We’ve developed a new plugin for InVEST which provides an alternate version of the RouteDEM utility. This plugin includes a “Threshold Flow Accumulation Range” input, allowing it to compute outputs for a range of TFAs in a single run. The plugin README provides additional details about how to format the new range input, as well as instructions for plugin installation and use. The GitHub repository can be found here.
Note: Since threshold flow accumulation is only relevant in cases where streams are calculated from the flow accumulation output, this plugin always calculates flow direction, flow accumulation, and streams.
This plugin is compatible with InVEST version >= 3.17.0
