Potential evapotranspiration

Evapotranspiration plays a big role in the hydrology process. Potential Evapotranspiration (PET) always keeps soil moisture available, although an amount of water The monthly potential evapotranspiration Ep using the Thornthwaite (1948) method after its adjustment for variable daylight and month lengths (Willmott et al., 1985) is estimated as follows:

Evapotranspiration estimation methods in hydrological models

Explanation: The Thornthwaite method is used to estimate potential evapotranspiration (ET‘) based on temperature data. The formula for unadjusted monthly potential evapotranspiration Such assessments are often driven by estimations of potential evapotranspiration (ETP) and/or reference evapotranspiration (ET0), yet no comprehensive and validated

Evapotranspiration time series are calculated based on the daily minimum and maximum air temperatures and specific monthly coefficients using Hamon’s potential Although the accurate prediction of the Standardized Precipitation Evapotranspiration Index (SPEI) is considered meaningful in reducing drought losses

Potential evapotranspiration (PET) is a significant factor contributing to water loss in hydrological systems, making it a critical area of research. However, accurately calculating
