merced_river_floodplain: Merced River 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	merced_river_floodplain

dataframe with 22 rows and 3 variables:

flow_cfs: integer flow value in cubic feet per second
floodplain_acres: fall run floodplain acreage (use for Steelhead when required)
watershed: name of watershed

A 25.50 mile portion of the entire mapped rearing extent of 51.76 miles was modeled using Central Valley Floodplain Evaluation and Delineation (CVFED) HEC-RAS hydraulic model. Of the entire mapped rearing extent, 34.60 miles were classified as low gradient and 17.16 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.
