Project Summary: We propose an integrated effort of using high-resolution measurements and 3-D hydrodynamics modeling to couple the transport algorithms of drift processes of carp eggs and larvae. This study addresses the research priority in identifying river characteristics that infer resistance and resilience to establishment and impacts of aquatic invasive species in the Upper Mississippi River basin. Our focus will be the centimeter- to meter- scale river turbulence associated with channel-training structures in the Mississippi River basin, and its role in helping or hindering egg/larval transport and retention. The outcome of this project will inform the better drift modeling that directly resolves the effect of localized turbulence rather than using empirical eddy viscosity and unified dispersion parameterization in the current best practice.
