Hi Everyone, Is there a way to add nodes to a stream network created by r.stream.extract and quickly query which nodes are upstream and which are downstream? For instance, maybe I have a wetland that sometimes is dry; and therefore, I would like to remove it from the stream network. Basically, I'm looking at routing flow accumulation down the network, accounting for storage in wetlands to determine a contributing drainage area for a given runoff event.
I assume that you can add the wetland nodes using v.net<http://v.net> somehow, but it isn't clear to me how to relate these nodes with each other (i.e. whether one node is upstream or downstream or on a different stream than another). Any hints would be greatly appreciated! Thanks, Mitch Mitchell Weier, P.E.
