AbstractDespite offering spatially and temporally continuous measurements, the use of remotely sensed P and E in data‐scarce catchments is hindered by the lack of ground‐based measurements that enable comprehensive validation. This study proposes a novel validation framework that characterizes the combined error in the long‐term average estimates of ...

Summary Catchment hydrological processes have been greatly influenced by the intensive variability in land use/cover, precipitation and air temperature due to climate change and local human activities. It is desired to understand catchment hydrological response to these changes.

The Wei River Basin (WRB), the largest tributary of the Yellow River in China, has experienced a noticeable decrease in annual runoff during the last 50 years. Quantifying the relative contributions of climate change and human activities on runoff changes is thus important for local water resources management and sustainable water resources ...

On the basis of long time series of climate and discharge in 108 nonhumid catchments in China this study analyzes the spatial and temporal variability of annual water‐energy balance using the Budyko hypothesis. For both long‐term means and annual values of the water balances in the 108 catchments, Fu's formula derived from the Budyko hypothesis is ...

Abstract Streamflow has been complexly altered by climate change and human activities in major rivers worldwide. The traditional Darwinian approach for impact assessment of climate change and human activities mainly focuses on variations in annual streamflow, but ignores other critical streamflow characteristics (e.g., high- and low-flow signatures).

Science of the Total Environment
This study coupled the green water and blue water accounting with the existing standard Budyko framework and Fu's 1-parameter Budyko framework to diagnose the basin hydrological behavior. Both Budyko frameworks were employed to determine green water consumption (ETGreen) and blue water consumption (ETBlue) which, in turn, were used to map the blue ...

The complementary relationship and generation of the Budyko functions [PDF]
Geophysical Research Letters, 2015 The Budyko hypothesis states that the ratio of the actual evapotranspiration over precipitation (E/P) is fundamentally related to the ratio of the potential evapotranspiration over precipitation (E0/P).

The Budyko hypothesis before Budyko: The hydrological legacy of Evald Oldekop
Journal of Hydrology, 2016Summary 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 = Ex/P (where P represents long-term precipitation [mm/yr] and Ex long-term maximum evaporation [mm/yr]).

AbstractThe 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. Based on the equations of Choudhury and Porporato, the actual evapotranspiration trends and the runoff trends are attributed to changes in precipitation ...
