r.agent
r.agent shall provide an inital base for organizing worlds with raster playgrounds and agents in. Still under development.
- Author: Michael Lustenberger
r.area
r.area can be used to remove, areas smaller than treshold, reclass according areas (similar to r.reclass area, but work in cells, not hectares and allow create more classes)
- Author: Jarek Jasiewicz
r.clump2
r.clump2 finds all areas of contiguous cell category values in the input raster map layer name.
r.convergence
....
r.convert

r.damflood
The definition of flooding areas is of considerable importance for both the risk analysis and the emergency management. This command is an embedded GRASS GIS hydrodynamic 2D model that allows to obtain flooding area due to a failure of a dam, given the geometry of the reservoir and of the downstream area, the initial conditions and the dam breach geometry.

r.gdd
r.gdd calculates (accumulated) growing degree days (GDDs) and Winkler indices from several input maps with temperature data for different times of the day.

r.regression.multi
r.regression.multi calculates a multiple linear regression from raster maps. r.regression.multi is designed for large datasets that can not be processed in R.
- Author: Markus Metz
r.regression.series
r.regression.series is a module to calculate linear regression parameters between two time series, e.g. NDVI and precipitation.
- Author: Markus Metz
r.stream.basins
r.stream.basins: Calculate basins according user input.
r.stream.channel
r.stream.channel: Calculate some local properties of the stream network. It is supplementary module for r.stream.order and r.stream.distance to investigate channel subsystem.
r.stream.distance
r.stream.distance: Calculate distance to and elevation above streams and outlets according user input. It can work in stream mode where target are streams and outlets mode where targets are outlets.
r.stream.extract
r.stream.extract: Stream network extraction.
r.stream.order
r.stream.order: Calculate Strahler's and Horton's stream order Hack's main streams and Shreeve's stream magnitude. It uses r.watershed or r.stream.extract output files: stream, direction and optionally accumulation. Output data can be either from r.watershed or r.stream.extract but not from both together.
r.stream.segment
r.stream.segment: The module is designed to inverstigate network lineaments and calculate angle relations between tributaries and its major streams.
r.stream.slope
r.stream.slope: Calculates the difference between elevation of current cell and downstream cell, gradient and max curvature on the basis of a flow direction map. It can be used to calculate the directional slope using a flow direction map.
r.stream.snap
r.stream.snap: is a supplementary module for r.stream.extract and r.stream.basins to correct position of outlets or stream initial points as they do not lie on the streamlines.
r.stream.stats
r.stream.stats: Calculate Horton's and optionally Hack's statistics according to user input.
r.sun.angle
....
r.threshold
....
r.vol.dem
