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

Description Usage Format Fall Run and Steelhead Modeling Examples

A dataset containing total inundated floodplain area in acres as a function of flow in cubic feet per second.

1	bear_creek_floodplain

dataframe with 30 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

No site-specific hydraulic modeling was available for this watershed. A flow to floodplain area relationship was generated for this watershed by scaling the flow to floodplain area relationship for Deer Creek based onhydrologic and geomorphic analyses. Flows and corresponding floodplain areas per unit length were calculated for this watershed as 0.25 percent of DeerCreek values based on the ratio of mean flow from December to June between this watershed and Deer Creek. Of the entire mapped 17.30 mile rearing extent in this watershed, 4.32 miles were classified as low gradient and 12.98 miles were classified as high gradient based on a geomorphic analysis. 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.
