In continental and global scale modelling of land surface processes, stream flow, lateral movement of channel water within a channel network is an important component. It is an indispensable component in a fully coupled atmosphere-ocean-land general circulation models (GCMs). The aim of this study is to develop a synthetic runoff routing model for continental-scale river basins. Considering the resolution of typical GCMs, the model resolution is set to 1.0°. This model is designed to accept runoff generated in grid cells within a river basin, and route them to assigned points through a channel network. In this routing model, three routing schemes, Miller's scheme, kinematic wave model and multi-step multi-reachMuskingum-Cunge scheme are implemented. By applying this routing model to theChangjiang and Mississippi river basin, intercomparison of these three routing schemes is carried out.
