WebApr 11, 2024 · The actual evapotranspiration and runoff trends of five major basins in China from 1956 to 2000 are investigated by combining the Budyko hypothesis and a stochastic soil moisture model. WebApr 1, 2016 · In the hydrological jargon, the Budyko hypothesis refers to the hypothesis according to which the long-term water and energy balances of the Earth’s surface are largely dependent upon a single aridity ratio φ = E x /P (where P represents long-term precipitation [mm/yr] and E x long-term maximum evaporation [mm/yr]). In this historical …

Differently, the Budyko hypothesis is based on water-heat balance and has clear physical meanings and has been widely applied in previous studies (Budyko 1974; Dooge 1992; Choudhury 1999; …
WebDec 17, 2015 · The Budyko hypothesis provides a reference condition of water balance and describes an empirical relationship between precipitation (P), evapotranspiration (E) and potential evapotranspiration (Ep). However, real-world catchments often deviate significantly from the theoretical Budyko curve. Recent advances of understanding in the impacts of … WebRecently, climate elasticity and decomposition methods based on the Budyko hypothesis have been extensively used to quantify the climate- and human-induced streamflow changes. These two approaches are more reasonable and credible compared to other statistical methods due to the inclusion of basic physical processes [43,44]. Furthermore, …
