SMNET for R

Fits flexible additive models to data on stream networks, taking account of the branching structure and flow connectivity on the network. Models are fitted using penalised least squares. Details about the models and an overview of the similarities and differences to spatial stream-network models can be found in Rushworth et al. (2015)

rdwplus package for R

The rdwplus package for R statistical software provides the functionality to calculate six spatially explicit watershed metrics that account for the Euclidean or flow length distance to the stream or outlet, as well as the probability for overland runoff. It is a fully open-source implementation of the IDW-PLUS (inverse distance weighted percent land use for streams) ArcGIS custom toolset described in Peterson and Pearse (2017), which is no longer supported. The rdwplus package is available for download from CRAN, with more the most recent version available on github.

The rdwplus package can be used to generate a suite of spatially explicit watershed metrics including inverse Euclidean distance to the outlet and stream (iEDO and iEDS, respectively), inverse flow length to the outlet and stream (iFLO and iFLS, respectively), and the hydrologically active inverse flow length to the outlet and stream (HAiFLO and HAiFLS, respectively).
