Investigating Hydrological Variability in the Wuding River Basin: Implications for Water Resources Management under the Water–Human-Coupled Environment

چکیده
Understanding and quantifying changes in hydrological systems due to human interference are critical for the implementation of adaptive management global water resources changing environment. To explore implications variations management, Wuding River Basin (WRB) Loess Plateau, China, was selected as a case study. Based on Budyko-type equation with time-varying parameter n, human-induced water–energy balance (HWEB) model proposed investigate variability WRB. The investigation showed that runoff continuously reduced by 0.424 mm/a during 1975–2010, weakly reducing precipitation increasing groundwater exploitation causing decrease storage at rate 1.07 mm/a, actual evapotranspiration accounting more than 90% having an insignificantly decreasing trend 0.53 under climate change (decrease) impact (increase). Attribution analysis indicated underlying surface condition played dominant role reduction driving increase evapotranspiration, mainly impacted overall compounded entire period. It is suggested watershed controlling should receive greater attention future basin management.
