Parameters:

input_streams=name [required]
Stream network
Or data source for direct OGR access
input_basins=name
Subbasins built alongside stream network
Or data source for direct OGR access
draindir=name
Drainage directions (needed if exact coordinates used)
Name of input raster map
cat=string
Farthest downstream segment category
coordinates=east,north
Pour point coordinates
The alogorithm will find the closest stream segment

Name for output vector map
output_pour_point=name
Basin outlet
Name for output vector map

DESCRIPTION

v.stream.inbasin uses the output of v.stream.network to select only those streams (and sub-basins) that are upstream of (and inclusive of) a selected link in the network. It is used as a step to develop GSFLOW model inputs for a watershed, but need not be exclusively used for that purpose. v.stream.inbasin expects the stream network attributes created by v.stream.network and named using the names v.stream.network uses by default. In other words, v.stream.inbasin will work on the output v.stream.network with default attribute names.
