pipeSizingAlgorithm: Pipe diameter sizing algorithm

In DoeringA/urbandrain: Automated generation of a stormwater drainage networks using spatial data

Description

The conduit diameters are calculated and designed for a user defined storm event. Initially the sizing algorithm runs a SWMM model with all conduits having a diameter of 0.3 m by default (or smaller if defined). After each iteration, it is checked whether conduits still surcharge. If so, diameters of the surcharging conduits are increased by a nominal diameter. The algorithm stops if no conduit surcharge occurs any more. The final inp file is stored.

Usage

pipeSizingAlgorithm(
  inp,
  path_out,
  conduits_sf,
  junctions,
  outfalls,
  target,
  DN_start = 300,
  rpt_filename = "artificial_SWMM_model.rpt",
  inp_filename = "artificial_SWMM_model.inp",
  link_filename = "links_artificial_SWMM_format.shp"
)

Arguments

inp	A object of class inp. Containing a complete SWMM model.
path_out	A directory path to write the results to.
conduits_sf	A sf object containing polyline information.
junctions	A sf object containing junction point information.
outfalls	A sf object containing outfall point informations.
target	Either node_flooding or conduit_surcharge.
DN_start	Initial pipe diameter (unit: mm).
rpt_filename	File name for SWMM's report file.
inp_filename	File name for SWMM's input file.
link_filename	File name for a shp file containing the sized conduits.

Value

A sf object containing polylines with all attributes needed for the conduit section in SWMM's input file.
