Yolo Bypass Salmonid Habitat Restoration and Fish Passage Project

Existing conditions model output

Existing conditions model output

cbec has recently been contracted by DWR as a subconsultant to HDR to perform hydrodynamic modeling of project alternatives for the Yolo Bypass Salmonid Habitat Restoration and Fish Passage Project (Project) Environmental Impact Statement and Environmental Impact Report (EIS/EIR).

cbec is working cooperatively and collaboratively with DWR and the Bureau of Reclamation, and their consultants.

cbec developed and calibrated a TUFLOW Classic model for the Yolo Bypass and vicinity to support the evaluation of multiple alternatives to meet fish passage and habitat inundation objectives. Existing topographic and vegetation information was thoroughly reviewed, additional surveys were performed, long-term boundary conditions were prepared, alternatives were configured, and post-processing tools were developed for examining the model outputs and providing formatted information to other technical teams.

cbec will perform alternatives analyses in support of development of the EIS/EIR, including inundation analysis, flood impacts analysis, water temperature analysis, sedimentation/ erosion analysis, water allocation analysis, and groundwater impact analysis.
