Estuaries depend on the transport of nutrients and sediments from the open sea
to help maintain a prosperous environment. One of the major transport mechanisms
is the propagation of large two dimensional vortical structures. At the mouth of an
inlet, tidal
flow forces the formation of two dimensional vortical structures whose
lateral extent is much greater than the water depth. After the starting jet vortex
dipole detaches from the inlet, secondary vortices shed due to separation from the inlet
boundary and eventually reach the starting-jet dipole. An idealized inlet con figuration
was utilized for laboratory experiments detailing the formation and propagation of
the vortex structures with water depths of 3, 5, and 9 centimeters and
flow Froude
scaled to inlets along the Texas coast. Using surface particle image velocimetry, the
entrainment of the secondary structures into the vortex system are shown as well as
variations in characteristics such as trajectory, size, vorticity, and circulation for the
vortices as they move downstream.
