FLoWS - Functional Linkage of Watersheds and Streams
The FLoWS toolbox is a set of graph theoretic-based analysis tools that functionally link aquatic and terrestrial components of the landscape based on hydrologic processes (Theobald et al. 2006). These tools provide an efficient framework for navigating throughout the network, which makes it possible to calculate a variety of attributes related to network distance, flow direction, and terrestrial contributing areas.
Note that the FLoWS toolset is only used in conjunction with STARS versions < 2.0.0. All of the relevant FLoWS tools were incorporated into STARS version 2.0.0.
R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. The SSN package was developed for use with R. The Comprehensive R Archive Network

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)
