailed hydroskráy.
- If the climate looks extreme, treat the evaporation estimate as a rough guide.
- Drainage that is much larger than inflæði plus reuse usually means a unit mistake.
- Use the same unit kerfi when you bera saman runs.
