IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

On the interaction of mississippi river waters with the deepwater horizon oil spill (gulf of mexico)

er Horizon oil rig explosion caused ~7*105 m3 of oil gushing from the Northern Gulf of Mexico bottom.
The important and numerous effects of the DwH oil spill on the deep and coastal environment of the Northern Gulf of
Mexico motivated this study. It is also a unique topic relating the dynamics of a large scale river plume with the transport
and fate of hydrocarbons. Numerical simulations, satellite and in situ data were used to show the unique influence of a
large river plume on a surface oil patch resulting from a deep oil release. The buoyant plume induced circulation,
modified by shelf and slope flows, was found to substantially influence the near surface transport of oil. Periods of low
discharge reduced the dominance of buoyancy-driven effects, but an interval of sustained downwelling-favorable winds,
combined with river induced stratification, resulted in a strong westward current and surface oil patch extension. It was
also hypothesized that the high Mississippi River discharge in May 2010 might have helped to initially keep oil from
reaching coastal marshes.Form Required :
