v.stream.inbasin - GRASS GIS manual

NAME

v.stream.inbasin - Subset a stream network into just one of its basins

KEYWORDS

vector, stream network, basins, hydrology, geomorphology

SYNOPSIS

v.stream.inbasin

v.stream.inbasin --help

v.stream.inbasin [-s] input_streams=name [input_basins=name] [draindir=name] [cat=string] [coordinates=east,north] [output_basin=name] [output_streams=name] [output_pour_point=name] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-s: Snap provided coordinates to nearest segment endpoint
--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
coordinates=east,north: Pour point coordinates; The alogorithm will find the closest stream 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. 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.
