Metric quick check
Input
10,000 m² open water area, 15,000 m³ inflow, 12,000 m³ drainage, 4,500 m³ reuse, 800 m³ storage increase
Output
Evaporation is about 900 m³, net balance is about +5,800 m³, and reuse share is about 23%.

Mining Water Balance Calculator
Estimate a mining site water balance from inflow, drainage, reuse, evaporation, and storage change in one place.
Period totals, daily averages, a waterfall chart, and shareable URLs stay in the browser.

Оролтууд зөвхөн энэ хөтөч дээр боловсруулагдана, сервер рүү илгээгдэхгүй.
- 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.
What this tool shows
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.
How to use it
- 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.
Examples
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.
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 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.
Түгээмэл асуултууд
Энэ нь усны балансын моделиудыг орлох уу?
Үгүй. Энэ бол хурдан тайлан ба харьцуулалтын хэрэгсэл юм.
Ууршилтыг хэрхэн тооцдог вэ?
Энэ хэрэгсэл нь суурь гүнг энгийн уур амьсгалын хүчин зүйлс болон ил усны талбайгаар үржүүлдэг.
Өөр өөр нэгжийн системтэй хугацаануудыг харьцуулж болох уу?
Тийм. Ижил оролтын төлөвийг URL-ээр хуваалцаж болох бөгөөд нэгжийн систем мөн хамт хадгалагдана.
Ил усны талбайг тэгээр үлдээж болох уу?
Тийм. Ууршилт тэг болж, үлдсэн баланс хэвийн ажиллана.
Notes
- 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.
