Buoyant plumes are characterized by a distinct contrast in
properties between plume and ambient water. An understanding of
their physics is crucial for interdisciplinary study of estuarine
and coastal regions because discharge flow is often a source of
nutrients, biological species, sediment, and toxic contaminants.
This book investigates the nature of physical processes associated
with near field buoyant plumes, and describes the relationship
between processes. Two field sites, one thermal plume in
Massachusetts, USA, and the Merrimack River plume, Massachusetts,
USA are studied. Observed mixing in the near-field of the thermal
plume is driven by bottom friction. The industrial plume studied
here is dynamically similar to larger geophysical plumes, but
differs in important aspects that can be fully characterized by the
initial aspect ratio of the discharging plume. Estimates of three
non-dimensional parameters, which represent mixing, spreading, and
the bulk Richardson number, suggest that a quadratic relationship
exists between mixing and spreading for the river plume. Estimates
also yielded time scales for turbulence evolution that are
consistent with values in literature.
