Opportunity
Modeling the behavior of rivers, lakes, and other inland waterways may be just as challenging as analyzing oceanfront phenomena.
As part of an effort to restore the salmon fishery in the state of Washington, barriers to fish were removed from Wilson Creek in Kittitas County. Optimizing the habitat required sophisticated analysis.
Solution
Mott MacDonald was retained to help increase complexity and enhance fish habitat in the creek. We provided services including data analysis, survey, construction estimate, engineering plans, and construction administration.
We brought an array of advanced tools to the job: US Army Corps of Engineers models such as SED2D and CMS, as well as the advanced 2D and 3D models MORPHO, FLOW3D, and others.
Outcome
A specially designed weir now ensures the correct flow depth and velocity for fish to pass a decommissioned diversion structure.
