  text: A precise understanding of the mechanisms causing phytoplankton blooms in
    reservoirs is still lacking, especially in large riverine reservoirs. To better
    understand these blooms, the role of the complex hydrodynamics caused by dam operation
    must be quantified. Here we examine how synergistic hydrodynamic processes, rather
    than individual metrics, trigger blooms in Xiangxi Bay, a typical tributary bay
    of the Three Gorges Reservoir, China. We used a 3D ecological-hydrodynamic model,
    which integrated hydrodynamics with the abiotic factors that limit phytoplankton
    growth to simulate one whole year (2010). By implementing a scaling criterion,
    we quantified the contribution of local phytoplankton growth and hydrodynamic
    processes, including advection transport and vertical mixing, on bloom dynamics.
    Results indicated vertical mixing was the main process inhibiting blooms in colder
    months (from October to February) but horizontal advection, which flushed and
    diluted blooms, was dominant in warmer months (from May to July) when stratification
    was intense and nutrients were replete. Accordingly, blooms occurred when both
    vertical mixing and horizontal advection were low. We suggested a potential dam
    operation strategy to mitigate blooms during stratification, which involves withdrawing
    the warm surface water from upstream reservoirs to increase horizontal flows in
    the surface layer. Extending the application of critical turbulence model, our
    study shows how vertical mixing and horizontal advection rate interact with phytoplankton
    growth rate to drive blooms in highly dynamic riverine systems.
