Popis:	The river flow is indispensable to the hydrologic cycle. But in the Atmospheric General Circulaton Model, the river flow is always ignored. So in this paper, we make a global river direction file for T21 grid resolution, at first, and then make a river routing model and calculate it. As input, we use runoff from the CCSR/NIES AGCM (T21 resolution). After calculation, we analyze the results of some world major basins by comaparing the results of model with observations. As a result of this paper, we reproduce seasonal changes of discharge better than before.
