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.
