Computational Fluid Dynamics Study of Fish Passage and Aquatic Habitat for Redesigned Whitewater Structures in Meadow Park

Popis výsledku v původním jazyce

A 3D Computational Fluid Dynamics (CFD) model was developed to compare hydraulic parameters between redesigned structure geometries and pre-flood whitewater structure geometries. Of the four geometries analyzed, the structure containing a fish notch in the center chute consistently produced the most desirable hydraulic conditions for fish passage, aquatic habitat, and recreational use at Meadow Park. The study also found that these results may not be universal, whitewater structure geometry selection ishighly dependent on local site conditions. Though this study identified the Fish Notch geometry as the preferred alternative, site specific conditions such as channel geometries, hydrology, and 3D hydrodynamics may produce differing results in larger rivers and other locations. The study also evaluated the whitewater characteristics of the structures with regards to recreational value to in-stream users. The revised structure geometries for the Meadow Park Whitewater Park redesign were
