This function returns an estimated floodplain area based on watershed, species and flow.
set_floodplain_habitat(watershed, species, flow, flow2 = NULL)
| watershed | a watershed defined for the SIT model |
|---|---|
| species | one of 'fr' (Fall Run), 'sr' (Spring Run), or 'st' (Steelhead) |
| flow | 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]
