Deriving potential evapotranspiration from satellite-based reference evapotranspiration, Upper Tekeze Basin, Northern Ethiopia

Journal of Hydrology: Regional Studies, 2022
Study region: Zamra catchment, Upper Tekeze Basin, Northern Ethiopia. Study focus: Direct field estimates of potential evapotranspiration (PET) remain a challenge, because they are expensive and have limited spatial representativeness.

Performance of potential evapotranspiration models in Peninsular Malaysia

Journal of Water and Climate Change, 2021
Potential evapotranspiration (PET) is an important parameter for the operation of irrigation projects and water resources management. The globally recognized PET estimation model, the FAO-56 Penman–Monteith (FAO-56 PM) model, had been criticized for ...

A MODEL FOR ESTIMATING ACTUAL EVAPOTRANSPIRATION FROM POTENTIAL EVAPOTRANSPIRATION [PDF]

Hydrology Research, 1975
A model for calculating the daily actual evapotranspiration based on the potential one is presented. The potential evapotranspiration is reduced according to vegetation density, water content in the root zone, and the rainfall distribution. The model is tested by comparing measured (EAm) and calculated (EAc) evapotranspirations from barley, fodder ...

Simulation of potential evapotranspiration values based on vine copula

Meteorological Applications, 2021
Vine copula had a great impact on the study and analysis of dependence structures in various sciences. In multivariate analyses with dimensions of more than two variables, it is associated with computational complexities that solve vine copulas and these

Spatiotemporal Changes of sc-PDSI and Its Dynamic Drivers in Yellow River Basin

Atmosphere, 2022
Droughts in the Yellow River Basin (YRB), a typical large river in arid to semiarid regions, have been studied extensively. However, the details of the dynamic drivers of meteorological droughts, such as precipitation (P), reference evapotranspiration ...

Effect of projected climate change on potential evapotranspiration in the semiarid region of central India

Journal of Water and Climate Change, 2021
The performance of potential evapotranspiration (PET) methods such as pan evaporation (physical measurement), empirical formulas (Penman–Monteith (PM), Hargreaves and Thornthwaite) and satellite-derived PET (MOD16) were assessed in a semiarid region of ...
