Building channel networks for flat regions in digital elevation models
Abstract
Abstract Digital elevation models (DEMs) are data sources for distributed rainfall–runoff modelling in terms of providing the channel network for a watershed of interest. Assigning flow directions over flat regions is an important issue in the field of DEM processing and extraction of drainage features. Existing methods cannot fully incorporate the information of known drainage features and terrain surrounding the flat region. This study …
