SYNOPSIS

v.stream.inbasin

v.stream.inbasin --help

v.stream.inbasin [-s] input_streams=name [input_basins=name] [draindir=name] [cat=string] [x_outlet=string] [y_outlet=string] [output_basin=name] [output_streams=name] [output_pour_point=name] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

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
x_outlet=string: Approx. pour point x/Easting: will find closest segment
y_outlet=string: Approx. pour point y/Northing: will find closest segment
output_basin=name: Vector output drainage basin; Name for output vector map
output_streams=name: Streams within vector output drainage basin; 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.
