LakeDataOutlets: Identify LakeData Outlet SUBIDs

Description

Identifies the SUBID(s) corresponding to the outlet of each lake in a LakeData data frame.

Usage

LakeDataOutlets(ld, gd)

Value

An integer vector containing the SUBIDs identified as lake outlets. One or more SUBIDs may be returned for a lake if the lake contains multiple downstream outlets.

Arguments

ld

A data frame containing LakeData information (i.e. an imported 'LakeData.txt' file). Must contain the columns LAKEID and SUBID.

gd

A data frame containing GeoData information used to determine the upstream connectivity between SUBIDs (i.e. an imported 'GeoData.txt' file).

Details

A SUBID is identified as a lake outlet when all SUBIDs belonging to the same lake occur in the upstream area of that SUBID. The function uses AllUpstreamSubids() to determine the upstream SUBIDs.
