Abstract
This paper presents the application of the Variable Infiltration Capacity (VIC), a macroscale hydrological model, to the Pearl River basin in South China. Meteorological data at 1 degree by 1 degree grids from 1951 to 2000 over the region are used to drive the model at a daily time step. The values of the parameters of soil and vegetation data for the model are extracted from two global datasets. A large-scale routing scheme for the VIC model is applied to route the runoff from the upstream to the downstream of the Pearl River. The simulation results are compared with the observed streamflows, at monthly and annual scales, obtained from three streamflow gauge stations. It is observed that the model and routing scheme can give a reasonable simulation.
