Central Valley Floodplain Evaluation and Delineation (CVFED) HEC-RAS hydraulic model

Fall Run Modeling

A 17.14 mile portion of the entire mapped rearing extent of 17.14 miles was modeled using Central Valley Floodplain Evaluation and Delineation (CVFED) HEC-RAS hydraulic model. Of the entire mapped rearing extent, 17.14 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.

Spring Run and Steelhead Modeling

A 17.14 mile portion of the entire mapped rearing extent of 31.67 miles was modeled using Central Valley Floodplain Evaluation and Delineation (CVFED) HEC-RAS hydraulic model. Of the entire mapped rearing extent, 17.14 miles were classified as low gradient and 14.53 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.
