Abstract
In this paper, we report studies to understand the linkage between complex flow patterns and fish movement behaviour at the junction of the Georgiana Slough and the Sacramento River, near Walnut Grove, California. The flows at the junction are oscillatory and complex due to tidal influence. A 3D CFD model is developed to predict the flow patterns at the junction; the model is then validated by comparing with ADCP field data. An Eulerian-Lagrangian-agent method (ELAM) model is used to systematically analyze how measured fish movement, from acoustic-tag telemetry, may be linked to the water flow patterns. The developed too will ultimately be used to forecast how fish may respond to different guidance structure designs under varying river conditions.
