Create Duration Suitability Rating Curve for a streamgage

habitat_drc(
  streamgage,
  habitat_type = "rearing",
  run = "fall",
  wy_group = "Dry",
  gradient = "Valley Foothill"
)

Arguments

streamgage

Three-letter CDEC identifier for the streamgage

habitat_type

Either "rearing" (default) or "spawning"

run

One of "fall" (default), "late fall", "winter", "spring", or "steelhead"

wy_group

Either "Dry" or "Wet" for water year type scenario

gradient

For rearing, either "Valley Foothill" (default) or "Valley Lowland"

Value

A tibble with columns for flow (flow_cfs) and duration habitat suitability index (durhsi)

Examples

habitat_drc("FSB", habitat_type="rearing", gradient = "Valley Foothill")
