Pollution was held at the University ofVirginia in Charlotteswllc, Virginia, April 8 to 14. 1973. The Symposium was sponsored jointly
by the International Union of Theoretical and Applied Mechanics (IUTAM)
and the International Union of Geodesy and Geophysics (IUGG). The
scope covered by the Symposium was similar to that of the IUTAM--IUGG
Symposium on Atmospheric Diffusion and Air Pollution held in Oxford,
England in 1958’ and has some similarity to the symposia at Marseille,
France in 19612 and Kyoto, Japan in 19M3 organized by the two Unions.
The two IUGC Associations particularly concerned with the scope of the
Symposium are the International Association of Meteorology and Atmospheric Phjsics (IAMAP) and the International Association of the Physical
Sciences of the Ocean (IAPSO).
The main purpose of the Symposium was to survey our present knowledge
of turbulent diffusion as related to environmental pollution. The scope
included theoretical and experimental studies of turbulent diffusion in fluid
dynamics. atmospheric physics. and physical oceanography; the relation
between the Eulerian and Lagrangian statistics of turbulent structure; the
dispersion and deposition of pollutants; turbulent mixing of chemically
reacting species; large-scale and global dispersion of pollutants and predictability of pollutant concentration patterns; and some basic aspects of
their mathematical and physical modeling. In one sense, the Symposium
was an IUTAM-.IUGG response to the 1972 United Nations Conference
on the Hunian Environment held in Stockholm, surveying the frontiers of
knowledge in the field of turbulent diffusion in environmental pollution.
Participation in the Symposium was by invitation, and the selection of
papers and invited participants was made by the Scientific Committee
appointed by the two International Unions. About 130 participants and
observers took part in the Symposium representing 17 countries (Australia,
Belgium. Bulgaria. Canada. Denmark, France, Fed. Rep. Germany. India
