Safety notes
All calculations happen in this browser and nothing is sent to a server.
- This is a quick balance check, not a hydrology or permitting model.
- Evaporation is estimated from area and simple climate factors, so use measured data when you have it.
- Check the unit system before sharing a result.
Što alat prikazuje
A fast summary for meetings and reports.
- 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.
Kako koristiti
- Choose the reporting period and unit system.
- Enter area, climate, inflow, drainage, reuse, and storage change.
- Load a sample if you want a starting point.
- Review the waterfall chart, breakdown table, and share URL.

Input / Output
Imperial quick check
Input
1 acre open water area, 500,000 US gal inflow, 650,000 US gal drainage, 120,000 US gal reuse, 40,000 US gal storage increase
Output
Evaporation is about 288,700 US gal and net balance is about -358,700 US gal.
Formule
- 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
Pojmovnik
- Period total
- The total volume over the selected reporting 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.
Česta pitanja
Is this a replacement for a water balance model?
No. It is a quick reporting and comparison tool.
How is evaporation estimated?
The tool multiplies a base depth by simple climate factors and the open water area.
Can I compare periods in different unit systems?
Yes. The same input state can be shared with a URL, and the unit system 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.
Napomene
- This tool is for quick balance checks and reports, not detailed hydrology.
- If the climate looks extreme, treat the evaporation estimate as a rough guide.
- Drainage that is much larger than inflow plus reuse usually means a unit mistake.
- Use the same unit system when you compare runs.
