Even thought the distribution of the rainfall in the watershed is spatially and temporally vareid, the simulation of the runoff from the watershed is frequently conducted with the constant rainfall distribution assumption. However, the runoff simulated with this assumption indicates over the certain accuracy limitation and the difference by this assumption is bigger in the case of the moving storm which can be frequently indicated with the typhoon, cyclone and hurricane and so on. In this paper, the runoff characteristics of the moving storm are investigated using GIS technique and the isohyetal map observed from 16:00 to 23:00 on August 2, 1999 to the Chun Yang rain gage. The runoff simulated by the moving storms moving to the eight different directions is compared with the others and indicates the big difference with the maximum runoff in the SE direction in the Bokha experimental watershed. Also, the runoff by the moving storm having different moving velocities is compared with the others and indicates the big difference with the bigger discharge in the slowly moving storm. Through the simulation using GIS technique in the watershed, the advantages of the easy preparation of the data and the short computational time can be obtained.
