Abstract: Variable Infiltration Capacity or VIC model is a distributed land surface hydrological model based on cell-grids. Because of its ability to be coupled with climate models, VIC model is widely applied to reveal the impact of climate change on water cycle. As a result, it can provide powerful decision support in dealing with climate change issues on a regional or watershed scale. In this paper, a VIC model is built in the Nanliujiang River basin of China and the sensitivities of the model parameters are analyzed. Then, the water resources under different future climate scenarios are predicted by coupling five climate models with the VIC model. The research results show that the VIC model is applicable to modelling the runoff in the Nanliujiang River basin, the fraction of maximum soil moisture where non-linear baseflow occurs, the variable infiltration curve parameter and the thickness of the second soil moisture layer in the VIC model are sensitive, and that water resources in the Nanliujiang River basin present an increasing trend under different future climate scenarios. However, the variation trends are different under climate models
