watershed: Tools for Watershed Delineation

Description

This is a simplified set of tools for deriving a river network from digital elevation data. The package relies on GRASS GIS (v. 7.4 or 7.6) to do the heavy lifting. An installation of GRASS and the rgrass7 package is required for watershed to function. Note that this is meant to be a simplified workflow for watershed delineation using only R code; for more options users can use rgrass7 to access GRASS GIS functions directly.

Key functions

• delineate() Produce a stream map from a digital elevation model

• pixel_topology() Construct river network topologies

• reach_topology() Construct river network topologies

• catchment() Compute catchment areas

Datasets

• kamp_dem An example digital elevation model for the Kamp river in Austria

• kamp_q Measured discharge in the Kamp river
