Abstract: The specification of the land cover characteristics is essential to have runoff simulated by a Rainfall-Runoff (R-R) model in watershed hydrology. The recent availability of land cover map from remotely sensed data makes the specification of the land cover characteristics easier but it is unlikely that the rainfall-runoff models incorporate all spatial scales of the land cover map in need of application. On the basis of mass balance theory, a simple strategic approach acceptable to R-R model is proposed to represent natural vegetative heterogeneity. It is a simple method to calculate the effective value of vegetation parameters that determine surface runoff at the length scales used in R-R model. The proposed method provides a reasonably realistic description of area-averaged vegetation nature and characteristics.
