抄録

In the recent. development off topographical measurement method using laser beams shed from an airplane, high resolution ground data referred to as digital elevation models (DEM) have become available. DEM gives us ground 3D data with a resolution of an order of one meter in the horizontal direction and an order of centimeters in the vertical direction. With such a densely distributed topographical data, the accuracy of runoff analysis would become much better than the previous ones and a more sophisticated analysis would become possible. In the present study, a virtual tracer method is proposed in order to determine the catchment area for an arbitrary location within the river basin. A runoff analysis for a relatively small area in Kobe city is also performed by using the DEM data and locally distributed time-dependent rain zones.
