elder_creek_floodplain: Elder Creek Flow to Floodplain Habitat Area Relationship
In FlowWest/cvpiaHabitat: Estimate Spawning and Rearing Habitat

Description Usage Format Fall Run and Steelhead Modeling Source Examples

A dataset containing the floodplain habitat area in acres as a function of flow in cubic feet per second

1	elder_creek_floodplain

dataframe with 31 rows and 4 variables:

flow_cfs: integer flow value in cubic feet per second
FR_floodplain_acres: fall run floodplain acreage
ST_floodplain_acres: steelhead floodplain acreage
watershed: name of watershed

A 5.40 mile portion of the entire mapped rearing extent of 7.10 miles was modeled using Central Valley Floodplain Evaluation and Delineation (CVFED) HEC-RAS hydraulic model. Of the entire mapped rearing extent, 7.10 miles were classified as low gradient and 0.00 miles were classified as high gradient based on a geomorphic analysis. Floodplain area per unit length was determined for the modeled extent and applied to determine areas for the non-modeled extent. A scaling factor of 0.1 was applied to the area per unit length for the high gradient extent. No scaling factor was applied to the low gradient extent.
