set_floodplain_habitat.RdThis function returns an estimated floodplain area based on watershed, species and flow.
set_floodplain_habitat(watershed, species, flow, flow2 = NULL)a watershed defined for the SIT model
one of 'fr' (Fall Run), 'lfr' (Late Fall Run), 'sr' (Spring Run), or 'st' (Steelhead)
a flow value in cubic feet per second
floodplain habitat value in square meters
The Lower-mid Sacramento River has two nodes, one above Fremont Weir (C134) and one below (C160). When calculating habitat for the Lower-Mid Sacramento river, calculate the habitat at each flow node and sum them proportion to the length of stream above and below the weir:
35.6/58 * (habitat at C134) + 22.4/58 * (habitat at C160)
Regional Approximation: When a watershed has no associated floodplain modeling, an approximation is made. [insert method description]
