1. What is the Pond Evaporation Rate?

The pond evaporation rate estimates the volume of water lost from a pond due to evaporation. It depends on the pond's surface area and local evaporation conditions represented by the evaporation coefficient.

2. How Does the Calculator Work?

The calculator uses the evaporation equation:

Where:

• \( \text{Rate} \) — Evaporation rate (m³/day)
• \( \text{Area} \) — Pond surface area (m²)
• \( \text{Evap Coefficient} \) — Local evaporation coefficient (m/day)

Explanation: The equation calculates daily water loss by multiplying the pond's surface area by the daily evaporation depth.

3. Importance of Evaporation Calculation

Details: Accurate evaporation estimation is crucial for water resource management, pond design, irrigation planning, and maintaining aquatic ecosystems.

4. Using the Calculator

Tips: Enter pond surface area in square meters and evaporation coefficient in meters per day. Typical evaporation coefficients range from 0.003 to 0.01 m/day depending on climate.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical evaporation coefficient?
A: In temperate climates, 0.005 m/day is common. Hot arid regions may reach 0.01 m/day, while cool humid areas may be 0.003 m/day.

Q2: How does season affect evaporation?
A: Evaporation rates are typically 2-3 times higher in summer than winter due to temperature and humidity differences.

Q3: Should wind be considered?
A: Yes, wind increases evaporation. The coefficient accounts for average local conditions including wind.

Q4: How accurate is this calculation?
A: It provides a reasonable estimate but actual rates vary daily based on weather conditions.

Q5: Can this be used for lakes?
A: Yes, the same equation applies to any water body, though large lakes may have varying coefficients across different areas.
