WHAT THE EVIDENCE SAYS
Bolstadfjord simulations indicate changing sill depth, external water density and freshwater discharge timing alters deep-basin renewal; a modeled constant regulated release prevented renewal in one scenario.
WHY IT MATTERS / OUR READ
Infrastructure water-flow timing and density matter as much as annual volume for coastal ecology.
CAVEATS / UNCERTAINTY
Scenario models, not observed new dam or dredging outcomes; site-specific bathymetry limits transfer.
