Filling Natal Tributary and Regional Habitat

Allocates juvenile fish onto the floodplain and in-channel habitat. Once available habitat is full fish are assigned to out migrate. The fill_natal function is used to route fish within their natal tributary and the fill_regional function is used to route fish on the mainstem, bypasses, and deltas.

fill_natal(
  juveniles,
  inchannel_habitat,
  floodplain_habitat,
  territory_size = springRunDSM::params$territory_size,
  up_to_size_class = 2,
  yearlings = FALSE
)

fill_regional(
  juveniles,
  habitat,
  floodplain_habitat = NULL,
  territory_size = springRunDSM::params$territory_size,
  up_to_size_class = 3
