Priority-Flood: An Optimal Depression-Filling and Watershed-Labeling Algorithm for Digital Elevation Models
Richard Barnes, Clarence Lehman, David Mulla
Depressions (or pits) are low areas within a digital elevation model that are surrounded by higher terrain, with no outlet to lower areas. Filling them so they are level, as fluid…

An Efficient Assignment of Drainage Direction Over Flat Surfaces in Raster Digital Elevation Models
Richard Barnes, Clarence Lehman, David Mulla
In processing raster digital elevation models (DEMs) it is often necessary to assign drainage directions over flats---that is, over regions with no local elevation gradient. This p…
