摘要

•We use a global sensitivity analysis to assess the sensitivity of evapotranspiration to the hydrodynamic parameters.•Hydrodynamic parameter uncertainties lead to 20% to 50% uncertainties in simulated evapotranspiration.•Evapotranspiration is sensitive to the permeability in grasslands and the Van Genutchen parameters in forests.
