Upscaling and Downscaling - Dynamic Models

Abstract

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 chapter discusses upscaling and downscaling as it applies to dynamic hydrological modeling. It is not meant to be an exhaustive discussion covering the entire range of scale issues in hydrology, or hydrological modeling, rather it attempts to summarize the relevant issues and illustrate some approaches used to address upscaling and downscaling in model development and application.
