  fsa,
  drc,
  fsa_q = q,
  fsa_wua = wua,
  drc_q = q,
  drc_dhsi = dhsi
)

Arguments

fsa: A data.frame or tbl_df containing a flow-to-suitable-area curve
drc: A data.frame or tbl_df containing a flow-to-duration-HSI curve
fsa_q: The unquoted name of the flow column in fsa (defaults to q)
fsa_wua: The unquoted name of the suitable area column in fsa (defaults to wua)
drc_q: The unquoted name of the flow column in drc (defaults to q)
drc_dhsi: The unquoted name of the duration suitability factor column in drc (defaults to dhsi)

Value

A tbl_df data frame with one row per flow (q) containing columns for the original suitable area (wua) and the new duration-weighted suitable area (durwua) along with interim calculation columns.
