Algorithm for hydrological analysis that generates the drainage network from a digital terrain model (DTM).
Main feautures:
- Vector stream network (raw and smoothed)
- Drainage directions; Topographic index ln(a/tan(b))
- Half basins.
Main steps:
1) Fill sinks (Wang & Liu algorithm)
2) Flow calculation and stream delineation
3) Raster to vector conversion
4) Geometry smoothing
