Fall Run and Steelhead Modeling

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.
