GatherStreamInds: Gather upstream or downstream distance from a given starting...

In NCAR/rwrfhydro: R tools for the WRF Hydro Model

Description

A non-recursive function (recusive version runs in to stack overflow problems for large domains. Both are available internally).

Usage

GatherStreamInds(stream, start, linkLengths)

Arguments

stream	List of stream information containing either from/to and start and end positions, returned from ReExpNetwork.
start	Indexed location (NOT comID) of where stream starts
linkLengths	Vector of link lengths for each re-indexed reach, contained in reExp.nc.

Value

List containing indices, accumulated distance from start, and tip information (0=not a tip, 1=a tip, 2=temporary tip/still solving)
