- Pit removal by flooding to ensure hydraulic connectivity within the watershed
- Computation of flow directions and slopes
- Contributing area using single and multiple flow direction methods
- Multiple methods for the delineation of channel networks including curvature-based methods sensitive to spatially variable drainage density
- Objective methods for determination of the channel network delineation threshold based on stream dropsStream ordering
- Delineation of watersheds and subwatersheds draining to each stream segment and association between watershed and segment attributes for setting up hydrologic models.
- Specialized functions for terrain analysis, including:
- Wetness index
- Distance to streams
- Downslope influence function to map locations downslope that may be influenced by activities in an area
- Upslope dependence function to map the locations upslope where activities have an effect on a downslope location
- Decaying accumulation that evaluates upslope contribution subject to decay or attenuation
- Concentration limited accumulation
- Transport limited accumulation
- Reverse accumulation
