The long-term goal of our research group is to develop an understanding of how environmental fluid dynamics affect the biochemical processes in lakes, rivers, and watersheds. We conduct laboratory and field measurements to quantify the interaction between small-scale fluid motion and freshwater aquatic organisms, including bacteria, suspended algae, zooplankton and periphyton. Turbulent fluid-flow conditions, characterized by energy dissipation levels, are integrated with biomass accrual, metabolic rate, mobility, thin layer formation, and nutrient uptake. The interactions are characterized in most cases by nonlinear and non-equilibrium functional dependencies, which require extensive measurements of spatial and temporal heterogeneities of dependent variables and drivers across the scales. These research findings enable a mechanistic foundation towards formulating process-based water quality models in aquatic ecosystems.
