Description

This function identifies small (pathlength or area) headwater catchments and collapses them into the existing network until none remain. Headwaters are those segments in which there are no inflows (!ID %in% toID).

Usage

collapse_headwaters(
  network_list,
  min_area_sqkm = 3,
  min_length_km = 1,
  verbose = TRUE,
  cache_file = NULL
)

Arguments

network_list	a list containing flowpath and catchment sf objects
min_area_sqkm	The minimum allowable size of the output hydrofabric catchments
min_length_km	The minimum allowable length of the output hydrofabric flowlines
verbose	should messages be emitted?
cache_file	If not NULL results will be written to a provide path (.gpkg)

Value
