WebDec 27, 2024 · An estuary is a long bay that opens onto the ocean. It also has a source of buoyancy, like the freshwater that comes from a river, and it needs some energy to mix the ocean and river waters. ... This energy usually comes from tidal currents. With these three ingredients: ocean water, river water, and tidal mixing, estuaries around the world ... Web[1] A two-dimensional numerical model is used to study the diapycnal flow through a tidal front with passive tracers. In a basic numerical experiment a passive tracer is released into the bottom water at the offshore edge of a tidal front, and it subsequently moves on-bank with a velocity that decreases with time. This qualitatively agrees with a recent field …
