cbec applied and refined a 2D hydrodynamic model using MIKE 21FM.

The MIKE 21FM model developed by cbec encompasses a complex network of tidal channels (both natural and man-made) within the Yolo Bypass-Liberty Island-Cache Slough Complex. The main goal of the Northern Liberty Island Fisheries Enhancement Project was to assess the feasibility, sustainability, and regional benefits of implementing various proposed enhancements (e.g., levee breaches, ditch plugs, pilot channels, etc.) within Stair Steps 1 and 2 in northern Liberty Island under tidal and flood regimes.

These proposed enhancements are intended to create and enhance delta smelt and salmonid habitat in the project areas.
