  • r.drain: Traces a flow through an elevation model on a raster map.
  • r.fillnulls: Fills no-data areas in raster maps using v.surf.rst splines interpolation
  • r.fill.dir: Filters and generates a depressionless elevation map and a flow direction map from a given elevation layer.
  • r.flow: Construction of slope curves (flowlines), flowpath lengths, and flowline densities (upslope areas) from a raster digital elevation model (DEM)
  • r.topidx: Creates topographic index [ln(a/tan(beta))] map from elevation map.
  • r.terraflow: Flow computation for massive grids.

Groundwater flow

  • r.gwflow: Numerical calculation program for transient, confined and unconfined groundwater flow in two dimensions.
  • r3.gwflow: Numerical calculation program for transient, confined groundwater flow in three dimensions.

Hydrological models

  • r.topmodel: Simulates TOPMODEL which is a physically based hydrologic model.
