HYBASBasinLimits: Create HydroBASINS delineation

In ECCC-MSC/Basin-Delineation: Finds upstream area and upstream stations

Description

Uses a classification code to build an approximate drainage basin for a hydrometric station using HydroBASINS polygons.

Usage

HYBASBasinLimits(df, HYBAS, code, outdir, hyb_id = "HYBAS_ID",
  stn_id = "station_number")

Arguments

df	data.frame with exactly 1 row containing station names and the HYBAS_ID of the HydroBASINS polygon that contains each station.
HYBAS	SpatialPolygonsDataFrame of hydrobasins polygons
code	character, classification code describing location of station within cell and on stream
outdir	character, directory in which to save output shapefile
hyb_id	character, name of column containing ID of HydroBASINS sub-basin that contains the station
stn_id	character, name of column containing the station number

Details

This function uses the following classification system for the code parameter, which describes the location of the station relative to the containing hydrobasin and the waterbody with which it is associated:

P: containing sub-basin has 2 input sub-basins Pcb Waterbody continues upstream and station on main branch below confluence Pct Waterbody continues upstream and station on tributary branch above confluence Pcm Waterbody continues upstream and station on main branch above confluence Ps Waterbody terminates upstream within sub-basin

I: containing sub-basin has 1 input sub-basins Ic Waterbody continues upstream Is Waterbody terminates upstream within sub-basin

T: containing sub-basin has 0 input sub-basins

The output shapefile contains the containing hydrobasin.

Value

character, path to created shapefile
