Mass-Transfer (Aerodynamic) Method
An evaporation estimate based on wind speed and the vapor-pressure deficit between the water surface and the air, using an empirically calibrated transfer coefficient. It treats evaporation as wind-driven removal of water vapor from the surface.
Because it directly captures wind and the surface-to-air humidity gradient, the aerodynamic mass-transfer approach is robust for industrial ponds and other open-water sites. Classic formulations trace to Harbeck (1962) and the Lake Hefner studies.
