Transferring information from one spatial or temporal scale to another (scaling) presents one of the most daunting scientific challenges in hydrology. This is particularly true in hydrological modeling where disparities in scale exist in nearly every phase of model development and application. This article discusses scales, hydrological processes, heterogeneity, upscaling, and downscaling as applied to dynamic hydrological modeling. It is not meant to be an exhaustive discussion covering the entire range of scale issues in hydrology, or of hydrological modeling, rather it attempts to summarize the relevant issues and illustrate some approaches using specific examples to address upscaling and downscaling in hydrological model development and application.
