Question:
Which of the following is a method for estimating evaporation from a water surface?
Which of the following is a method for estimating evaporation from a water surface?
Show Hint
Penman method requires inputs like net radiation, air temperature, humidity, and wind speed, making it reliable for evaporation estimation.
Updated On: Jun 17, 2025
- Darcy's law
- Penman method
- Rational method
- Gumbel's method
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The Penman method is a widely used and accurate technique for estimating evaporation and evapotranspiration. It combines energy balance and mass transfer approaches.
Explanation of Options:
- Darcy's law: Related to groundwater flow, not evaporation.
- Rational method: Used for estimating peak runoff from rainfall, not evaporation.
- Gumbel's method: Statistical method for flood frequency analysis.
Hence, only the Penman method is suitable for estimating evaporation.
