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

open access: yesAtmosphere, 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 ...

New achievements on daily reference evapotranspiration forecasting: Potential assessment of multivariate signal decomposition schemes [PDF]

open access: yes, 2023
Reference evapotranspiration (ETo) is a vital climate parameter affecting plants' water use. ETo can generate large deficits in soil moisture and runoff in different regions and seasons, leading to uncertainties in drought warning systems.

Investigating the Effect of Distribution Function and Potential Evapotranspiration Assessment Method in Determining Reconnaissance Drought Index [PDF]

open access: yesعلوم و مهندسی آبیاری, 1970
Iran is located in arid and semi-arid regions in the world and therefore, drought monitoring has an important role in there. Drought assessment is conventionally based on drought indices such as Reconnaissance Drought Index (RDI).

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

open access: yesJournal 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 ...

Analysis of the Accuracy Comparison of Five Different Models of Valiantzas Equation in the Estimation of Reference Evapotranspiration [PDF]

open access: yesعلوم و مهندسی آبیاری, 2018
Evapotranspiration is one of the most important factors in hydrological cycle. Potential evapotranspiration is used to design in irrigation and drainage networks and hydrological studies (Davis & Dukes, 2010).
