A physically based model for calculating contributing area on hillslopes and along valley bottoms



A physically based model for calculating contributing area on hillslopes and along valley bottoms



Water Resources Research 39(12): 1332



Most existing methods of calculating contributing area are unable to accurately model the pattern of contributing area on hillslopes and along valley bottoms. This paper describes a new flow algorithm, the adjustable dispersion routing algorithm (ADRA). Rather than calculating contributing area using predetermined flow characteristics that are insensitive to location in the landscape, ADRA predicts channel location and adjusts flow characteristics accordingly.
