Updating an invasive fish and native fish passage model for locks and dams

Project manager: Anvar Gilmanov   

Funded by: Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources

Description: This project will create an updated version of Computational Fluid Dynamics Agent-Based (CFD-AB) fish passage model using new field data that can better help stop invasive carps while allowing native fish to pass through Mississippi River locks and dams.

The new field data is being generated by an ongoing field study of fish behavior and passage at Lock and Dam 2. Parameters on fish behavior will then be updated in the CFD-AB fish passage model developed earlier by [Zielinski et al., 2018] to improve it. We will use this updated CFD-AB model to predict fish passage for invasive carp (silver carp, common carp) and two native fishes (channel catfish, lake sturgeon) at two model lock and dams (2 and 8). The updated CFD-AB model will allow to determine optimum spillway gate positions to stop invasive carps at these sites. We will share these new data with the U.S. Army Corps of Engineers and the Minnesota DNR.
