DESCRIPTION

v.stream.profiler builds and exports plots and data sets of river long profiles, slope-accumulation (e.g., slope-area), and more for topographic analysis. It currently works only in a downstream-directed walk, for a single channel, from the chosen segment until the downstream-most point in the network. It takes in the adjacency structure supplied by v.stream.network.
