antelope_creek_floodplain
dataframe with 22 rows and 5 variables:
integer flow value in cubic feet per second
fall run floodplain acreage
spring run floodplain acreage
steelhead floodplain acreage
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 0.47 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 31.62 mile rearing extent in this watershed, 10.48 miles were classified as low gradient and 21.14 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.
