Popis:	The kinematic wave method is applied to evaluating the concentration time of overland flow in the basin composed of inclined planes and river channel. Firstly, the relationship between concentration time and geographical features of the basin is made clear for rainfall of constant intensity. Secondly, we evaluate quantitatively the effect of unsteadiness of rainfall on concentration time and peak discharge. The result of computation shows that concentration time is greatly influenced by the equivalent roughness coefficient of planes, and the concentration time defined in this study for unsteady rainfall is almost equal to that for rainfall of constant intensity.
