Fish Passages

The effect of dams on river ecology and fish migration is a worldwide concern. FLOW-3D is used by professionals and academics to improve existing fish passages, modify fish passage designs for site-specific needs, and to develop novel approaches based on the physiology and behavior of different fish species. FLOW-3D is also used to model and design aeration systems for low-oxygen impounded waters and to mitigate unwanted air entrainment and total dissolved gas due to dam spillways.

FLOW-3D is an accurate simulation software used to model fish passages

Simulation of the weir of the Third Dam on Somes Brook. Analysis of the fish passage was performed to appropriately repair structure so that the alewife can navigate it. Image colored by velocity magnitude.
